| 摘 要： | 采用与育种同步的抗性鉴定方法，利用日本鉴别菌系作为鉴别标准品种，分析了Pi-z、Pi-ta2等基因2002-2007年在云南水稻稻瘟病抗性育种实践中的表现。结果表明，截至2007年，Pi-z、Pi-ta2 、Pi-zt在云南稻区仍然有利用价值； Pi-ta2叶/穗瘟抗性反应表现明显不一致；Pi-z、Pi-zt在各种育种材料中叶/穗瘟抗性表现一致；在不同抗性组合中，发现Pi-z对育种材料的抗性改良效果更明显。

| Abstract: | Japan strains was used as standard varieties and resistance identification method was synchronized with breeding,the performance of Pi-z,Pi-ta2 genes was analyzed in blast resistant rice breeding in Yunnan from 2002 to 2007.The result showed that till 2007 Pi-ta2,Pi-z and Pi-zt genes were still of utilization value in rice producing reigns of Yunan,and resistance of Pi-ta2 had distinct inconformity between leaf resistance and spike resistance to blast,while the other two had the same performance.Pi-z had mo... |
