Abstract
Wild soybeans, Glycine soja, are a source of genetic variation to improve soybeans. To improve the efficiency evaluation of conserved germplasm a core or mini-core collection approach that maximizes allelic diversity in a proportion of the whole collection has frequently been advocated. The genetic diversity of a wild soybean collection (1,305 accessions) plus Japanese cultivated soybeans (53 accessions) were analyzed at 20 SSR marker loci. Higher levels of allelic diversity were found in wild soybeans (28 alleles per locus) than Japanese cultivated soybean (five alleles per locus). The genetic distance between wild soybeans from different regions reflected their proximity. Accessions from Russia consisted of a diverse array of alleles resulting in accessions being spread further apart in a PCA plot than accessions from other regions. Accessions of wild soybean from Korea included many rare alleles and thus had a high representation in the core collection. The two core collections developed here, traditional and mini, consisted of 192 accessions with 97% of the allelic diversity (14% of the whole collection) and 53 accessions with 62.4% of the allelic diversity (5% of the whole collection), respectively.
