| 摘 要： | 利用47对SSR引物对我国80份高蛋白栽培大豆的遗传多样性进行了分析.结果表明,47对SSR引物在上述品种中共检测到309个等位变异.平均为6.57个:引物遗传多样性指数在0.279 6～0.8694之间,平均为0.639 0;品种间遗传相似系数变异在0.102～0.150之间,说明高蛋白大豆中存在丰富的遗传变异.利用品种间的遗传相似系数进行聚类分析.结果可将80份材料分为5个类群,其类群分布表现出一定的地域相关性.

| Abstract: | Genetic diversity of 80 high-protein soybeans varieties from China were analyzed by using 47 pairs of SSR primer.The results showed that 309 alleles were produced by 47 pairs of SSR primer.The average allelic richness of polymorphic loci was 6.57.The index of genetic diversity ranged from 0.2796 to 0.8694 with an average value of 0.6390.The genetic similarity coefficients among all high protein varieties ranged from 0.102 to 0.150.It indicated that there actually existed suf-ficient genetic diversity among ... |
