中文摘要：
通过对5种（D型、K型、冈型、野败型、印尼水田谷型）不同类型质源的细胞质雄性不育系花粉的细胞学观察。结果显示，野败型和D型不育系花粉败育时间发生在单核期向双核期过渡阶段，这两种类型胞质不育系花粉败育过程基本类似；冈型不育系、K型不育系和印尼水田谷型不育系这3种细胞质雄性不育系的花粉败育时期略早于野败型和D型，一般在单核末期就全部败育，而这3种类型的胞质雄性不育系花粉败育过程基本相似。
英文摘要：
The test observed 5 different type of CMS lines （ D, K, Gang, WA, IN ）, and found that the abortion process of these five CMS lines were the same. There were a little difference only in some certain time. It also had a same abortion process between the type of WA and D, the time of abortion most happened at the stage from monoearyon to dikaryon. However, the Gang, K, IN, the 3 kinds of CMS lines had a familiar abortion process, the time of these 3 kinds was earlier than WA and D types. Generally, the 3 kinds of CMS lines all would abort in monocaryon late phase.
