利用 1 2对 SSR引物对 67份半野生大豆种质进行了遗传多样性的检测分析。结果表明 ,1 2个位点共检测到 1 84个等位基因变异 ,平均每个位点等位基因数目为 1 5.41个。平均多态性信息量、平均遗传多样性指数、平均遗传距离分别为 0 .849、0 .70 6、0 .1 1 8。根据 SSR分析结果 ,按欧式距离将 67份半野生大豆种质聚类并划分为 5个组群 The genetic diversity of 67 semi-wild soybean germplasms was analyzed using 12 pairs of SSR primers. The results showed that a total of 1 84 alleles were detected at 12 loci, with an average number of alleles per locus of 1 5.41. The average amount of polymorphic information, average genetic diversity index, and average genetic distance were 0.849, 0.70 6, 0.1 18 respectively. According to the results of SSR analysis, 67 semi-wild soybean germplasms were clustered according to European distance and divided into 5 groups
