摘要
通过分期播种、异地播种、控光控温试验，研究了甘蓝型油菜501-8S育性的变化规律；利用501-8S与甘蓝型油菜品种（系）正反交，F1自交、回交等，研究了其育性遗传规律。结果表明：501-8S是温度敏感型雄性不育系，属高温不育类型，日均温在12．5～17．5℃育性发生转换，光照长度对其育性无明显影响；501-8S属细胞质雄性不育类型，其育性受一对基因控制。
Fertility transformation was studied by seeding by stages,seeding in different regions and controlling photoperiod and temperature in phytotron. The character of fertility transformation of 501-8S was thermo-sensitive, showed male sterility in high-temperature. The temperature of fertility transformation was between 12.5℃ and 17.5℃; The photoperiod had no obvious effect on the fertility transformation. Genetic studies indicated that 501-8S was CMS line, a pair of gene controlled the fertility, and restore gene was dominant.
