Wild Soybean(G.soja) Resources with High-protein and Introgression of Wild Germplasm into Cultivated Soybean in China

Wild soybean has been thought to be an important genetic resources because it has a high content of protein,high productivity of pods and/or seeds and high resistance to environmental stress.Many studies of the introgression of wild germplasm with high-protein into cultivated soybeans by crossing between wild and cultivated soybeans have demonstrated that the wild germplasm introgression is a very effective method to develop new soybean germplasms with high-protein.Further study hereditary laws in descendants of interspecific cross between wild and cultivated soybeans with high-protein will provide theoretical basis on expanding the genetic background in soybean breeding.
