应用基因型选育的方法,获得核型显性不育基因的纯合基因型,创建了雄性不育的核显性不育系,经测试相应建立了核显性不育恢复系和保持系,首次完成核型显性不育的三系配套。
Genotypic breeding method was used to obtain the homozygous genotype of karyotype dominant sterility gene and the male sterility nuclear dominant CMS was established. Based on the test, the nucleus dominant sterile restorer lines and maintainer lines , For the first time to complete karyotype dominant sterile three-line package.
