In order to resolve current problems of Chinese rapeseed industry, suggestions were put forward by combing present situation, prediction and practicable strategies of rapeseed industry. Challenges in Chinese rapeseed industry were analyzed, which included competition from international company; separation between breeding, popularization, and market demand; backward breeding model and R&D(research and development) in enterprise; lack of effective market regulation. Suggestions were made to improve rapeseed industry. First, comprehensive and rational modern rapeseed industry scientific development view should be applied in regional distribution of rapeseed production. Second, rapeseed breeding of China should coordinated and a platform should be formed for breeding innovation. Third, rapeseed multifunctional development and utilization need to be improved to meet the new consumption demand. At last, market supervision must be strengthened to ensure the sustainability and healthy development of seed industry. This paper provided theoretical references for rapeseed breeding and production applications, and established a solid foundation for rapeseed production and popularization in China.展开更多
