| 摘 要： | 使用40对SSR引物分析了8个省区天然野生大豆种群的遗传结构和遗传多样性.结果表明:15个种群共检测到633个等位基因,平均每对引物等位变异基因数平均值15.83个;种群平均Shannon指数(Ⅰ)0.7835,种群平均期望杂合度(He)0.4070,种群平均观察杂合度(Ho)0.0012,平均种群内遗传多样度(Hs)...

| Abstract: | Wild soybean(Glycine soja) is commonly accepted as the progenitor species of the cultivated soybean(Giycine max).They contain many characters potentially valuable for supplementing the soybean germplasm pool.Our objective was to evaluate the genetic diversities of wild soybean collected from 8 provinces in different latitudes of China.We sampled 15 representative natural populations in 2005.Forty public SSR primer pairs over the 20 linkage groups were applied to evaluate genetic diversity.A total of 633 ban... |
