本文对诸葛菜和芸苔属属间杂交的花粉粒萌发和花粉管生长情况进行了研究。其中用诸葛菜作父本，分别和甘蓝型油菜（“文油６号”、“云油３１号”）、“羽衣甘蓝”和白菜型油菜（“凤仪油菜”）杂交时，受精前有一定的亲和性；而和白菜型油菜（“玉溪周永达油菜”）、芥菜型油菜（“泸州四棱”、“南充油菜”）、埃塞俄比亚芥杂交时，存在受精前障碍。同时还发现通过蕾期授粉是克服属间杂交不亲和性的有效方法之一。 In this paper, we studied the germination of pollen grains and the growth of pollen tubes between the hybrids of Brassica and Brassica. Among them, when the plants were crossed with Brassica oleracea (“Wenyu No.6” and “Yunyou No.31”), “Kale” and Brassica campestris (“Fengyi Rape”) respectively, A certain degree of affinity; and cabbage type rape (“Yuxi Zhou Yongda rape”), mustard type rape (“Luzhou four edges”, “rapeseed”), Ethiopian mustard hybridization, there are pre-fertilization obstacles. It was also found that pollination through budding was one of the effective ways to overcome the incompatibility of the hybrids.
