摘　　要：为了分析抗叶锈病基因在青海审定小麦品种中的分布状况,采用6个抗叶锈基因(Lr1、Lr9、Lr24、Lr29、Lr34、Lr42)的分子标记对青海省审定的66个小麦品种进行检测。检测结果显示:66份小麦品种中,16个品种含Lr1,占24.24%;18个品种含Lr24,占27.27%;31个品种含Lr29,占46.97%;5个品种含Lr34,占7.58%;23个品种含Lr42,占34.85%;未检测到Lr9。另外,同时含有2个抗叶锈基因的小麦品种17份,占25.76%,同时含有3个抗性基因的品种9份,占13.64%,同时含有4个或4个以上的品种仅1份,为‘青春254’。To analyze the distribution of leaf rust resistance genes in 66 bread wheat cultivars which were released in Qinghai Province,six molecular markers of leaf rust resistance genes(Lr1,Lr9,Lr24,Lr29,Lr34,Lr42)were applied to test 66 wheat cultivars.Of the 66 Qinghai released cultivars,16 cultivars carry Lr1 gene;0 cultivars carry Lr9 gene;18 cultivars carry Lr24 gene;31 cultivars carry Lr29 gene;5 cultivars carry Lr34 gene;and 23 cultivars carry Lr42 gene;accounting for 24.24%,0%,27.27%,46.97%,7.58%and 34.85%of the detected samples,respectively.Meanwhile,17 samples contain two resistance genes,accounting for 25.76%;9 samples contain three resistance genes,accounting for 13.64%;only‘Qingchun 254’contain four resistance genes.The distribution of Leaf Rust Resistance Genes in 66 wheat cultivars in Qinghai province provides the resources of resistance gene and has potential value for improving the resistance of leaf rust by pyramiding leaf rust resistant genes.
