摘　　要：JN55A是通过芥菜型油菜×甘蓝型油菜创建的雄性不育材料。用Polima CMS的14份恢复系和保持系对其进行测交和恢、保关系研究的结果表明,该不育材料属核-质互作类型,具有与Polima CMS相同的恢、保关系,并具有广泛的恢复源和保持源。据此可知,JN55A属Polima CMS类型。B. napus L. JN55A, created by crossing between Brassica juncea L. and Brassica napus L. ,was crossed by 14 maintainers and restorers of PollmaCMS to research the restorer-maintainer relationship between Pollma and JN55A in this paper. The results showed that the sterility of JN55A was controlled by the sterile genes coming from cytoplasm and nuclear, and the restorer- maintainer relationship between Polima and JN55A was same, as well as the restoring and maintaining genes of JN55A were found widely, so JN55A was considered as a type of cytoplasmic male sterility as PolimaCMS.
