Soybean is one of the most economically important leguminous seed crops that provide the majority of plant proteins, and more than a quarter of the world's food and animal feed. At present, the soybean breeding technology in China mainly relys on conventional breeding, and the levels of both fundamental study and production lag behind those of the United States. Supported by "Innovative System of Designer Breeding by Molecular Modules", one of the strategic priority research programs of Chinese Academy of Sciences, Chinese soybean scientists have dissected several important molecular modules controlling yield and seed quality, revealed the coupling mechanisms of diverse molecular modules, bred a series of designer soybean varieties for field tests or regional trials, which together to establish the first-generation molecular module-based designer breeding systems in soybean. In the future, we should continue to strengthen germplasm resources evaluation and exploitation system, promote autonomy public database building, improve the data sharing mechanism, vigorously develop breakthrough technologies for high and stable yield soybean and for soybean replacement feed crops, speed up the molecular design breeding and artificial intelligence breeding systems, cultivate breakthrough soybean varieties, develop green and efficient cultivation techniques. With these studies, it is expected to enhance the soybeans production capacity and relieve soybean demand gap in China.
