摘　　要：为给培育小麦抗条锈病品种的种质选择及抗源的合理布局提供参考,选取108份对条锈病表现高抗或免疫的种质材料,用抗条锈病基因Yr10、Yr15、Yr18和Yr26的连锁分子标记进行检测。结果表明,9份材料可能含有Yr10,29份材料可能含有Yr15,25份材料可能含有Yr18,41份材料可能携带Yr26,分别占供试材料的8.3%、26.9%、23.1%和38.0%,其中有部分可能同时携带2种及以上抗条锈病基因。在供试材料中携带Yr26材料的比率较高,应加强与其他抗条锈基因的聚合,尽快将这些抗性基因应用到生产上。Linked molecular markers of stripe rust resistant genes Yr10,Yr15,Yr18,and Yr26 were used to detect 108 wheat resistant germplasms to provide basis for stripe resistant cultivar resources selection and reasonable distribution of their antigens.The results showed that 9 tested materials might contain Yr10,29 contain Yr15,25 contain Yr18,and 41 contain Yr26,which accounted for 8.3%,26.9%,23.1%,and 38.0%,respectively.Some tested materials might contain more than 2 stripe rust resistant genes.Tested materials which contained Yr26 took higher rate,it should strengthen their pyramiding with other resistance genes to apply these resistant genes in production.
