- Abstract
The narrow genetic base of elite soybean, Glycine max (L.) Merr., germplasm may impede further attempts to improve grain yield and other important agronomic characters. Germplasm collections of wild soybean, Glycine sofa Siebold & Zucc., are a source of genetic variability for soybean breeding programs. The objectives of this research were to use genetic markers to characterize diversity among 60 G. sofa accessions collected in China and to compare this diversity with 18 U.S. ancestral soybean genotypes, 12 Chinese G. max plant introductions (Pls), and 47 elite soybean lines from the northern USA. These accessions were genotyped with a set of 72 simple sequence repeat markers. The G. sofa accessions were found to contain more alleles per locus (17) than the U.S. ancestral genotypes (5.8), the Chinese PIs (5.5), or the elite lines (4.5). Multivariate analyses were able to separate the G. max lines from the G. sofa accessions and identify the most diverse subset of G. sofa accessions. Multidimensional scaling separated G. sofa accessions from high and low latitudes, while Ward's clustering method separated the G. sofa accessions into distinct clusters that tended to include accessions from similar geographical regions. These data will be useful to breeders selecting G. sofa accessions as parents in a breeding program and for establishing a core collection of G. sofa to be used in future research.
