%X Random amplified polymorphic DNA (RAPD) analysis was applied to eight populations of wild soybeans (Glycine soja ) from five different latitudes and five populations within Jinhua, Zhejiang Province respectively. Cluster analysis based on genetic distance generated from the RAPD data showed that there were high genetic variations among G. soja populations from different latitude and within Jinhua area. There were some evidences showing noticeable correlation existed between the variations and the geographical latitude. Shannon phenotypic diversity index indicated that 78.5% of the molecular variation existed among populations. The study implied that the variation of wild soybean were correlative to the environment gradient in a large range, but were determined by random genetic drift in a small area.
