小麦条锈病是西藏小麦生产的重要病害之一。明确西藏当前主要小麦品种的抗条锈病基因及抗锈特性,对抗源材料的合理布局和利用以及持久抗条锈病品种的选育具有重要的意义。目前,国际上已正式命名了60多个小麦抗条锈病基因,而且这些基因都有可供检测的分子标记,利用分子标记可以快速检测到对应的抗条锈病基因[1]。当前,只有Yr5、Yr10、Yr15、Yr18和Yr26等基因对西藏乃至全国的条锈菌流行小种有 Wheat stripe rust is one of the most important diseases of wheat production in Tibet. It is of great significance to clarify the genes and rust resistance traits of the major wheat cultivars in Tibet, the rational layout and utilization of source materials, and the breeding of persistent stripe rust resistance cultivars. At present, more than 60 wheat stripe rust resistance genes have been officially named in the world, and all of these genes have molecular markers available for detection. Molecular markers can be used to rapidly detect the stripe rust resistance genes [1]. At present, only the genes of Yr5, Yr10, Yr15, Yr18 and Yr26,
