Wild soybean (Glycine, soja Sieb. and Zucc) is an important source of genetic variation to introduce useful traits into cultivated soybeans [Glycine max (L.) Merr.]. Wild soybean is widely distributed in Eastern Asia including, Korea, China, Japan, and other countries. Soybean breeders and geneticists are interested discovering useful genes from G. soja to introduce into cultivated soybean for variety improvement. Previous reports have shown that G. soja is a good source to find new and useful genes for resistance to biotic and abiotic stresses, improved seed composition, and agronomic characteristics such as yield for soybean variety improvement. Wild soybean populations at present are in decline and have a higher risk of extinction because human activities are infringing on and destroying the natural habitats of G. soja. Therefore, to preserve the genetic diversity and useful traits found in G. soja, it is necessary to collect and conserve accessions from unexplored regions native to wild soybeans as a valuable resource for soybean variety improvement.
