辣椒(甜椒)雄性不育系13733A、1592A、1442A的特征与形态解剖

1995年在辣椒田中发现雄性不育株，用不同果型的品种，分别进行测交，连续回交和父本株自交，育成了灯笼型、羊角型、牛角型等不同类型的3个雄性不育系和相应的保持系。不育系的长势、株幅、分枝明显强于可育株。各不育系的雌蕊功能正常，花药瘦小、干瘪，个别花药虽与保持系相似，但无粉粒或极少。个别不育系的个别植株有单性结实特性。

STUDIES ON THE CHARACTERS AND SHAPE DISSECTION OF MALE STERILE LINES OF PEPER(CAPSICUM ANNUUM L.)

Three male sterile lines and their maintainable lines of cattle-horn pepper, sheep-horn pepper, bell pepper were developed and recurrent; lines selected by means of test cross, successive backcross, and paternal plant self-cross of the male sterile pepper (Capsicum annum L.) were discovered in pepper plant in 1995. It is obvious that the male sterile lines are stronger than the male fertile plant on growth vigor and plant width branching number. It is normal on stigma of male sterile lines. The flower parts of the male sterile lines are significantly smaller than those of the maintainable lines. The anthers of the sterile lines are small, dry and shriveled in comparison with the maintainable lines and have few pollen grains or no grain at all, the male sterile lines have the character of partbenocarpy in some plant.
