Abstract: There is a significant gap in soybean yield between China and the United States, and increasing yield is one of the key factors to break the difficulties in soybean production in China. This article summarized, compared, and analyzed typical high-yield soybeans in China and the United States. It was found that the reasons for the higher yield of American soybeans compared to Chinese soybeans were that soybean varieties had characteristics such as glyphosate resistance, high density tolerance, good disease resistance, and wide adaptability, excellent natural geographical conditions, good irrigation technology and management, and field management. By analyzing the reasons that affect the yield of soybean in China and the United States, it was proposed that the future direction of soybean breeding in China should focued on density tolerance and glyphosate resistance. Special attention should be paid to soybean cultivation techniques, such as reasonable planting and fertilization techniques, scientific irrigation and drainage, comprehensive pest and disease control, chemical regulation, agricultural mechanization and intelligence. Future research on soybean high-yield should also focus on the application of gene editing technology, innovation and application of precision agriculture and smart agriculture, strengthen international cooperation and exchange, and provide theoretical guidance for China’s soybean high-yield research and yield improvement.
