利用引进的雄性不育株 ,进行大量测交 ,连续回交和父本自交 ,育成了灯笼形、羊角形、牛角形、线椒等不同类型的雄性不育系和保持系 ,其中牛角形类型筛选出相应的恢复系。在测交过程中 ,发现不同品种对雄性不育的保持能力有明显差异。不育系花药退化 ,无花粉粒或较少 ,醋酸洋红反应不着色或着色极浅 ,该不育属核质互作型 Male sterile lines were introduced into male sterile lines and maintainer lines of different types, such as lanterns, croissants, horns, and peppers Type the appropriate recovery system. In the process of measuring cross, we found that there are obvious differences in the ability of different varieties to maintain male sterility. Sterile anthers degenerate, pollen grains or less, acetic acid magenta reaction does not color or very pale coloring, the sterility of nuclear-type interaction
