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. Genetic variance 80.44% existing within population, 8.29% among populations and 11.27% among groups.

结果 （1）从100多个引物中选择出11个多态性强和重复性好的引物，扩增得到129条带；（2）不同居群内多态位点比率为20.9%－55.0%；（3）用UPGMA法得到所有样本的聚类图，可分为6个主要分支组和3个组外个体，其中四川中江居群的5个样本聚为一组，并与其他样本遗传距离较大；（4）按产地分组，遗传差异的80.44%存在于居群内，8.29%来自于组内居群间，11.27%的遗传差异来自于组间。
