The genetic diversity of 60 soybean germplasm resources in Hebei were analyzed by POD isozyme and RAPD molecular markers. The result showed that there were 12 bands of POD isozyme and 21 kinds of zymogram styles. The materials from ecological regions could be plotted out by this method. Total 58 RAPD bands obtained from 10 primers. Among them 29 were ploymorphic bands. The tested materials could be divided into 8 groups. RAPD marker indicated better results than POD isozyme for revealing genetic background and consanguinity. The cluster analysis of varieties and lines exhibited their relation to the geographic origin.
