An understanding of the relationship of geographically different soybean germplasm, based on selectively neutral DNA markers, could be useful in breeding programs on selection of divergent parentals. Although Japan, China, and Brazil are very important countries for consumption, production and as sources of genetic variation of soybean, the genetic relationship of soybean varieties, in these three regions, is not clear yet.The objective of this research was to assess the relationship of these three soybean germplasms, with a total of 272 varieties that are potential new sources of genetic
variation for soybean breeding programs.Two kinds of analyses, Hayashi ?s Quantification Theory III and UPGMA clustering, using 12 SSR markers, were performed to evaluate relationship among the three germplasms. In both analyses, Northeastern Chinese varieties and Japanese varieties were closely related but were classified separately.On the other hands,Brazilian varieties were distantly related and classi . ed into a completely different group to the other two germplasms.For clustering analysis, the genetic distances between varieties belonging to Japan, Northeast China,and Brazil ranged from 0.00-4.00,0.00-5.88, and 0.00-5.29, respectively. We observed that Chinese varieties
were the most divergent among the three regions,being that more than 95%of them ranged up to 4.14. In addition, Brazilian varieties ranged from 0.00-3.86, except for two varieties.The differences among regions were much larger than within each region (ex.the distance between Brazilian and other two was 8.69). These findings indicate that exchanges of these three germplasms must be useful for breeders since it would increase the genetic variability on the soybean breeding programs.
