Soybean is one of the world's most important crops,which provids a large amount of protein and fat for the people.For such an important crop,it's breeding still depends upon a relatively narrow base of genetic resources(Delannay et al.,1983,Lohnes & Bernard,1991,Zhang,1987),so itrestricts the improvement of soybean yield.quality and resistance.Wild soybeans are of great interest as a potential genetic resource(Hadley & Hymowitz,1973),therefore,studing and using them to create new germplasms have been becoming an important program in soybean breeding.
