There were more than one thousand local soybean [Glycine max(L.) Merr.] germplasms in Hubei province.However,their diversity was not well characterized.The objective of this study was to quantify genetic diversity of sixty-four soybean landraces from Hubei by SSR and cluster analysis with the UPGMA method.166 polymorphic bands were amplified by twenty-seven pairs SSR primers.Genetic diversity index showed that distribution of Simpson index was 0.2406~0.9037 and mean 0.6960,and distribution of Shannon-weaver index was 0.4800~2.4684 and mean 1.4538.By using the dendrogram analysis,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 level of soybean landrace from Jianghan alluvial plain was higher than that of other landraces.
