Abstract

Genetic diversity of 56 high oil soybean cultivars from China were analyzed by using 47 pairs of SSR primer.The results showed that 289 alleles were produced by 47 pairs of SSR primer.The average allelic richness of polymorphic locus was 6.15.The index of genetic diversity ranged from 0.223 9 to 0.858 7 with an average of 0.667 9.The genetic similarity coefficients among all high oil varieties ranged from 0.117 to 0.926.It indicated that there actually existed sufficient genetic diversity among the high oil varieties.Cluster analysis results showed that 56 high oil soybean cultivars could be classified into 6 groups by using the UPGMA method according to the genetic similarity coefficient and the cluster pattern was correlated with the geographical distribution of the high oil soybean varieties to some degree.
