The results showed that the planting method for fresh edible "faba bean/spring maize+soybean-autumn maize/autumn soybean" was much easier to operate with the input-output ratio of about185.6%, and its yield and economic benefits were 2.09 and 1.83 times of that of the planting mode for three crops a year, significantly improving the agricultural yield and income of farmers. In addition, the cropping index of the planting mode for fresh edible fresh edible "faba bean/spring maize +soybean-autumn maize/autumn soybean" reached up to 350%, and planting faba bean once a year and soybean twice a year could make the biological fixation amount of nitrogen increase 350-450kg/m^2, which equaled to up to 700 kg/m^2 of urea, showing significant ecological and social benefits. Based on the comparison results, the high-yield culture techniques of the planting mode of fresh edible "faba bean/spring maize+soybean-autumn maize/autumn soybean" were summarized.展开更多

The objectives of the study were to evaluate the yield stability of the genotypes and the relative importance of different stability parameters for improving selection in faba bean. The study was conducted using a randomized complete block design with four replications. G × E interaction and yield stability were estimated using 17 different stability parameters. Pooled analysis of variance for grain yield showed that the main effects of both genotypes and environments, and the interaction effect, were highly significant(P ≤ 0.001) and(P ≤ 0.01), respectively. The environment main effect accounted for 89.27% of the total yield variation, whereas genotype and G × E interaction effects accounted for 2.12% and 3.31%, respectively.Genotypic superiority index(Pi) and FT3 were found to be very informative for selecting both high-yielding and stable faba bean genotypes. Twelve of the 17 stability parameters,including CVi, RS, α, λ, S2 di, bi, S(2)i, Wi, σ2i, EV, P59, and ASV, were influenced simultaneously by both yield and stability. They should accordingly be used as complementary criteria to select genotypes with high yield and stability. Although none of the varieties showed consistently superior performance across all environments, the genotype EK 01024-1-2ranked in the top third of the test entries in 61.5% of the test environments and was identified as the most stable genotype, with type I stability. EK 01024-1-2 also showed a17.0% seed size advantage over the standard varieties and was released as a new variety in2013 for wide production and named "Gora". Different stability parameters explained genotypic performance differently, irrespective of yield performance. It was accordingly concluded that assessment of G × E interaction and yield stability should not be based on a single or a few stability parameters but rather on a combination of stability parameters.展开更多

The development of simple sequence repeat (SSR) markers from expressed sequence tags (EST) provided a useful tool for investigation of its genetic diversity. The purpose of the present study was to investigate the genetic diversity of faba bean from China and Europe using EST-SSR markers. 5 031 faba bean ESTs from the NCBI database were downloaded and assembled into 1 148 unigenes. A total of 107 microsatellites in 96 unigenes were identified, indicating that merely 8.36% of sequences contained SSRs. The most abundant SSR within faba bean was tri-nucleotide repeat motif, and among all the tri-nucleotide repeats, the motif AAG/CTT was the most abundant type. Based on these results, 11 EST-SSR markers were used to assess the genetic diversity of 29 faba bean cultivars from China and Europe with two to three alleles per locus. The polymorphism information content value ranged from 0.0644 to 0.4278 with an average of 0.2919. Principal coordinate analysis (PCA) and phylogenetic clustering based on these 11 EST-SSR markers distinguished these cultivars into different groups. The results indicated that faba bean in China had a narrow genetic basis, and the additional sources of genetic cultivars/accessions should be introduced to enhance the genetic variability. The results of this study proved that the EST-SSR marker is very effective in evaluation of faba bean germplasm.展开更多

It is consumed in various forms and contributes to the improvement of soil fertility. However,its production and productivity are affected by biotic and abiotic constraints. Among the biotic constraints, the emerging faba bean gall disease, caused by Olpidium uiciae, is the major and most destructive disease wherever faba bean is grown. Field experiments were conducted at two locations(Farta and Tach Gayint districts) to evaluate the reaction of faba bean varieties to faba bean gall disease and to assess them for yield and yield components during the 2014 and 2015 main cropping seasons. Thirteen faba bean varieties and one local check were plantecd in three replications Lusing a randomized complete block design. The disease incidence and severity of faba bean gall were recorded(on a 1-9 scale) five tinmes at10-day intervals. A combined analysis of variance showed za significant difference(P < 0.05)among faba bean varieties with respect to the incidence and severity of gall disease at both locations. Disease incidence, severity, and AUDPC were lowest for variety Turmsa at both locatiOons, but this variety showed lhigh yield only at tlhe Farta location. 'The lhighest yields were obtained from varieties Degaga(1157.74 kg ha ') and Nc58(828.97 kg ha ') at Farta and Tach Gayint, respectively and these varieties slhowed low faba bean gall severity and AUDPC. Thus, higher-yielding faba bean varieties such as Degaga and Nc58 are recommended for faba bean production areas in northwestern Ethiopia.展开更多

Two hundred and forty-four samples from twelve producing regions were measured in both milled powder and intact seed forms. Partial least squares(PLS) regression was applied for model development. The model based on ground seed powder was generally superior to that based on the intact seed. The optimal seed powder-based models for protein, starch, and total polyphenol had coefficients of correlation(r2) of 0.97, 0.93 and 0.89, respectively. The relationship between nutrient contents and twelve producing areas was determined by two-step cluster analysis. Three distinct groupings were obtained with region-constituent features, i.e., Group 1 of high oil, Group 2 of high protein, and Group 3 of high starch as well as total polyphenol. The clustering accuracy was 79.5%. Moreover, the nutrition contents were affected by seeding date, longitude, latitude, and altitude of plant location. Cluster analysis revealed that the differences in the seed were strongly influenced by geographical factors.展开更多

The results showed that the germination percentage in the large seeds was the highest (100%), and the size of the seeds affected the length of the root and shoot as the large seeds gave the highest length for root (8.37 cm) and shoot (14.2 cm) compared to the medium and small seeds. So, for these results, the seed size is closely related to root and shoot length, number of leaves.展开更多

The uptake of K^+ reduced in the presence of both salts whereas uptake of Ca^2+ retarded mainly by Na2SO4. Chlorophyll content was affected mainly by NaCl, while Na2SO4 treatment lowered the rate of photosynthetic activity. Both salt compounds caused accumulation of free amino acids including free proline but reduced the protein content in the leaves. The salt tolerance capacity of the broad beans plant in which the observations of the effect of salinity determined by different concentrations of NaCI and Na2SO4 on growth, chloroplast pigments, photosynthetic, free amino acids, free proline, protein and inorganic elements on plants are combined with observations on growth and yield, in order to arrive at a better understanding of their salt tolerance, has been studied and discussed in this paper. The results for the latter only (fruiting stage) are presented.展开更多

The consequences of self-fertilization are important factors determining the germplasm management in such species with levels of heterogeneity and heterozygsity. Effects of self-fertilization on floral, yield and yield components characters were evaluated by comparing two levels of selfing, produced in bee-proof cages, in open-pollination at two locations in Sudan. Selfing process results in no significant differences in yield and yield components within each cultivar. Autofertile lines with reduced partial dependence on insects for seed set could be produced. Spatial isolation should be used to maintain the genetic purity of such lines. An alternate strategy for entries multiplication should focus on increasing heterozygosity and the maintenance of cross-fertilization inside the entries to prevent contamination with foreign pollens. Our results follow the previous knowledge on faba bean genetic resources conservation and management.展开更多

A total of 15,697 Differentially Expressed Genes (DEGs) with pathway annotation were discovered in RNA-Seq of the faba bean seeds. A total of 75 significant KEGG pathways abundance were discovered and 9 pathways were conserved within all genotypes. 41 significant pathways were found to be partially conserved within comparisons of 2 to 6 pairs of genotypes and 25 significant pathways were unique to single pairs of genotypes. There were 8 specific significant pathways discovered related to the faba bean seed Hydration Capacity trait and 9 specific significant pathways discovered related to the PSbMV seeds staining trait. The DEGs demonstrated the genetic distance between these varieties was confirmed by the breeding pedigree selection information and a PCA graph clearly illustrated the genetic distance within these genotypes.展开更多

Five inbred lines in at least S6 generation were developed and used to develop F1s hybrid (in all possible combination excluding reciprocal), lines mixtures (Syn-0) and synthetic generations of Syn-1. Evaluation of the entries showed the lines to have high general and specific combining ability, high yield and high average degree of cross-fertilization (0.36);hetrosis relative to mid-parent for yield was 67%. Lines mixture from four inbred lines (Hudeiba/93, Bassabier, Ed-Damar and Shabah) gave the highest yield of 3.40 t/ha for Syn-0 and 3.96 t/ha for Syn-1. Compared to the average yield t/ha of the pure stand of the four lines (3.11 t/ha), the increase in yield of was 9% in sy-0 and 27% in Syn-1. Compared to the individual yield t/ha of the pure stand of the lines, the performance of Syn-0 surpassed that of the individual pure stands of the linesby 14% for Hudiaba/93 and Bassabier and 4% for Ed-Damar and 7% for Shabah, whereas the increase in performance of Syn-1 compared to pure stand of the lines was 32%, 25% and 21%, respectively. The results confirm the previous knowledge on yield increase with successive syn-generations in faba bean due to the effects of heterogeneity and heterozygosity. Such results could be used as a base for an effective breeding program for improvement of yield of faba bean grown under the semi-arid zones.展开更多

A significant positive influence of temperature, CF, FF, incubation time and inoculums size on the protease production was evaluated by Plackett Burman Design. Among these, CF was the most influential factor. The enhancement of protease to 9127 U/ml was achieved with the optimization procedure on the medium composed of (g/l): CF, 40;FF 30, NaCl 2.0;KH2PO4 1;K2HPO4 1;CaCl2, 0.1;MgSO4 0.1. The cultures were conducted for 72 hours with an IS of 2%, at 30°C, an agitation speed of 150 rpm and an initial pH of 8.0. More interestingly, the optimization was accomplished using two cheap and local fermentation substrates, CF and FF, which could result in a significant reduction in the cost of medium constituents. The maximum alkaline protease production was 9127 U/ml after 72 h of incubation and showed 5-fold increase in protease production over the initial level.展开更多

All entries were grown in cages under two pollination conditions: presence of bees (cross-pollination) or absence of bees (self-pollination). The open-pollinated generations gave the highest performance in the presence and absence of bees. In the presence of bees, the open-pollinated and their inbred entries gave higher performance in all of the studied traits than in the absence of bees;the average improvement in yield and its components was 22%. The highest improvement percentage in yield performance was shown by more inbred entries (thrice-selfed > once-selfed), indicating that in faba bean populations, the performance of inbred generations was chiefly associated with the tripping of flowers, which is usually governed by successfully fertilized flowers, i.e., plants result from selfing in faba bean population needs to be visited by pollinating insects (bees) to set more seeds. It concluded that honeybee has an important role in increasing faba bean yield in semi-arid conditions;hence, it is important to provide a pollinator friendly environment for their foraging places and nesting sites to secure food supply.展开更多

Two faba bean cultivars Sakha 1 and Masr 3 were grown in two ridge widths 60 and 120 cm and received five rates of amino acids compounds (Power mix at rates 1.5 cm⋅L−1 “Pm1” and 3.0 cm⋅L−1 “Pm2”, Super mix at rates of 3.5 cm⋅L−1 “Sm1” and 7.0 cm⋅L−1 “Sm2”, as well as, water only “control treatment”). The treatments laid out in a split split plot distribution in randomized complete blocks design in three replications were used. Ridge width was randomly assigned to the main plots, faba bean cultivars were allocated in sub-plots and amino acids compounds were allocated in sub sub-plots. Shoot chemical composition and photosynthesis pigments, as well as, chemical composition in seed traits of faba bean were tested in the laboratories of Plant Physiology Section, Agricultural Botany Department, Faculty of Agriculture, Cairo University, Giza, Egypt. Wide ridge had higher nitrogen (N), phosphorus (P), potassium (K), total sugars and total free amino acids concentrations in faba bean shoot and seeds in addition to chlorophyll a (Chl a) and chlorophyll b (Chl b) in faba bean shoot, as well as, most seed yield attributes than those of the narrow one. Faba bean cultivar Sakha 1 had higher values of seed yield, yield attributes and quality than Masr 3 that achieved higher seed antioxidants. Also, amino acids compounds affected significantly all studied traits of faba bean plants. Pm2 recorded the highest values of chemical composition in faba bean shoot and seeds. Moreover, Pm2 gave the highest seed yield and yield attributes compared to others. The interaction between ridge width and faba bean cultivar was significant for total sugars and carotenoids concentrations in faba bean shoot and 100-seed weight, as well as, seed N content. Also, the interaction between ridge width and amino acids compound had significant effects on shoot and seed N, P, K concentrations, number of pods plant−1 and seed yield ha−1, as well as, total soluble phenols and total free amino acids concentrations. Moreover, the interaction between faba bean cultivar and amino acids compound had significant effects on shoot Chl a and b concentrations, number of seeds pod−1 and seed yield plant−1, as well as, seed N, total soluble phenols and total free amino acids concentrations. Wide ridge x faba bean cultivar x amino acids compound interaction had significant effects on photosynthesis pigments, number of seeds pod−1 and seed yield ha−1, as well as, seed N, total sugars, total soluble phenols and total free amino acids concentrations. High seed yield and quality were recorded by growing faba bean cultivar Sakha 1 in wide ridge with foliar spraying at rate of 3.0 cm⋅L−1 of power mix. On the other hand, growing faba bean cultivar Masr 3 in narrow ridge with foliar spraying at rate of 3.5 cm⋅L−1 of super mix had good antioxidants in faba bean seeds.展开更多

Seven treatments included five treatments (90 kg nitrogen “N” + 30 m3 farm yard manure “FYM”/fad, 80 kg N +30 m3 FYM/fad, 70 kg N +30 m3 FYM/fad and 400 g of Cerealine + 30 m3 FYM/fad for intercropping faba bean cultivar Spanish with sugar beet cultivar Gloria) and two treatments (90 and 20 kg N/fad for solid culture of sugar beet and faba bean, respectively, as recommended mineral N fertilizer rate) were compared in a randomized complete block design with three replications. Solid culture of sugar beet with the application of recommended rate (90 kg N/fad) gave the highest top, root and sugar yields/fad, as well as the percentage of purity compared with the other treatments in both seasons. Intercropping faba bean with sugar beet plants with application of 90 kg N + 30 m3 FYM/fad gave the highest number of leaves/plant, leaf area/plant, root length, root diameter and root weight/plant followed by intercropped sugar beet plants that fertilized with 80 kg N + 30 m3 FYM/fad compared with the other treatments in both seasons. On the other hand, intercropped sugar beet that received 400 g of Cerealine + 30 m3 FYM/fad had the highest percentages of T.S.S. and sucrose followed by 70 kg N + 30 m3 FYM/fad compared with the other treatments in both seasons. Solid culture of faba bean with the application of 20 kg N/fad gave the highest plant height, number of seeds/pod and seed yield/fad, meanwhile the highest number of branches/plant and pod length were achieved by intercropping faba bean with sugar beet with application of 90 kg N + 30 m3 FYM/fad followed by intercropped faba bean plants that fertilized with 80 kg N + 30 m3 FYM/fad compared with the other treatments in both seasons. However, intercropped faba bean plants that fertilized with 70 kg N + 30 m3 FYM/fad gave the highest number of pods per plant, number of seeds per pod, seed index and seed yield per plant compared with the other treatments in both seasons. Land equivalent ratio (LER), land equivalent coefficient (LEC) and relative crowding coefficient (RCC) were high by intercropping faba bean with sugar beet with the application of 80 kg N + 30 m3 FYM/fad indicating yield advantage was achieved. The value of aggressivity (Agg) of sugar beet was negative for all combinations indicating that sugar beet is dominated component in the present study. Intercropping faba bean with sugar beet with the application of 80 kg N + 30 m3 FYM/fad achieved higher total income and monetary advantage index (MAI) than the other treatments. Growing sugar beet plants in both sides of beds (1.2 m width) with one faba bean row in middle of sugar beet beds with the application of 80 kg N + 30 m3 FYM/fad decreased mineral N fertilizer rate by 10.00% of the recommended sugar beet mineral N fertilizer rate, as well as increased land usage and profitability for Egyptian farmers compared with sugar beet solid culture.展开更多

文摘The high-efficiency planting mode for five crops a year of fresh edible "faba bean/spring maize+soybean-autumn maize/autumn soybean" was introduced, and its yield and economic benefits were compared with the planting mode of three crops a year of "faba bean-spring maize/red bean". The results showed that the planting method for fresh edible "faba bean/spring maize+soybean-autumn maize/autumn soybean" was much easier to operate with the input-output ratio of about185.6%, and its yield and economic benefits were 2.09 and 1.83 times of that of the planting mode for three crops a year, significantly improving the agricultural yield and income of farmers. In addition, the cropping index of the planting mode for fresh edible fresh edible "faba bean/spring maize +soybean-autumn maize/autumn soybean" reached up to 350%, and planting faba bean once a year and soybean twice a year could make the biological fixation amount of nitrogen increase 350-450kg/m^2, which equaled to up to 700 kg/m^2 of urea, showing significant ecological and social benefits. Based on the comparison results, the high-yield culture techniques of the planting mode of fresh edible "faba bean/spring maize+soybean-autumn maize/autumn soybean" were summarized.

文摘Sixteen faba bean genotypes were evaluated in 13 environments in Ethiopia during the main cropping season for three years(2009–2011). The objectives of the study were to evaluate the yield stability of the genotypes and the relative importance of different stability parameters for improving selection in faba bean. The study was conducted using a randomized complete block design with four replications. G × E interaction and yield stability were estimated using 17 different stability parameters. Pooled analysis of variance for grain yield showed that the main effects of both genotypes and environments, and the interaction effect, were highly significant(P ≤ 0.001) and(P ≤ 0.01), respectively. The environment main effect accounted for 89.27% of the total yield variation, whereas genotype and G × E interaction effects accounted for 2.12% and 3.31%, respectively.Genotypic superiority index(Pi) and FT3 were found to be very informative for selecting both high-yielding and stable faba bean genotypes. Twelve of the 17 stability parameters,including CVi, RS, α, λ, S2 di, bi, S(2)i, Wi, σ2i, EV, P59, and ASV, were influenced simultaneously by both yield and stability. They should accordingly be used as complementary criteria to select genotypes with high yield and stability. Although none of the varieties showed consistently superior performance across all environments, the genotype EK 01024-1-2ranked in the top third of the test entries in 61.5% of the test environments and was identified as the most stable genotype, with type I stability. EK 01024-1-2 also showed a17.0% seed size advantage over the standard varieties and was released as a new variety in2013 for wide production and named "Gora". Different stability parameters explained genotypic performance differently, irrespective of yield performance. It was accordingly concluded that assessment of G × E interaction and yield stability should not be based on a single or a few stability parameters but rather on a combination of stability parameters.

文摘Faba bean (Vicia faba L.), one of the most important legumes in the world, evolved different types of cultivars due to its partial cross-pollination. The development of simple sequence repeat (SSR) markers from expressed sequence tags (EST) provided a useful tool for investigation of its genetic diversity. The purpose of the present study was to investigate the genetic diversity of faba bean from China and Europe using EST-SSR markers. 5 031 faba bean ESTs from the NCBI database were downloaded and assembled into 1 148 unigenes. A total of 107 microsatellites in 96 unigenes were identified, indicating that merely 8.36% of sequences contained SSRs. The most abundant SSR within faba bean was tri-nucleotide repeat motif, and among all the tri-nucleotide repeats, the motif AAG/CTT was the most abundant type. Based on these results, 11 EST-SSR markers were used to assess the genetic diversity of 29 faba bean cultivars from China and Europe with two to three alleles per locus. The polymorphism information content value ranged from 0.0644 to 0.4278 with an average of 0.2919. Principal coordinate analysis (PCA) and phylogenetic clustering based on these 11 EST-SSR markers distinguished these cultivars into different groups. The results indicated that faba bean in China had a narrow genetic basis, and the additional sources of genetic cultivars/accessions should be introduced to enhance the genetic variability. The results of this study proved that the EST-SSR marker is very effective in evaluation of faba bean germplasm.

文摘Faba bean(Vicia faba L.) has an important place in the Ethiopian national diet. It is consumed in various forms and contributes to the improvement of soil fertility. However,its production and productivity are affected by biotic and abiotic constraints. Among the biotic constraints, the emerging faba bean gall disease, caused by Olpidium uiciae, is the major and most destructive disease wherever faba bean is grown. Field experiments were conducted at two locations(Farta and Tach Gayint districts) to evaluate the reaction of faba bean varieties to faba bean gall disease and to assess them for yield and yield components during the 2014 and 2015 main cropping seasons. Thirteen faba bean varieties and one local check were plantecd in three replications Lusing a randomized complete block design. The disease incidence and severity of faba bean gall were recorded(on a 1-9 scale) five tinmes at10-day intervals. A combined analysis of variance showed za significant difference(P < 0.05)among faba bean varieties with respect to the incidence and severity of gall disease at both locations. Disease incidence, severity, and AUDPC were lowest for variety Turmsa at both locatiOons, but this variety showed lhigh yield only at tlhe Farta location. 'The lhighest yields were obtained from varieties Degaga(1157.74 kg ha ') and Nc58(828.97 kg ha ') at Farta and Tach Gayint, respectively and these varieties slhowed low faba bean gall severity and AUDPC. Thus, higher-yielding faba bean varieties such as Degaga and Nc58 are recommended for faba bean production areas in northwestern Ethiopia.

文摘To analyze the nutritional composition of faba bean(Vicia faba L.) seed, estimation models were developed for protein, starch, oil, and total polyphenol using near infrared spectroscopy(NIRS). Two hundred and forty-four samples from twelve producing regions were measured in both milled powder and intact seed forms. Partial least squares(PLS) regression was applied for model development. The model based on ground seed powder was generally superior to that based on the intact seed. The optimal seed powder-based models for protein, starch, and total polyphenol had coefficients of correlation(r2) of 0.97, 0.93 and 0.89, respectively. The relationship between nutrient contents and twelve producing areas was determined by two-step cluster analysis. Three distinct groupings were obtained with region-constituent features, i.e., Group 1 of high oil, Group 2 of high protein, and Group 3 of high starch as well as total polyphenol. The clustering accuracy was 79.5%. Moreover, the nutrition contents were affected by seeding date, longitude, latitude, and altitude of plant location. Cluster analysis revealed that the differences in the seed were strongly influenced by geographical factors.

文摘Faba bean(Vicia faba L.)has been identified as a rich source of L-DOPA,which is used in treating Parkinson's disease.Biosynthesis and accumulation of active substances such as L-DOPA in plant tissues may interact with growing conditions and processing methods.Accumulation trends of L-DOPA in various faba bean organs and the effect of drought stress and N fertilization on L-DOPA content were studied in a field and two greenhouse experiments.The influence of various processing methods on L-DOPA content of faba bean tissues was evaluated.The highest L-DOPA content was detected in fresh leaves(22.4 mg g^(-1))followed by flowers,young pods,mature seeds,and roots.Regardless of processing method,L-DOPA concentration in faba bean tissues was significantly reduced when tissues were boiled or dried.Among various methods of processing,freezing had the lowest detrimental effect,reducing L-DOPA concentrations by 24.1%and 21.1%in leaves and seeds,respectively.Drought stress elevated L-DOPA concentration,and maximum L-DOPA(23.3 mg g^(-1)of biomass)was extracted from plants grown under severe drought stress.However,L-DOPA yield(L-DOPA concentration×biomass)was compromised,owing to the adverse influence of drought stress on dry matter production.No significant difference in L-DOPA concentration was detected among various N application rates.

文摘Yield performance in cereal and legume intercropping is related to nutrient management,however,the yield response of companion crops to nitrogen(N)input is inconclusive and only limited efforts have focused on rationed phosphorous(P)fertilization.In this study,two multi-year field experiments were implemented from 2014-2019 under identical conditions.Two factors in a randomized complete block design were adopted in both experiments.In field experiment 1,the two factors included three planting patterns(mono-cropped wheat(MW),mono-cropped faba bean(MF),and wheat and faba bean intercropping(W//F))and four N application rates(N0,0 kg N ha^(-1);N1,90 and 45 kg N ha^(-1) for wheat and faba beans,respectively;N2,180 and 90 kg N ha^(-1) for wheat and faba beans,respectively;and N3,270 and 135 kg N ha^(-1) for wheat and faba beans,respectively).In field experiment 2,the two factors included three P application rates(P0,0 kg P_(2)O_(5) ha^(-1);P1,45 kg P_(2)O_(5) ha^(-1);and P2,90 kg P_(2)O_(5) ha^(-1))and the same three planting patterns(MW,MF,and W//F).The yield performances of inter-and mono-cropped wheat and faba beans under different N and P application rates were analyzed and the optimal N and P rates for intercropped wheat(IW)and MW were estimated.The results revealed that intercropping favored wheat yield and was adverse to faba bean yield.Wheat yield increased by 18-26%,but faba bean yield decreased by 5-21% in W//F compared to MW and MF,respectively.The stimulated IW yield drove the yield advantage in W//F with an average land equivalent ratio(LER)of 1.12.N and P fertilization benefited IW yield,but reduced intercropped faba bean(IF)yield.Nevertheless,the partial LER of wheat(pLER_(wheat))decreased with increasing N application rates,and the partial LER of faba bean(pLER_(faba bean))decreased with increasing P application rates.Thus,LER decreased as N input increased and tended to decline as P rates increased.IW maintained a similar yield as MW,even under reduced 40-50% N fertilizer and 30-40% P fertilizer conditions.The estimated optimum N application rates for IW and MW were 150 and 168 kg ha^(-1),respectively,and 63 and 62 kg ha^(-1) for P_(2)O_(5),respectively.In conclusion,W//F exhibited yield advantages due to stimulated IW yield,but the intercropping yield benefit decreased as N and P inputs increased.Thus,it was concluded that modulated N and P rates could maximize the economic and ecological functions of intercropping.Based on the results,rates of 150 kg N ha^(-1) and 60 kg P_(2)O_(5) ha^(-1) are recommended for IW production in southwestern China and places with similar conditions.
文摘The study was conducted in Al-Qassim region in February 2020 and the study aimed to know the effect of seed size on germination and some morphological parameters in Faba bean (Vicia faba L.) plant, by dividing the seeds into three sizes large 2.5 - 2.3 cm, medium 2.0 - 2.2 cm, and small 1.7 - 1.9 cm and planting them. The results showed that the germination percentage in the large seeds was the highest (100%), and the size of the seeds affected the length of the root and shoot as the large seeds gave the highest length for root (8.37 cm) and shoot (14.2 cm) compared to the medium and small seeds. So, for these results, the seed size is closely related to root and shoot length, number of leaves.
文摘Salinity treatments (NaCl and Na2SO4) reduced plant growth and increased the accumulation of Na^+, P^3+,Fe^3+ , Mn^2+, and CIin root, stem, leaf and legume. The uptake of K^+ reduced in the presence of both salts whereas uptake of Ca^2+ retarded mainly by Na2SO4. Chlorophyll content was affected mainly by NaCl, while Na2SO4 treatment lowered the rate of photosynthetic activity. Both salt compounds caused accumulation of free amino acids including free proline but reduced the protein content in the leaves. The salt tolerance capacity of the broad beans plant in which the observations of the effect of salinity determined by different concentrations of NaCI and Na2SO4 on growth, chloroplast pigments, photosynthetic, free amino acids, free proline, protein and inorganic elements on plants are combined with observations on growth and yield, in order to arrive at a better understanding of their salt tolerance, has been studied and discussed in this paper. The results for the latter only (fruiting stage) are presented.
文摘Faba bean is self- and cross-fertilized species. The consequences of self-fertilization are important factors determining the germplasm management in such species with levels of heterogeneity and heterozygsity. Effects of self-fertilization on floral, yield and yield components characters were evaluated by comparing two levels of selfing, produced in bee-proof cages, in open-pollination at two locations in Sudan. Selfing process results in no significant differences in yield and yield components within each cultivar. Autofertile lines with reduced partial dependence on insects for seed set could be produced. Spatial isolation should be used to maintain the genetic purity of such lines. An alternate strategy for entries multiplication should focus on increasing heterozygosity and the maintenance of cross-fertilization inside the entries to prevent contamination with foreign pollens. Our results follow the previous knowledge on faba bean genetic resources conservation and management.
文摘Faba bean (Vicia faba L) seeds are an important source of plant protein for humans and animals. A total of 15,697 Differentially Expressed Genes (DEGs) with pathway annotation were discovered in RNA-Seq of the faba bean seeds. A total of 75 significant KEGG pathways abundance were discovered and 9 pathways were conserved within all genotypes. 41 significant pathways were found to be partially conserved within comparisons of 2 to 6 pairs of genotypes and 25 significant pathways were unique to single pairs of genotypes. There were 8 specific significant pathways discovered related to the faba bean seed Hydration Capacity trait and 9 specific significant pathways discovered related to the PSbMV seeds staining trait. The DEGs demonstrated the genetic distance between these varieties was confirmed by the breeding pedigree selection information and a PCA graph clearly illustrated the genetic distance within these genotypes.
文摘The aim of this study was to investigate the amount of heterosis and performance of faba bean synthetic cultivars compared to line cultivars under semi-arid conditions. Five inbred lines in at least S6 generation were developed and used to develop F1s hybrid (in all possible combination excluding reciprocal), lines mixtures (Syn-0) and synthetic generations of Syn-1. Evaluation of the entries showed the lines to have high general and specific combining ability, high yield and high average degree of cross-fertilization (0.36);hetrosis relative to mid-parent for yield was 67%. Lines mixture from four inbred lines (Hudeiba/93, Bassabier, Ed-Damar and Shabah) gave the highest yield of 3.40 t/ha for Syn-0 and 3.96 t/ha for Syn-1. Compared to the average yield t/ha of the pure stand of the four lines (3.11 t/ha), the increase in yield of was 9% in sy-0 and 27% in Syn-1. Compared to the individual yield t/ha of the pure stand of the lines, the performance of Syn-0 surpassed that of the individual pure stands of the linesby 14% for Hudiaba/93 and Bassabier and 4% for Ed-Damar and 7% for Shabah, whereas the increase in performance of Syn-1 compared to pure stand of the lines was 32%, 25% and 21%, respectively. The results confirm the previous knowledge on yield increase with successive syn-generations in faba bean due to the effects of heterogeneity and heterozygosity. Such results could be used as a base for an effective breeding program for improvement of yield of faba bean grown under the semi-arid zones.

文摘Owing to the limitation of a large genome size(~13 Gb),the genetic and gene mapping studies on faba bean(Vicia faba L.)are lagging far behind those for other legumes.In this study,we selected three purified faba bean lines(Yundou 8137,H0003712,and H000572)as parents and constructed two F2 populations.These two F2 populations,namely 167 F2 plants in Pop1(Yundou 8137×H0003712)and 204 F2 plants in Pop2(H000572×Yundou 8137),were genotyped using a targeted next-generation sequencing(TNGS)genotyping platform,and two high-density single nucleotide polymorphisms(SNP)genetic linkage maps of faba bean were constructed.The map constructed from Pop1 contained 5103 SNPs with a length of 1333.31 cM and an average marker density of 0.26 cM.The map constructed from Pop2 contained 1904 SNPs with a greater length of 1610.61 cM.In these two F2 populations,QTL mapping identified 98 QTLs for 14 agronomic traits related to the flowers,pods,plant types and grains.The two maps were then merged into an integrated genetic linkage map containing 6895 SNPs,with a length of 3324.48 cM.These results not only lay the foundation for fine mapping and map-based cloning of related genes,but can also accelerate the molecular marker-assisted breeding of faba bean.
文摘Response surface methodology (RSM) was employed to optimize the medium composition and culture conditions for the production of alkaline proteases by Bacillus mojavensis A21 on uncommon substrates: chickpea (CF) and faba bean (FF) flours. A significant positive influence of temperature, CF, FF, incubation time and inoculums size on the protease production was evaluated by Plackett Burman Design. Among these, CF was the most influential factor. The enhancement of protease to 9127 U/ml was achieved with the optimization procedure on the medium composed of (g/l): CF, 40;FF 30, NaCl 2.0;KH2PO4 1;K2HPO4 1;CaCl2, 0.1;MgSO4 0.1. The cultures were conducted for 72 hours with an IS of 2%, at 30°C, an agitation speed of 150 rpm and an initial pH of 8.0. More interestingly, the optimization was accomplished using two cheap and local fermentation substrates, CF and FF, which could result in a significant reduction in the cost of medium constituents. The maximum alkaline protease production was 9127 U/ml after 72 h of incubation and showed 5-fold increase in protease production over the initial level.
文摘The effect of honeybee (Apis mellifera carnica) on yield was investigated in open-pollinated faba bean cultivars and three inbred generations produced from them (once-selfed, twice-selfed, and thrice-selfed). All entries were grown in cages under two pollination conditions: presence of bees (cross-pollination) or absence of bees (self-pollination). The open-pollinated generations gave the highest performance in the presence and absence of bees. In the presence of bees, the open-pollinated and their inbred entries gave higher performance in all of the studied traits than in the absence of bees;the average improvement in yield and its components was 22%. The highest improvement percentage in yield performance was shown by more inbred entries (thrice-selfed > once-selfed), indicating that in faba bean populations, the performance of inbred generations was chiefly associated with the tripping of flowers, which is usually governed by successfully fertilized flowers, i.e., plants result from selfing in faba bean population needs to be visited by pollinating insects (bees) to set more seeds. It concluded that honeybee has an important role in increasing faba bean yield in semi-arid conditions;hence, it is important to provide a pollinator friendly environment for their foraging places and nesting sites to secure food supply.
文摘A two-year study was carried out at the Agricultural Experiments and Research Station, Faculty of Agriculture, Cairo University, Giza, Egypt, during 2015/2016 and 2016/2017 seasons to evaluate seed yield and quality of two faba bean cultivars to different rates of amino acids compounds under narrow and wide ridges. Two faba bean cultivars Sakha 1 and Masr 3 were grown in two ridge widths 60 and 120 cm and received five rates of amino acids compounds (Power mix at rates 1.5 cm⋅L−1 “Pm1” and 3.0 cm⋅L−1 “Pm2”, Super mix at rates of 3.5 cm⋅L−1 “Sm1” and 7.0 cm⋅L−1 “Sm2”, as well as, water only “control treatment”). The treatments laid out in a split split plot distribution in randomized complete blocks design in three replications were used. Ridge width was randomly assigned to the main plots, faba bean cultivars were allocated in sub-plots and amino acids compounds were allocated in sub sub-plots. Shoot chemical composition and photosynthesis pigments, as well as, chemical composition in seed traits of faba bean were tested in the laboratories of Plant Physiology Section, Agricultural Botany Department, Faculty of Agriculture, Cairo University, Giza, Egypt. Wide ridge had higher nitrogen (N), phosphorus (P), potassium (K), total sugars and total free amino acids concentrations in faba bean shoot and seeds in addition to chlorophyll a (Chl a) and chlorophyll b (Chl b) in faba bean shoot, as well as, most seed yield attributes than those of the narrow one. Faba bean cultivar Sakha 1 had higher values of seed yield, yield attributes and quality than Masr 3 that achieved higher seed antioxidants. Also, amino acids compounds affected significantly all studied traits of faba bean plants. Pm2 recorded the highest values of chemical composition in faba bean shoot and seeds. Moreover, Pm2 gave the highest seed yield and yield attributes compared to others. The interaction between ridge width and faba bean cultivar was significant for total sugars and carotenoids concentrations in faba bean shoot and 100-seed weight, as well as, seed N content. Also, the interaction between ridge width and amino acids compound had significant effects on shoot and seed N, P, K concentrations, number of pods plant−1 and seed yield ha−1, as well as, total soluble phenols and total free amino acids concentrations. Moreover, the interaction between faba bean cultivar and amino acids compound had significant effects on shoot Chl a and b concentrations, number of seeds pod−1 and seed yield plant−1, as well as, seed N, total soluble phenols and total free amino acids concentrations. Wide ridge x faba bean cultivar x amino acids compound interaction had significant effects on photosynthesis pigments, number of seeds pod−1 and seed yield ha−1, as well as, seed N, total sugars, total soluble phenols and total free amino acids concentrations. High seed yield and quality were recorded by growing faba bean cultivar Sakha 1 in wide ridge with foliar spraying at rate of 3.0 cm⋅L−1 of power mix. On the other hand, growing faba bean cultivar Masr 3 in narrow ridge with foliar spraying at rate of 3.5 cm⋅L−1 of super mix had good antioxidants in faba bean seeds.
文摘A field experiment was conducted at El-Serw Agricultural Research Station, Damietta Governorate, Egypt during 2016/2017 and 2017/2018 seasons to reduce mineral N inputs of sugar beet with increased land use efficiency and profitability under intercropping conditions. Seven treatments included five treatments (90 kg nitrogen “N” + 30 m3 farm yard manure “FYM”/fad, 80 kg N +30 m3 FYM/fad, 70 kg N +30 m3 FYM/fad and 400 g of Cerealine + 30 m3 FYM/fad for intercropping faba bean cultivar Spanish with sugar beet cultivar Gloria) and two treatments (90 and 20 kg N/fad for solid culture of sugar beet and faba bean, respectively, as recommended mineral N fertilizer rate) were compared in a randomized complete block design with three replications. Solid culture of sugar beet with the application of recommended rate (90 kg N/fad) gave the highest top, root and sugar yields/fad, as well as the percentage of purity compared with the other treatments in both seasons. Intercropping faba bean with sugar beet plants with application of 90 kg N + 30 m3 FYM/fad gave the highest number of leaves/plant, leaf area/plant, root length, root diameter and root weight/plant followed by intercropped sugar beet plants that fertilized with 80 kg N + 30 m3 FYM/fad compared with the other treatments in both seasons. On the other hand, intercropped sugar beet that received 400 g of Cerealine + 30 m3 FYM/fad had the highest percentages of T.S.S. and sucrose followed by 70 kg N + 30 m3 FYM/fad compared with the other treatments in both seasons. Solid culture of faba bean with the application of 20 kg N/fad gave the highest plant height, number of seeds/pod and seed yield/fad, meanwhile the highest number of branches/plant and pod length were achieved by intercropping faba bean with sugar beet with application of 90 kg N + 30 m3 FYM/fad followed by intercropped faba bean plants that fertilized with 80 kg N + 30 m3 FYM/fad compared with the other treatments in both seasons. However, intercropped faba bean plants that fertilized with 70 kg N + 30 m3 FYM/fad gave the highest number of pods per plant, number of seeds per pod, seed index and seed yield per plant compared with the other treatments in both seasons. Land equivalent ratio (LER), land equivalent coefficient (LEC) and relative crowding coefficient (RCC) were high by intercropping faba bean with sugar beet with the application of 80 kg N + 30 m3 FYM/fad indicating yield advantage was achieved. The value of aggressivity (Agg) of sugar beet was negative for all combinations indicating that sugar beet is dominated component in the present study. Intercropping faba bean with sugar beet with the application of 80 kg N + 30 m3 FYM/fad achieved higher total income and monetary advantage index (MAI) than the other treatments. Growing sugar beet plants in both sides of beds (1.2 m width) with one faba bean row in middle of sugar beet beds with the application of 80 kg N + 30 m3 FYM/fad decreased mineral N fertilizer rate by 10.00% of the recommended sugar beet mineral N fertilizer rate, as well as increased land usage and profitability for Egyptian farmers compared with sugar beet solid culture.
