| 摘 要： | 甘蓝型油菜双低不育系黔油2AB经遗传鉴定表明，其育性稳定，不受栽培、气候等环境因素干扰；恢保关系有别于其它不育源，育性受两对细胞核显性基因（杂合型两型系）控制，属细胞核显性不育系，是开展优质杂交油菜品种选育的重要亲本材料。

| Abstract: | The sterile identification and genetics analysis of n ew sterileline Qianyou 2AB with good quality in B.napus showed that Qianyo u 2ABs maintaining and restoring abilities were different from that of other male sterile lines.The sterility of Qianyou 2A was stable,and was controlled by two pairs of dominant nuclei sterile genes,indicating that Qianyou 2AB was domi nant nuelei male sterile line (heterozygous)and was a good parent material for b reeding of hybrid rape with good quality. |
