| 摘 要： | 为给克隆无蜡粉基因提供理论依据，减少无蜡粉基因分子标记的工作量，对用白菜型油菜有蜡粉材料Ｃ１－３３与甘蓝型油菜无蜡粉材料１０４７种间杂交获得的Ｆ１，自交所得Ｆ２，以及与Ｃ１－３３回交获得的ＢＣ１，ＢＣ２代的蜡粉性状分离进行了观察。结果表明，１０４７中显性无蜡粉基因位于甘蓝型油菜的Ａ染色体组上。 |

| Abstract: | Brassica rapa accession C1 33 was crossed with waxless inbred line 1047 of B.napus. The F 1 hybrids were selfed or backcrossed to C1 33 as male parent.The observation of segregation for waxlessness in F 2,BC 1 and BC 2 showed that the dominant gene for waxlessness in line 1047 was located at genome A of B.napus. The results will provide a foundation for molecular mapping and cloning of the gene. |
| Keywords: | Brassica napus Brassica rapa interspecific cross gene |
