| 摘 要： | 利用336个SSR标记和100个RAPD引物，对分子标记辅助选择获得的10个蜀恢527抗水稻白叶枯病改良系的遗传背景、白叶枯病的抗性和抗谱及农艺性状进行了研究。结果表明，10个改良株系在Xa21和Xa4位点纯合，抗我国7个病原型代表菌系CⅠ～CⅦ和菲律宾小种1和6（P1和P6）。在遗传背景分析检测的位点中，改良系与蜀恢527表现差异的SSR

| Abstract: | The genetic background, resistance spectrum to bacterial blight and agronomic traits were evaluated in 10 ‘Shuhui 527’ improved restoring lines with resistance to Bacterial blight, which were bred by Molecular Marker-assisted Selection(MAS). Results showed that these lines were homozygous in loci |
