Soybean (Glycine max L.) is crucial legumecrop as source of high quality vegetable protein and oil, andKorea is regarded as a part of center of soybean origin. Toexpand the information of conserved genetic diversity, weanalyzed the genetic variability of soybean collection mainlyintroduced Korean accessions using 75 microsatellite markers. A total of 1,503 alleles with an average value of 20.0 alleleswere detected among 644 accessions. Korean collection revealedaverage allele number of 13.4 while Chinese, Japanese andSoutheast Asian accessions showed 9.0, 5.4 and 6.5 meanalleles, respectively. Especially, Korean accessions showedmore number of private allele per locus as 3.4 contrary toother geographical groups. The mean expected heterozygosityand polymorphic information content was 0.654 and 0.616,respectively, and expected heterozygosity values were notsignificantly distinguished according to the geographical groups. The phylogenetic dendrogram and deduced population structurebased on DNA profiles of 75 SSR loci showed Korean accessionsformed distinct gene pool against Chinese accessions,and could be divided into five subpopulations. Korean soybeanaccessions have specific genetic diversity and might be servethe valuable alleles for bio-industry as a part of the centerof soybean origin
