| 摘 要： | 通过对国际挑战计划项目(GCP)提供的146份小麦种质资源的千粒质量、穗粒数、单株穗数、株高、籽粒饱满度及产量等性状的综合鉴定及评价,结果表明,供试品种在产量、穗粒数、单株穗数等方面有着丰富的遗传多样性;各性状之间存在不同的相关性;抽穗期和成熟期对穗粒数、产量和千粒质量均有不同程度的影响。从供试品种中筛选出大穗丰产品种8个,大粒丰产品种8个,矮秆丰产品种5个,综合农艺性状好、丰产性突出的优良品种25个。

| Abstract: | An identification and evaluation for 1 000 seed weight,grain number per ear,ear number per plant,plant height,plumpness of kernels and yield of 146 wheat germplasms from GCP projects were conducted.The results showed that: the tested varieties had a wealth of genetic diversity in yield,grain number per ears,ear number per plant and so on;there were different correlations in each trait;heading and maturity stages had effects to grain number per ear,yield and 1 000 seed weight.We had successfully selected 8 big ear fertility varieties,8 big grain fertility varieties,5 short stalk fertilities and 25 fine varieties of super traits and outstanding fertility. |
