There were more than one thousand soybean(Glycine max(L.) Merr)germplasms in Hubei province.In order to evaluate the genetic diversity of summer sowing soybean landraces from different agricultural divisions of Hubei,we analyzed allelic profiles at 28 simple-sequence repeat(SSR) loci of 92 accessions.The SSR loci produced 134 alleles,and each SSR loci could detect 2 to 9 alleles with an average of 4.78 alleles per loci.The highest averages of both genetic diversity index and alleles were all occurred in southwest division,and second one was Jianghan Plain division.More than 83.6% of total variation was produced by geographical differentiation.By using the cluster analysis with Within-groups Linkage method,92 landraces were classified into three major groups at DNA level.Many landraces from southwest division and Jianghan Plain were clustered in Ⅰand Ⅲ group respectively.It was suggested that the diversity level of soybean landrace from both southwest and Jianghan Plain division were higher than those from other divisions.
