Abstract: In recent years,Chinese govemnmnt had bean made strategic adjustments to the planting structure in the Sickle Bay- area, in order to reduce corn planting area and increase soybean planting area, especially developing the early maturity soybean production in the north-eastern high-cold area. Scholars had bean done a lot of researches on the agronomic traits, ripening period, and variety- breeding of early-season soybeans. The previous studies on the early maturity soybean in significance of the development, ecological characteristics, breeding objectives and variety- breeding in China were summarized and the breeding methods and direction were investigated in order to provide reterence tor breeding and cultivation of early-maturing soybeans.
