【摘要】 目的寻找并确定桔梗雄性不育材料。方法田间发现花药异常桔梗,进行自然授粉、人工辅助授粉和套袋自交处理,分别单收考种。结果发现6株花药异常的桔梗,其中3株花药瘦瘪或不裂药,自交结实率0%,不育度100%,雌蕊正常,自然授粉和人工辅助授粉皆能正常坐果结籽,种子发育良好。结论桔梗雄性不育株的发现,为桔梗种质资源杂交优势的利用开辟了新的途径。
【Abstract】 Objective To find and determine male-sterile plant of Chinese Bellflower.Methods After finding Chinese Bellflower plants with aberrant anther,the natural pollination,artificial pollination and self-crossing experiments were conducted and harvested individually.Results The rate of self-fertility of 3 plants with aberrant anther was very low(average only 0.00 %).However,the rate of natural fruit-set and artificial pollination was normal.Conclusion A new way was opened up for utilizing hydridization crossbreeding of germplasm resources since discovery male-sterile of Chinese Bellflower.
