Abstract:: T here were more than one thousand local soybean [ Glycine max (L.) Merr. ] germplasms inHubei province. However , their diversity was not well characterized. The objective of this study was toquantify genetic diversity of sixty-four soybean landraces from Hubei by SSR and cluster analysis with theUPGMA method. 166 polymorphic bands were amplified by twenty-seven pairs SSR primers. Genetic di-versity index showed that distribution of Simpson index was 0. 2406～ 0. 9037 and mean 0. 6960, and distri-bution of Shannon-weaver index was 0. 4800 ～ 2. 4684 and mean 1. 4538. By using the dendrogram analy-sis, 64 landraces were separated into three major groups at the DNA level :Jianghan alluvial plain group,northwest Hubei group and mixed group of the east , south and west of Hubei province. The diversity levelof soybean landrace from Jianghan alluvial plain was higher than that of other landraces.
