摘　　要：研究了不同授粉处理方法、不同授粉时间、不同分枝授粉、不同来源花粉4种授粉条件对芸薹属作物种间杂交亲和性的影响。结果表明:蕾期授粉,一级分枝授粉,上午9:00～11:00授粉及采用复合花粉套袋授粉均可以有效地提高芸薹属白菜与根芥、叶芥及甘蓝型油菜的种间杂交亲和性。Dealed with four pollination conditions, including pollination stages, different grade branches, fertilization times, different pollens, which effecting the interspecific crosses between chinese cabbages （Brassica coznpestris） and root mustard （Brassica juncea ）, leaf mustard（Brassica juncea ）,and oil seed rape（Brassica napus） on their compatibility index. Results indicated that pollination at bud stages and at 9：00- 11：00 AM, pollination at first grade branch, and with pollen mixtures of different varieties were the optimized pollination conditions which could achieve high cross compatibility index between Brassica crops .
