Abstract: In recent years, with the increase of domestic demand for soybeans, insufficient investment in science and technology long-term, the soybean yield increase slowly, the soybean has become increasingly prominent contradiction between supply and demand in China. The soybean varieties breeding,it has always been the goal of plant breeders of for a long time.The excellent varieties are the basis of high yield of soybeans. In the choice of soybean varieties, according to local conditions, try to use suitable for close planting, pests and diseases, lodging resistant varieties, at the same time to meet the local climate characteristics and farming conditions. In this paper, from 572 in the northeast soybean variety resources, select heilongjiang province second JiWenDai glaring 50 of ecological adaptability of materials. To learn more about 50 varieties bred varieties of genetic background, genetic structure and genetic relationship between, and the variety adaptability ability in all areas, to provide high quality germplasm resources use and development theory to guide, to provide information for the selection of breeding materials.
