甘蓝型油菜与芥菜型油菜杂交亲和性的研究结果表明，影响杂交亲和性的因素有杂交亲本、杂交组合方式和生态环境，芥菜型油菜作母本杂交亲和性高于甘蓝型油菜作母本的组合，昆明夏繁配组的甘芥杂交亲和性比长沙春季配组显著提高。芥甘杂种一代形态发育特性和种子油中主要脂肪酸含量多介于双亲之间，株高、分枝数、花期、棕榈酸和花生烯酸含量有超亲优势。芥甘杂种一代自交结荚结实差，作母本与甘蓝型油菜回交结荚率约２５％，与自由授粉相当，但平均每荚粒数比自由授粉增加约５０％；与芥菜型油菜回交和白菜型油菜杂交的结实性不如与甘蓝型油菜回交。
The results of crossbreeding affinity between Brassica napus and Brassica juncea showed that the factors influencing the crossbreeding compatibility were hybrid parents, cross combinations and ecological environment. The compatibility of Brassica juncea maternal hybrids was higher than that of Brassica napus Maternal combinations, Kunming Xiafan with the compatibility of sweet potato hybrids than the spring group in Changsha significantly increased. The morphological and developmental characteristics of the mustard hybrids and the major fatty acids in the seed oil were more than those between the parents. The plant height, branch number, florescence, palmitic acid The rate of backcrossing pod of mother mustard and rapeseed was about 25%, which was equivalent to free pollination, but the average number of pod grains was about 50% higher than that of free pollination. Rapeseed cabbage and rapeseed is not as strong as the backcross with the rapeseed.
