一、 雄性不育性的概念 What is plant male sterility? ● Sterility:There are no functional gamete in plant,or do not produce active zygote at some definite condition. O Plant male sterility:No normal anther, or pollen,or male gamete. ● 43 famila,162 genera,320 species ● Pattern of plant male sterility

Pattern of plant male sterility ○雌雄异株植物群体中，完全缺乏雄性个体或具 高度缺陷的雄性个体。 No male or the with abnormal male plants in the group of dioecism(雌雄异株 植物)
3 ● Pattern of plant male sterility ○雌雄异株植物群体中，完全缺乏雄性个体或具 高度缺陷的雄性个体。 No male or the with abnormal male plants in the group of dioecism(雌雄异株 植物)
O雌雄同株植物(monoecism)中： ◎雄性器官萎缩、畸形或消失 Stamen or anther compressed,scattered, or completely sloughed off during the development of stamen ©不能形成正常的小孢子发生组织 No normal microsporangium develope
4 ○雌雄同株植物(monoecism)中： ◎雄性器官萎缩、畸形或消失 Stamen or anther compressed, scattered, or completely sloughed off during the development of stamen ◎不能形成正常的小孢子发生组织 No normal microsporangium develope
回小孢子发生异常，形成不能存活、畸形或败育 花粉 Abnormal microspore developed, or microspores died, or sterile pollen developed ⊙花粉不能成熟或无萌发能力 No mature pollen .Pollen can not germinate ▣花粉有生活力但花药不开裂 No dehiscence of anthers found but with normal pollen 5
5 ◎小孢子发生异常，形成不能存活、畸形或败育 花粉 Abnormal microspore developed, or microspores died, or sterile pollen developed ◎花粉不能成熟或无萌发能力 No mature pollen. Pollen can not germinate ◎花粉有生活力但花药不开裂 No dehiscence of anthers found but with normal pollen
