title: [Genetic analysis on restorer genes of D2-type CMS lines of common wheat].
abstract: On the basis of genetic characters of D2-type CMS lines, restorer lines Yi4060, M8003, 6D/6R, GR1, 960789, Bao769-22-1 et al. were gained from crossing selection. The results of genetic analysis of F2, F1BC1 population and allelic analysis of restorer genes, successive selection of self fertility from F1 showed that fertility restoration of these restorer lines was controlled by two pair independent major-genes(dominant) and different-dosage minor genes. Authors proposed that the two pair independent major-genes should be designated as D2Rf1 D2Rf1, D2Rf2 D2Rf2. The model C2(major genes + minor genes) should be first selected in breeding restorer line.
