Results (1) From more than 100 primers, 11 primers producing polymorphism and reproduceable bands were selected, 129 bands were amplified.(2) The percentage of polymorphic bands within different populations were 20.9%-55.0%.(3) The cluster map including all samples were obtained by UPGMA. In the map, there were six cluster groups and three individuals outside the groups. The branch with five samples of Zhongjiang Sichuan population were far from other samples in genetic distance.(4) According to the distribution provinces five groups were divided in genetic variance analysis.
