An analytic hierarchy process(AHP)was employed to assess the applicability of 18 new and superior varieties of flowers in Hefei City flower border applications.A total of 12 indicators were selected from three distinct aspects of adaptability,ornamental characteristics and use traits,in order to establish a comprehensive evaluation model.The results demonstrate that grade I(J≥2.685)exhibits excellent application value,encompassing six species of plants,such asHydrangeamacrophylla‘Endless Summer’;grade II(2.684≤J≤2.420)is also of notable application value,encompassing five species of plants,such asCallistemonrigidus;grade III(2.419≤J≤2.615)is of average application value,including five species of plants,such asCrocosmiacrocosmiflora;grade IV(J≤2.16)is of relatively poor application value.The evaluation results may be utilized as a theoretical reference for the promotion of new and superior varieties in the flower border of Hefei. 展开更多

Based on the results of the national regional trail for winter rapeseed in four groups,including the upper reaches,middle reaches and lower reaches of Yangtze River and Huang-Huai region in the past twenty years,new varieties of winter rapeseed showed upward trend in average yield,the yield level in Huang-huai group was higher than other groups.The changes of average effective pods per plant were not significant in any group,but the number of grain per pod and 1 000-grain weight showed increase trend.However,the increment of grains per pod in three Yangtze River groups was higher than that in Huang-Huai River group,while the increment of 1 000-grain weight was just opposite.The incidence rate of Sclerotinia sclerotiorum and viral disease in new varieties of winter rapeseed obviously decreased,and the incidence rate of S.sclerotiorum decreased lower than 5%.Genetic improvement for winter rapeseed should be focus on the number of grain per pod and 1 000-grain weight in the future,and yield level of new varieties in all four groups is expected to increase. 展开更多

Boehmeria nivea var.strigosa Zeng Y.Wu&Y.Zhao,a new variety of B.nivea(Urticaceae)from Southwest China,is here described based on evidence from morphology and molecular phylogeny.This new variety is mainly characterized by its green abaxial leaf blade,partly connate stipules,and densely patent strigose hairs on stems and potioles.The phylogenetic analysis based on rbc L,nrDNA and rbc L+nrDNA datasets,revealed that all individuals of B.nivea var.strigosa formed a monophyletic group.The conservation status of B.nivea var.strigosa is assessed as“Near Threatened”(NT)according to IUCN evaluation criteria.The discovery of this new variety is not only crucial for the taxonomy of ramie,but also provides reference for the exploration and utilization of ramie. 展开更多

To enhance the yield potential of an elite indica rice cultivar,an introgression(BC_3-derived) line of IR64,YTH288,was developed using a new-plant-type cultivar,IR66215-44-2-3,as a donor parent.YTH288 has agronomically valuable characteristics such as large panicles,few unproductive tillers,and large leaves inherited from NPT.To identify the genetic basis of these traits,we used 167 F_2 plants derived from a cross between IR64 and YTH288 to conduct QTL analysis for five agronomic traits:days to heading(DTH),culm length(CL),flag leaf length(FLL),flag leaf width(FLW),and filled spikelet number per panicle(FSN).Six putative QTL were detected:four on chromosome4(for CL,FLL,FLW,and FSN) and two on chromosome 2(for DTH and FLL).All QTL with the IR66215-44-2-3 allele,except that for FLL on chromosome 2,had positive effects on each trait.To confirm the effects of these putative QTL,we developed NILs with the IR64 genetic background by marker-assisted selection.We observed significant differences in several agronomic traits between IR64 and NILs that carried these QTL on chromosomes2 and 4.Additionally,four IR64-NILs carrying chromosomal segments derived from different NPT varieties on the long arm of chromosome 4 exhibited similar pleiotropic To enhance the yield potential of an elite indica rice cultivar, an introgression(BC3-derived) line of IR64, YTH288, was developed using a new-plant-type cultivar,IR66215-44-2-3, as a donor parent.

To confirm the effects of these putative QTL, we developed NILs with the IR64 genetic background by marker-assisted selection. We observed significant differences in several agronomic traits between IR64 and NILs that carried these QTL on chromosomes2 and 4. Additionally, four IR64-NILs carrying chromosomal segments derived from different NPT varieties on the long arm of chromosome 4 exhibited similar pleiotropiceffects for unique agronomic traits. These NILs can be used as research materials for studying each trait and as breeding materials for yield improvement of indica rice cultivars. 展开更多

The Convention for the Protection of New Varieties of Plants has 1961/1972 Act ,1978 Act and 1991 Act. China is member of UPOV and its regulations of protection of new varieties of plants conform to 1978 Act. At present, there is big debate whether China accedes to 1991 Act. This paper mainly discussed advantages and possibilities that China accedes to 1991 Act, and concluded that it is highly desirable that China should consider acceding to 1991 Act in order to contribute to development of system on protection of new varieties of plants. 展开更多

[Objective] This study aimed to screen suitable excellent cherry varieties for cultivation in Northern Guizhou region. [Method] In 2011-2014, various biological traits of two new introduced cherry varieties and a local variety were evaluated and compared, including plant growth, characteristics of branches, leaves and flowers, fruit economic traits, phenological response, yield traits and stress resistance. [Result] Black Pearl and Pitch-Black-skinned Cherry exhibited better performance than the local variety, with the branch germination rate of 85.42% and 80.95%, branching rate of 18.75% and 15.87%, spring shoot length of 35.5 cm and 31.6 cm, annual spring shoot growth of 6 223.2 and 5 956.6 cm, leaf size of 14.9 cm × 7.6 cm and 13.8 cm × 8.1 cm, flower size of 2.5 cm ×2.6 cm and 2.3 cm × 2.4 cm, fruit ma- turity stage in late April-early May and early-mid May, average single fruit weight of 3.85 g and 3.68 g, sugar content in fruit juice of 14.5% and 14.2%, fruit edible rate of 76.47% and 77.23%, fruit-bearing rate of 28.48% and 29.81%, average yield per plant of 15.6 kg and 11.9 kg, converted output of 12 282 kg/hm2 and 9 814.5 kg/hm2, respectively. In addition, these two new introduced cherry varieties demonstrated strong adaptability and relatively strong adaptability, respectively. Therefore, Black Pearl exhibited the best performance, followed by Pitch-Black-skinned Cherry, which were both superior to the local variety. [Conclusion] Black Pearl can be selected as the main cultivar with supporting cultivation techniques in Northern Guizhou region, appropriately combined with Pitch-Black-skinned Cherry. 展开更多

[Objective] This study aimed to select suitable cultivars of cut roses with prominent comprehensive performance which is suitable for the commercial promotion in the tropical region of South Hainan Province,including Sanya and the low-altitude area.[Method] Introduction experiment and production test were designed to observe the agronomic and economic traits of cultivars in a rose resources nursery established in Sanya.[Result] Through observation in the resources garden,18 varieties were chosen to conduct the introduction experiment,of which 8 varieties were selected to accomplish the production test.The results of the production test showed that 'Vendela','Golden Emblem','Samantha' and 'Tineke' showed the best adaptability;the cut flower quality of 'Carola','Black Magic' and 'Golden Emblem' belonged to the first grade;the yield of 'Movie Star','Golden Emblem' and 'Black Magic' was more than one million per hm2;except 'Golden Emblem',the vase life of the other seven cultivars was more than 10 days;'Carola','My Choice' and 'Perfume White' had better disease-and insect-resistance;'Carola','Vendela','Rouge Meilland','Tineke','Golden Emblem','Samantha','Perfume White','Saiun','Asagumo' and 'Double Delight' were more resistant to blackspot,while 'Black Magic','Versilla','Alec's Red' and 'Movie Star' were less resistant to blackspot.[Conclusion] Cultivars of cut roses were able to grow and develop normally in the tropical coastal area of Hainan Province,including South Hainan and Sanya,where it was appropriate for the production of cut roses.However,it is necessary to pay attention to the prevention and control of thrips and blackspot.'Black Magic','Carola','Vendela','Rouge Meilland','Golden Emblem','Tineke','Movie Star' and 'Samantha' showed best comprehensive performance,which were thus worthy of large-scale popularization in Hainan Province. 展开更多
