| Abstract: | By using the generations derived from restorer line C418 backcrossing with parent-Xa21 gene,through molecular marker assisted selection,inoculating representative strains,examining agronomic characters,testing combing ability,a series new restorer lines with Xa21 were bred.Comparatively with C418,these new restorer lines had higher resistance to bacterial blight,better agronomic characters,better combing ability,some new hybrid combinations with high quality were bred also,they would lay a matter foundation... |
