在分析了我国油菜遗传育种形势后，认为：①抗病育种未开展系统研究，用中草药与油菜进行远缘杂交可能是抗病育种的重要途径；②油菜属间远缘杂交研究甚少，应该借鉴小麦属间杂交育种，拓宽我国甘蓝型油菜的遗传基础；③作者通过用菘蓝（板蓝根）、荠菜与甘蓝型油菜属间杂交成功的事例，认为孟德尔创建的种内杂交等位基因遗传学，难于指导和解释远缘杂交工作，应该创建新理论。
After analyzing the situation of rapeseed breeding in China, it is considered that: ①Systemic research on disease-resistant breeding is not carried out, and distant hybridization with Chinese herbal medicine and rapeseed may be an important way to resist disease breeding; ②Research on distant races hybridization of rapeseed is rare, Drawing on the interspecific crossbreeding between wheat and broadening the genetic basis of B. napus in China; (3) By means of the successful case of interspecific hybridization between Radix Isatidis (Radix Isatidis), Shepherd’s Purse and Brassica napus, the author thinks that the inheritance of intraspecific hybrid alleles Learn, difficult to guide and explain distant hybridization work, should create a new theory.
