摘　　要：“矮败”小麦等的异交结实率和太谷核不育小麦一样，受多种因素影响，变动幅度较大，其中最关键的因素乃是矮秆的不育穗受到高秆不育株叶片的荫蔽。适当除去不育穗顶部遮挡的叶片，辅之以人工辅助授粉，可获得满意的效果。用鸡毛帚授粉，是授粉工具的最佳选择。The crossing fertility of Dwarfing--Sterile Wheat which changed as large as that of Taigu Male--Sterile Genie Wheat, was affected by manyfactors, The most important factor was dwarfing sterile spikes shielded by leves of the higher fertile plants nearby. with the help of artificial supplementary pollination,a satifactory result can be reached by cutting out those leaves shielding the sterile spikes properly. And chicken--feather duster is ideal tool of artificial supplementary pollination.
