摘　　要：雄性不育烟草MS云烟85的雄性败育发生在雄蕊原基分化后至孢原细胞形成前,在开放花朵中常能见到败育的雄蕊,其特征是花丝缩短,花药畸形、内无花粉或花粉空瘪。与正常烟草(保持系)子房由2心皮组成不同,雄性不育烟草MS云烟85子房都由3心皮组成。The stamen abortion of male-sterile tobacco Yun-yan 85 happened from the differentiation of stamen primordial to the formation of sporogenous cell. The staminodes were visible in opening flowers,but the filaments of staminode were shortened and the anthers were abnormal without pollen or with empty pollen. The ovary of pistil in male-sterile tobacco Yunyan 85 had 3 carpels, but the counterpart of normal tobacco（maintai- ner line） had only 2 carpels.
