Abstract:
　The genetic relationships among 8 populations of Glycinne soja and 20 varieties of G. max fromnortheast of China were analyzed by RAPD method. 141 bands were amplified totally with 9 primers, inwhich 6 bands were homologous , 21 bands were unique and 114 bands were polymorphic respectively. Theresults showed that there were high polymorphic between G. soja andG. max in Northeast of China. Phy-logenetic tree of cultivars was obtained through UPGMA cluster analysis. All cultivars were clustered at0. 45 to 0. 80 distance level , 5 clusters were branched at 0. 57. Wild species(G. soja 01- 336)and cultivar(G. max Heinong 40)were clustered solely from other cultivars, and the rest were crossed and divided to8 clusters again. In the same cluster , the relationships of the wild species were closed and insulated signifi-cantly with cultivars. In the different clusters, the relationships of the wild species were far and the segre-gation was stronger than G. soja and G. max that of the same cluster.
