According to the Seed Law of the People's Republic of China,since May 2017, China has changed the original approval management of rapeseed varieties to registration management. Up to July 2021, a total of 1212 rapeseed varieties have been registered in China. In order to reveal the rapeseed breeding level and to perfect the function of variety registration system, it was reviewed on current situation of rapeseed varieties registered in China with suggestions. Based on the data, nearly half of the registered varieties were newly bred, mainly self bred Brassica napus hybrid varieties (except one from abroad), registered in provinces of the main production areas. Cold resistance trait received more attention. Disease resistance was enhanced. Oil content was significantly improved, and the quality was significantly improved as well. Problems included that most varieties were not applied for variety right protection, few varieties had short growth period which was becoming important. Thus we suggested to improve the process of variety registration system, including to revise the registration rules and guidelines soon. Considering the breeding direction, we suggested to strengthen the breeding on 3 features: short growth period, mechanized planting, and multifunction (for vegetable, green fertilizer and forage, etc.) for promoting high-quality development of China's rapeseed industry.
