| 摘 要： | 本文介绍了甘蓝型油菜CMS温度钝感不育系DA及其保持系DB的选育过程,分析比较了DA与23A、L17A和陕2A等不育系的花器形态、花期不同阶段和不同年份初花期不育系的育性稳定性。结果表明,DA属于典型的花药败育型雄性不育系,不育彻底、不育性稳定,在整个花期和不同年份都表现对环境温度变化不敏感。这可能与DA携带有对温度钝感的不育基因有关。

| Abstract: | The breeding process of CMS line DA with insensitivity to temperature and its maintenance line DB(Brassica napus L.) was described,and the differences of male sterile stability between DA and sterile lines 23A,L17A,Shan-2A were analyzed in flower morphology,flowering stages and eraly stage of flowering in different years.The results showed that the sterile line DA belonged to typical anther spoilable sterile type,its anthers spoiled completely and its sterile stablity was better.The sterile line DA was no s... |
