用油菜与菜进行了远缘杂交。以甘蓝型油菜为母本时 ,直接去雄授粉的有两个花序结实 ,共收获种子 3 9粒 ,其F1 有较大的分离。以菜为母本时 ,仅子房膨大 ,角果生长中途停止 ,但一直未枯死。试验结果表明油菜与菜的远缘杂交有一定的亲和性。 Distant crosses were made with rapeseed and Brassica chinensis. In the case of Brassica napus, the two male inflorescences were directly pollinated, and 39 seeds were harvested. To subtend vegetables as the female parent, only the ovary enlargement, halved growth halved, but has not died. The results showed that there was some affinity between the distant hybridization of Brassica campestris and Brasenia schreberi.
