摘　　要：运用抗叶锈病基因Lr26、Lr34、Lr38的特异性分子标记,对122份小麦品种(系)进行了检测,以明确各品种(系)的抗叶锈性。结果表明:122份供试材料中,含有Lr26的有33个,含有Lr34的有3个,含有Lr38的有37个;同时含有Lr26和Lr38的有30个,同时含有Lr26、Lr34和Lr38的有3个。本研究结果可为小麦的抗叶锈育种提供理论参考。The objective of this work was to identify the wheat cultivars containing the leaf rust resistance gene Lr 26,Lr 34 and Lr 38 by specific molecular markers.Out of 122 wheat cultivars（lines）,33 cultivars were identified to contain the Lr 26 gene,3cultivars were identified to contain the Lr 34 gene,37cultivars were identified to contain the Lr 38 gene,only 3cultivars were identified to contain the Lr 26 Lr 34 and Lr 38 genes.The results of this study can provide a theoretical reference for the breeding of leaf rust resistance wheat.
