Two-dimensional representation of genetic relations among 40 Chinese soybean germplasm accessions from Gansu (G), Hebei (H), Sichuan (S) and Zhejiang (Z) and the cultivar CNS derived from a multi-dimensional scaling (MDS) analysis. Genetic distance estimates are based on Jaccard's genetic dissimilarity matrix of 241 RAPD fragments generated by 31 primers. The circles were drawn to indicate the consensus clusters presented in Table 1.
