Characterization of Seed Storage Proteins in Eight Bambara Groundnut Landraces in Burkina Faso

The Bambara groundnut Vigna subterranea (L.) Verdc. is a drought-resistant indigenous African grain legume with significant nutritional and agronomic potential. This study aimed to characterize the seed storage proteins of eight Bambara groundnut landraces. Seeds of Bambara groundnut landraces were collected from local markets in Burkina Faso, and total soluble protein as well as protein fractions were extracted. Crude protein content was determined by the Kjeldahl method, and soluble proteins were quantified using Bradford dye binding assay. The average crude protein content of the seeds was found to be 18.46%, with variations ranging from 17.69% to 19.17% among the different landraces. Most of the protein content was soluble, constituting approximately 87.04% of the total crude protein. Albumin fraction was the most dominant, representing about 95.42% of the total soluble proteins. The globulin, prolamin and glutelin fractions accounted for 1.82%, 0.13% and 1.17% of the soluble proteins, respectively. The findings provide valuable insights into the protein composition of Bambara groundnut landraces and contribute to our understanding of its nutritional potential, laying the groundwork for further research on crop improvement and sustainable agriculture practices.

A Farmer’s Approach to Detecting Photoperiod Sensitivity in Rice (Oryza sativa ssp. indica) Landraces

Most indigenous rice landraces are sensitive to photoperiod during short day seasons,and this sensitivity is more pronounced in indica than in japonica landraces.Attempts to identify photoperiod sensitive(PPS)cultivars based on the life history stages of the rice plant,and several models and indices based on phenology and day length have not been precise,and in some cases yield counterfactual inferences.Following the empirical method of traditional Asian rice farmers,the author has developed a robust index,based on the sowing and flowering dates of a large number of landraces grown in different seasons from 2020 to 2023,to contradistinguish PPS from photoperiod insensitive cultivars.Unlike other indices and models of photoperiod sensitivity,the index does not require the presumed duration of different life history stages of the rice plant but relies only on the flowering dates and the number of days till flowering of a rice cultivar sown on different dates to consistently identify photoperiod sensitive cultivars.

Diversity of Flower Opening Time and Duration in Rice (Oryza sativa ssp. indica) Landraces of South and Southeast Asia in Different Cultivation Seasons

Different cultivars of rice(Oryza sativa)open at different times of the day,and the overlap of anthesis time in rice between the neighbouring cultivars is of crucial importance to the degree of cross pollination in rice.Nevertheless,none of the past experiments with cross pollination between different rice cultivars ever reported the respective flower opening time(FOT)and flower exposure duration(FED)of the parent cultivars,until recently.The authors present here the first record of FOT and FED of 1114 indica rice landraces of South and Southeast Asia,growing during sum-mer and winter seasons in three consecutive years.The authors also present an analysis of the influences of the grow-ing season on the anthesis behaviour,and present the first records of the FOT and FED variability on sunny and cloudy days of a large number of landraces.The data show that rice florets tend to open later in the morning(that is,take longer time to anthesis after sunrise)on sunny days than on cloudy days,and also significantly later during long day seasons(spring and summer)than during short day season(winter);and that FED is inversely related to both FOT and the length of duration from sunrise to first flower opening.The wide ranges of FOT(8:50 a.m.to 12:40 p.m.)and FED(15 to 194 minutes)also suggest the ample time window for receiving pollen from neighbouring cultivars with differ-ent FOT,enhancing the chances of cross pollination between hundreds of rice landraces with FOT and FED overlaps.

The Effects of Low Phosphorus Stress on Morphological and Physiological Characteristics of Maize (Zea mays L.) Landraces

A field trial was conducted to investigate main morphological and physiological changes of different maize landraces to low-P stress at the stage of seedling. P-deficiency significantly decreased root volume, total leaf area, and plant dry weight, but greatly increased density of root hairs and root top ratio. In addition, P-deficiency induced the significant enhancement of phosphorus utilization efficiency and the amount of proline, malondialdehye （MDA）, acid phosphatase （APase）, peroxidase （POD） and superoxide dismutase （SOD）, but the significant reduction of P uptake and soluable protein content. Since P-deficiency had smaller effects on the P-tolerant maize landraces DP-44, DP-32 and DP-33 as compared with P-sensitive landraces DP-29 and DP-24, it was demonstrated that differences of tolerance to P-deficiency existed among different maize landraces. The results based on the correlation analysis showed that the economic yield of maize landraces had relationships with their morphological and physiological characteristics under P-deficiency.

Phenotypic diversity in Ethiopian durum wheat(Triticum turgidum var.durum)landraces

The phenotypic diversity of 274 Ethiopian durum wheat accessions was analyzed, taking their geographic origins into account. The aim was to assess the extent and patterns of agronomically important phenotypic variation across districts of origin and altitude classes for major qualitative traits using diversity index and multivariate methods. Eight qualitative and three quantitative traits were scored for 2740 plants and analyzed for diversity. The Shannon–Weaver diversity(H′) index was used to estimate phenotypic diversity. The estimated H′ ranged from monomorphic for glume hairiness to highly polymorphic for other traits. The highest(0.86) H′ was obtained for seed degree of shriveling, possibly indicating the differential responses of the genotypes to water deficit during later growth stages. With respect to district of origin, the highest(0.72) and lowest(0.44) H′ values were obtained for the Bale and SNNP districts, respectively. With respect to altitude, the highest(0.76) and lowest(0.62) H′ values were recorded for altitudes 1600–2000and > 3000 m above sea levels, respectively. Principal components analysis explained substantial variation contributed by district of origin and altitude range. Genotypes were clustered into three groups by districts of origin and altitude class, with relatively strong bootstrap values of 57 and 62 for the former and latter, respectively. It could be concluded that Ethiopian durum wheat landraces are very diverse both within and among districts of origin and altitude classes. This wealth of genetic diversity should be exploited for wheat improvement of yield and for resistance to biotic and abiotic stresses, particularly terminal drought.

Analysis of Genetic Diversity and Population Structure of Maize Landraces from the South Maize Region of China

Understanding genetic diversity and population structure of landraces is important in utilization of these germplasm in breeding programs. In the present study, a total of 143 core maize landraces from the South Maize Region （SR） of China, which can represent the general profile of the genetic diversity in the landraces germplasm of SR, were genotyped by 54 DNA microsatellite markers. Totally, 517 alleles （ranging from 4 to 22） were detected among these landraces, with an average of 9.57 alleles per locus. The total gene diversity of these core landraces was 0.61, suggesting a rather higher level of genetic diversity. Analysis of population structure based on Bayesian method obtained the samilar result as the phylogeny neighbor-joining （N J） method. The results indicated that the whole set of 143 core landraces could be clustered into two distinct groups. All landraces from Guangdong, Hainan, and 15 landraces from Jiangxi were clustered into group 1, while those from the other regions of SR formed the group 2. The results from the analysis of genetic diversity showed that both of groups possessed a similar gene diversity, but group 1 possessed relatively lower mean alleles per locus （6.63） and distinct alleles （91） than group 2 （7.94 and 110, respectively）. The relatively high richness of total alleles and distinct alleles preserved in the core landraces from SR suggested that all these germplasm could be useful resources in germplasm enhancement and maize breeding in China.

A Comparative Analysis of B Chromosomes and Genetic Diversity in Maize (Zea mays L.) Landraces from Southwest China

The number of B chromosomes （Bs） in 54 maize landraces from Southwest China was tested by means of cytological observations. Nine landraces with Bs were observed. A map, showing the geographic distribution of the landraces with Bs, was plotted. It was found that southeastern Sichuan Province in China was the main distribution area of the landraces with Bs in Southwest China. In order to obtain information on relationships between Bs and genetic variation, genetic diversity both among and within 11 landraces was evaluated. For each SSR marker, the number of alleles ranged from 3 to 12 with an average of 7.86, which revealed a high level of genetic diversity among maize landraces in Southwest China. Based on SSRs data, higher genetic variation was found in the landraces with 2B, and the genetic distance between the landraces with and without Bs was higher. The results together with the principal component analysis （PCA） supported the hypothesis that maize landraces in Southwest China were first introduced to the middle part of southwest Sichuan, China. At the same time, the effect of Bs on genetic variation was discussed.

Waxy allele diversity in waxy maize landraces of Yunnan Province, China

Waxy maize is one of the main fresh-eating maize types,and a mutation of the waxy gene causes the waxy character of maize grains.China is rich in waxy maize landraces,and Yunnan and its surrounding areas,are the place of origin and genetic diversity center of Chinese waxy maize.The six known waxy alleles of Chinese waxy maize are wx-D7,wx-D10,wx-Cin4,wx-124,wx-Reina,and wx-Xuanwei.The mutation sites of these alleles all occur in the coding region of the waxy gene,however,the mechanism by which the waxy characteristic is caused by the mutation in the regulatory region has only been reported rarely in maize.In this study,405 waxy maize landraces from Yunnan were used as materials to identify the insertion and deletion of a large sequence fragment in the upstream~3.5 kb regulatory region of the waxy gene by molecular marker detection.Three different waxy alleles were identifed in this study:wx-PIF/Harbinger,wx-hAT and wxElote2.These three types of mutations all represented transposons inserted into the regulatory region of the waxy gene.Wx-PIF/Harbinger was a 304-bp MITE class transposon insertion belonging to the PIF/Harbinger family,while wx-hAT was a 560-bp MITE class transposon insertion belonging to the hAT family,and wx-Elote2 was a 6560-bp LTR-like transposon insertion.In this study,the alleles were identifed for more than 70%of the waxy maize landraces in Yunnan,which provids a basis for the utilization of these waxy maize landraces.

Evaluation of Genetic Diversity of Sichuan Common Wheat Landraces in China by SSR Markers

Genetic diversity of 62 Sichuan wheat landraces accessions of China was investigated by agronomic traits and SSR markers. The landrace population showed the characters of higher tiller capability and more kernels/spike, especially tiller no./plant of six accessions was over 40 and kernels/spike of three accessions was more than 70. A total of 547 alleles in 124 polymorphic loci were detected with an average of 4.76 alleles per locus by 114 SSR markers. Parameters analysis indicated that the genetic diversity ranked as genome A 〉 genome B 〉 genome D, and the homoeologous groups ranked as 5〉4〉3〉1〉2〉7〉6 based on genetic richness （Ri）. Furthermore, chromosomes 2A, 1B and 3D had more diversity than that of chromosomes 4A, 7A and 6B. The variation of SSR loci on chromosomes 1B, 2A, 2D, 3B, and 4B implied that, in the past, different selective pressures might have acted on different chromosome regions of these landraces. Our results suggested that Sichuan common wheat landraces is a useful genetic resource for genetic research and wheat improvement.

Multienvironmental evaluation of wheat landraces by GGE Biplot Analysis for organic breeding

This study was conducted to determine the performance of wheat landraces cultivated under organic conditions and to analyze their stability across diverse environments. Six wheat landraces with specific characteristics (high protein content, drought tolerance, stay green) were tested under organic growing environment. The experiments were applied in three locations (Larisa (LAR), Thessaloniki (THES), Kilkis (KIL)) for three growing seasons. The role of specific agronomic traits (stay green, lodging) and their correlation with yield components were analyzed. Stability and genotypic superiority for grain yield were determined using ANOVA and genotype × environment (GGE) biplot analysis. Furthermore, the interrelationships among wheat traits and genotype-by-trait using regression analysis, coefficient of variation and (GT)-biplot technique were studied. Significant differences were found in yield among wheat landraces tested, and also in yield components, as related to specific traits expressed into organic environment. Best varieties in terms of yield were the medium statured landraces Skliropetra and M. Argolidas, characterized by lowest weight of 1000 grains, large number of spikes per m2 meter and the highest number of grains per spike as compared to the other landraces. The statistical model GGE biplot provides useful information for experimentation of wheat landraces when grown under organic environment. It identifies clearly the ideal and representative environment for experimentation and underlines the effect of specific traits for each wheat cultivar on yield performance and stability across environments.

Validation of the Red Pericarp Gene from 419 Rice Landraces in Guangxi via Genome-wide Association Studies

Rice has different colors of pericarp, such as red, white and black. Red rice pericarp is rich in proanthocyanins, which have antioxidant properties and are beneficial to human health. In the present study, we analyzed the red-pericarp gene Rc of 419 rice landraces in Guangxi by genome-wide association study （GWAS）, and validated that the Rc gene regulated the red periearp trait in flee. By analyzing the genomie DNA of 97 red-pericarp flee eultivars, we identified two new alleles in C139 and C323. Then, the exons of Rcc＇9 and Rcc were sequenced with Sanger method, and the results demonstrated that the natural mutations within Re ene resulted in the two alleles Rcc and Rcc.

Field evaluation of durum wheat landraces for prevailing abiotic and biotic stresses in highland rainfed regions of Iran

Biotic and abiotic stresses are major limiting factors for high crop productivity worldwide. A landrace collection consisting of 380 durum wheat(Triticum turgidum L. var. durum) entries originating in several countries along with four check varieties were evaluated for biotic stresses:yellow rust(Puccinia striiformis Westendorf f. sp. tritici) and wheat stem sawfly(WSS) Cephus cinctus Norton(Hymenoptera: Cephidae), and abiotic stresses: cold and drought. The main objectives were to(i) quantify phenotypic diversity and identify variation in the durum wheat landraces for the different stresses and(ii) characterize the agronomic profiles of landraces in reaction to the stresses. Significant changes in reactions of landraces to stresses were observed.Landraces resistant to each stress were identified and agronomically characterized.Percentage reduction due to the stresses varied from 11.4%(yellow rust) to 21.6%(cold stress) for 1000-kernel weight(TKW) and from 19.9(yellow rust) to 91.9%(cold stress) for grain yield. Landraces from Asia and Europe showed enhanced genetic potential for both grain yield and cold tolerance under highland rainfed conditions of Iran. The findings showed that TKW and yield productivity could be used to assess the response of durum wheat landraces to different stresses. In conclusion, landraces showed high levels of resistance to both biotic and abiotic stresses, and selected landraces can serve in durum wheat breeding for adaptation to cold and drought-prone environments.

Vegetative Compatibility and Virulence Diversity of Verticillium dahliae from Okra (Abelmoschus esculentus) Plantations in Turkey and Evaluation of Okra Landraces for Resistance to V. dahliae

Forty-four V.dahliae isolates were collected from symptomatic vascular tissues of okra plants each from a different field in eight provinces located in the eastern Mediterranean and western Anatolia regions of Turkey during 2006-2009.Nitrate-nonutilizing(nit)mutants of V.dahliae from okra were used to determine heterokaryosis and genetic relatedness among isolates.All isolates from okra plants were grouped into two vegetative compatibility groups(VCGs)(1 and 2)and three subgroups as 1A(13.6%,6/44),2A(20.5%,9/44)and 2B(65.9%,29/44)according to international criteria.Pathogenicity tests were performed on a susceptible local okra(A.esculentus)landrace in greenhouse conditions.All isolates from VCG1A and VCG2B induced defoliation(D)and partial defoliation(PD)symptoms,respectively.Other isolates from VCG2A gave rise to typical leaf chlorosis symptoms without defoliation.The obtained data showed that the virulence level of V.dahliae isolates from okra was related to their VCG belongings.Eighteen okra landraces from diverse geographical origins were screened for resistance to VCG2B and VCG1A of V.dahliae.The results indicated that all landraces were more susceptible to highly virulent VCG1A-D pathotype displaying D or PD symptoms depending on their susceptibility levels with a mean disease severity index of 3.52 than to less virulent VCG2B-PD pathotype of V.dahliae displaying PD and ND symptoms with a mean disease severity index of 2.52.Significant differences were observed among the landraces;however,none of them exhibited a level of resistance.Okra landraces;Çorum,Hatay Has and Sanlıurfa displayed the lowest level of susceptibility or little tolerance to both D and PD pathotypes.VCG2B of PD was prevailing in the surveyed areas and VCG1A of D was the most virulent of the VCGs identified.Introduction of resistant genotypes to Turkish okra germplasm from different sources and breeding new resistant okra cultivars are critical for the sustainability of okra production.

Preliminary Study on the Quality Difference of Local Broad-shoulder Bitter Gourd Landraces in Foshan

[Objectives]The study aims to provide important reference for the breeding and research of new varieties of functional broad-shoulder bitter gourd.[Methods]8 pure varieties of local broad-shoulder bitter gourd landraces in Foshan were used as experimental materials,in which polysaccharide,cellulose and vitamin C content were measured.[Results]Among the 8 varieties of local self-selected broad-shoulder bitter gourd in Foshan,the polysaccharide content of Foxuan 6 was the highest,up to 113.78 mg/100 (g·FW),which was significantly higher than that of the other 7 varieties.The polysaccharide content of Foxuan 2 was the lowest.The cellulose content of Foxuan 8 was the highest,reaching 24.50 mg/100 (g·FW),which was significantly higher than that of the other 7 varieties.The cellulose content of Foxuan 4 was the lowest.The vitamin C content of Foxuan 5 was the highest,reaching 74.24 mg/100 (g·FW),which was significantly higher than that of the other 7 varieties.The vitamin C content of Foxuan 4 was the lowest,only 7.05 mg/100 (g·FW).In a word,there were big differences between the 8 varieties of broad-shoulder bitter gourd in terms of polysaccharide,cellulose and vitamin C content.[Conclusions]It is possible to make full use of their own quality differences and develop new varieties of functional broad-shoulder bitter gourd by means of cross combination.

Association Analysis of Quantitative Traits in F_1 Families Derived from Two Maize Landraces

[ Objective] The objective of this study was to evaluate the genetic diversity and characterization of special maize population consisting of 135 Fl fami- lies. [ Method ] In this study, association analysis was conducted in 135 F1 families derived from two maize landraces, and the efficiency of this method was evalua- ted through simulation. [ Result] Association analysis with different kinds of families showed that large population size and robust phenotypic data were required for association mapping. For all the phenotypic traits, the model controlling beth population structure and relative kinship （ Q ＋ K） performed better than the model controlling relative kinship （K）, and similarly to the model controlling population structure （Q）. Across 100 simulation runs in QULINE, the average power of QTL detection for the two models were 88.64% and 83.64% respectively, and the number of false QTL was reduced from 399 with GLM model to 199 with K mod- el. Our simulation results suggested that these F1 families can be used for association analysis, and the power of the QTL detection was related to the maximum al- lele frequency （MAF）and the phenotypic variation （PVE） explained by QTL. [ Conclusion] The results from this study suggest that association analysis using the F1 families is an effective approach to study maize landraces for discovering elite genes which we are interested in from these special populations.

Using Bayesian and Eigen approaches to study spatial genetic structure of Moroccan and Syrian durum wheat landraces

The Mediterranean durum wheat landraces are genetically diverse and important sources for improving resistance to abiotic and biotic stresses and developing adapted and productive durum wheat varieties in the Mediterranean region. To study the diversity two distant countries (MoroccoandSyria) durum landraces were studied. Fifty-one microsatellites were used as molecular markers tool to determine the genetic structure and spatial adaptation of these landraces. We used two spatially-explicit methods (Bayesian and Eigen) to determine the genetic diversity and structure of a population composed of Moroccan (98) and Syrian (90) durum wheat landraces. Non-spatial methods were also applied for comparison. A significant genetic difference was detected between the landraces originated from Morocco and Syria. Six subpopulations were revealed for each country using the Bayesian method and the Eigenanalysis, which generated PC1 and sPC1, showed similar structure. Eigenanalysis exhibited a significant global genetic structure for both countries landraces;and showed that neighboring landraces tend to have close genetic profile. The two first axes of PC1 and sPC1 had discriminated four out of the six subpopulations revealed by the Bayesian methodology. Also, our study detected the close relationship between the durum landraces from the coastal areas of Syria and the Moroccan landraces from the Atlantic coastal regions where the Phoenicians/Carthaginians had settled in Morocco. These results demonstrate the importance of using the spatial models in genetic analysis of durum wheat landraces;and also recommend the use of the easily usable Eigenanalysis to analyze the genetic diversity and structure.

Screening for Drought-Tolerant and Low-Input Responsive Upland Rice Landraces

Productivity potentials of upland rice landraces (URLs) are continuously compromised by scanty water supply due to competing priorities for irrigations and fluctuations in agro-ecological conditions peculiar to low-input farming systems. A growing demand for rice amidst decline in productive agricultural areas plunges into an urgent contribution of marginal areas critical in attaining food sufficiency among Filipino households. Agronomic performances of URLs locally found in Catanduanes province, Philippines were evaluated in a replicated trial utilizing three URLs: Kamanang [1], Kadari [2] and Bulaw [3]. The experimental set-up was closely monitored for consistent dry moisture content and zero fertilizer application. Results were significant for traditional upland landraces: Kamanang and Kadari, scored in terms of higher germination rate, increment plant height and the number of tillers during the vegetative stage. Leaf color gradations, although statistically not significant across cultivars, were suggestive of varying adaptive performance between traditional cultivars subjected to low-input system. Putative low-input responsive lines indicated by the higher survival percentage and overall agronomic responses were selected from the study site. Screened lines took part of the advance population which would be potentially able to tolerate poor soil conditions (i.e. poor storehouse of water and nutrients) especially in areas with edaphological constraints and changing rainfall distribution pattern. The development of putative drought tolerant lines among URLs forms the most economical solution implicated to areas with limited access to agricultural interventions.

Genetic Diversity in a Collection of Chinese Sorghum Landraces Assessed by Microsatellites

Genetic diversity was characterized in a collection of 159 sorghum (Sorghum bicolor L. Moench) landraces gathered from the colder region (primarily the northeastern region) of China. A set of 41 microsatellites or simple sequence repeat (SSR) markers distributed throughout the 10 chromosomes of sorghum was utilized in the analysis. Majority (40 out of 41 SSRs, 98%) of the SSR markers were polymorphic and highly informative with polymorphism information content (PIC) value ranging from 0.05 to 0.92. An estimation of genetic similarity coefficients (GSC, with values ranging from 0.42 to 0.96) revealed a range of variability in this collection of sorghum landraces. Eight clusters of accessions were identified at a cut off at 0.50 GSC and these groupings were supported by the analysis of subpopulations using Structure. This study provides evidence that Chinese landraces of sorghum exhibit moderate genetic diversity and results from cluster analysis may well aid in identification of diverse accessions that can serve as parental lines for efficient utilization and application of these germplasm into sorghum breeding programs.

Brazilian Maize Landraces Silks as Source of Lutein: An Important Carotenoid in the Prevention of Age-Related Macular Degeneration

The carotenoid composition of the silk tissue of Zea mays (L.) has not been investigated despite its large occurrence in maize grains. For the purpose of evaluating maize silk as a source of carotenoids, samples from eight landraces developed and cultivated in Southern Brazil were assayed. The silk samples were harvested from individual plants through the fourth and seventh day after they emerged, frozen in liquid N2, and lyophilized. The carotenoids were extracted with a MeOH/toluene solution (1:1, v/v), 30 min, and saponified (15% KOH, 12 h, 40℃). The RP-HPLC-UV-visible analysis revealed lutein as the main carotenoid (88.75%) in maize silks, with a wide range of contents (dry weight), i.e. 39.11 ?g?g-1 (Palha Roxa 18) to 176.12 ?g?g-1 (Língua de Papagaio) among the studied genotypes. Smaller amounts of trans-β-carotene, α-carotene, and zeaxanthin were also detected. The results revealed that in parallel to the claimed high genetic variability of maize landraces, a quite variable carotenoidic composition of silk tissue seems to occur in the germoplasm cultivated in Southern Brazil. Taking into account the usage of lutein for the prevention of several pathologies, especially the age related macular degeneration, some maize landraces (e.g. Língua de Papagaio and Rosado) might be interesting sources of a lutein-rich extract that could add value to an underutilized biomass.

GGE Biplot Analyses for Grain Quality and Yield of Durum Wheat (Triticum turgidum ssp. durum Desf.) Landraces Populations

The aim of this study was to determine the GY (grain yield) and some quality characters of durum wheat landraces under Thrace Region ecological conditions. This study was carried out in randomized complete blocks design with three replications in the locations of Tekirdag, Edirne, Klrklareli and Lüleburgaz during the growing years of 2009 and 2010. In the research, 20 durum wheat landraces obtained from different regions of Turkey and 5 obsolete durum wheat cultivars were used as the experimental material. It was determined that the GY, TW (test weight) and PC (protein content) in the first year were higher than the second year in this study. The highest values for GY, TGW (thousand grain weight), and TW and GVR (grain vitreousness rate) were determined in Tekirdag location, while the highest PC was determined in Edirne location. The results of the research showed that GY varied between 321.17-470.33 kg da^-1 in Tekirdag, 301.33-404.00 kg da^-1 in Edirne;197.50-334.67 kg da^-1 in K?rklareli and 280.00-501.33 kg da^-1 in Lüleburgaz. TGWs were determined between 38.17-44.50 g of Tekirdag, 36.00-43.00 g of Edirne, 38.43-43.67 g of Karklareli and 35.33-45.67 g of Lüleburgaz. TW of Tekirdag, Edirne, Karklareli and Lüleburgaz locations changed between 74.67-79.33 kg hl^-1, 69.33-76.83 kg hl^-1, 70.00-75.17 kg hl^-1 and 71.00-77.50 kg hl^-1, respectively. The GVR was determined among 85.00-96.83% in Tekirdag, 68.33-93.33% in Edirne, 67.83-93.83% in Klrklareli, and 85.17-98.17% in Lüleburgaz. The PC of grains was measured among 13.32-14.95% in Tekirdag, 14.90-16.25% in Edirne, 14.27-16.17% in K?rklareli, and 13.40-16.53% in Lüleburgaz. It was determined that Dicle and Dicle-13 landraces for GY and TW, Adlyaman landrace for TGW,Canakkale and Akbugday landraces for the GVR, and Iskenderun, Akbu?day, Erzincan landraces for PC have the highest values.
