甘蓝型油菜隐性细胞核雄性不育与波里马细胞质雄性不育可能具有完全不同的不育基因系统;采用有性杂交和连续回交的方法,将甘蓝型油菜隐性细胞核不育基因导入到含有波里马不育细胞质的基因型中,并得到甘蓝型油莱隐性细胞核+波里马细胞质雄性不育系RGCMS—S45A和RGCMS—117A及其相应的保持系S45B和117B;采用测交方法,从隐性细胞核雄性不育系中筛选出甘蓝型油菜隐性细胞核+波里马细胞质雄性不育保持系9个;波里马细胞质雄性不育的恢复系均是隐性细胞核+波里马细胞质雄性不育的恢复系。
The recessive nuclear male sterile of Brassica napus may have completely different male sterile gene systems with Polymorphic male sterile, and the sexual male sterile of Brassica napus was introduced into Polyploid male sterile lines RGCMS-S45A and RGCMS-117A and their corresponding maintainer lines S45B and 117B were obtained in genotypes containing Polymorphic sterile cytoplasm. Methods Nine recessive nuclei of Brassica napus + Polymorphic cytoplasmic male sterile lines were selected from recessive nuclear male sterile lines. The restorer lines of Polymorphic Cytoplasmic Male Sterility were both recessive nuclei + Restorer line of cytoplasmic male sterility.
