| 摘 要： | 对来自中油８２１的油菜核不育材料８２１Ａ进行遗传研究，表明其不良性受两对隐性重叠基因所控制，测交组合Ｆ１全恢复可育，Ｆ２代可育与不育株出现１５；１分离，回交一代出现３：１分离，连续兄妹交呈１：１分离，８２１Ａ性状优良，所配组合杂种优势强。这一优良种质正用于转育新的“双低”优质核不育系。

| Abstract: | The genetic research of GMS line 821A, which comes from Zhongyou 821, has been done. The results show that the sterility has been controlled by two pairs of recessive genes. In test-cross, F1 plants are all fertile, and fertile plants to sterile plants is 15:1 in F2, 3:1 in BC1,1:1 in sib-mating. The agronomic characters of 821A are good, and can be used to make up superior F1 hy-brid. 821A is being used to breed 'Double Zero' new GMS lines. |
