Abstract:
Two hundred accessions of wild soybean, collected from Guangxi province were used as materials in this study. Twenty-three pairs SSR primers were used to analyze the genetic diversity of these materials. The result showed that one hundred and thirty-seven bands were amplified in twenty-three pairs SSR primers, with each locus has 5.96 bands. Genetic diversity index showed that distribution of Simpson index was 0.503-0.834, distribution of Shannon-weaver index was 0.407-1.444, and the dicesimilarity was 0.266-0.969， which suggestted that wild soybean collected from Guangxi had abundant genetic diversity. Clustering analysis showed that, two hundred accessions of wild soybean were divided into 3 categories. The genetic distance was very close among the materials in one population and also the materials of different populations because of their similar habitat. However, there were genetics differentiations in a same population.
