摘　　要：以含有白叶枯病抗性基因Xa23的恢复系R659为抗性供体,福建省农业科学院水稻研究所育成的大穗型恢复系福恢2328为受体,进行白叶枯病抗性基因的导入,以期培育抗白叶枯病恢复系新种质,采用分子标记辅助选择技术,育成了2份含有Xa23基因的纯合改良株系EMR402、EMR403,经人工接菌鉴定,结果表明均对白叶枯病表现为抗。To breed new bacterial blight resistance germplasm resources, bacterial blight resistance gene came from restorer line R659 was introduced into large panicle type restorer line Fuhui 2328 that developed by Rice Research Institute, Fujian Academy of Agricultural Sciences, two improved lines EMR402, EMR403 contains gene Xa23 were bred using molecular marker assisted selection, artificial inoculation results showed that the materials resistant to bacterial blight.
