摘　　要：研究了辐照花粉辅助授粉、杂交液辅助授粉及切割花柱授粉等措施对克服百合‘cordelia’(♀)×毛百合远缘杂交障碍的影响。结果表明:采用普通柱头授粉能够获得许多膨大果实和饱满种子,表明该杂交组合为亲合性组合。用经1000Gy或2500Gy剂量60Co辐照的母本花粉进行辅助授粉明显地提高了座果率和饱满种子结籽数,表明两种剂量的辐照花粉辅助授粉均能有效地克服该组合的杂交障碍。结籽数的提高有利于后续的选育工作。采用杂交液辅助授粉,座果率和饱满种子结籽数有所提高。而切割花柱授粉明显地减少了座果率和结籽数,表明该方法不适合于克服‘cordelia’(♀)×毛百合杂交障碍。The application of irradiated pollen assisting pollination, cross chemical assisting pollination and cut-style pollination in overcoming the cross barriers of lily ＇ cordelia＇ （ ♀ ） × Lilium dauricum were investigated. A number of fruits and plump seeds were produced by using the normal stigma pollination, which indicated that the cross was a compatible cross. The fact that the application of 1000Gy or 2000Gy irradiated pollen assisting pollination increased the fruitset and seedset obviously exhibited that this methods could overcome the cross barriers effectively. More hybrid seeds would have a positive effect on the future breeding selection. Application of cross chemical＇s assisting pollination raised the fruitset and seedset to some extent. The cut-style pollination method deduced the fruitset and seedset, which suggested that the method was not suitable for bypassing the cross barriers.
