为了解甘肃天水近年育成品系中抗条锈病基因的分布情况，选用与Yr5和Yr10基因紧密连锁的标记，对38份冬小麦品系进行抗条锈病基因检测。结果表明，38份品系中，有15份品系检测到Yr5基因，有1份品系检测到Yr10基因，分别占被检测品系的39.5%和2.6%；品系0817-4同时检测到Yr5和Yr10基因，由于两基因对目前流行小种有较好的抗性，建议品系0817-4可在甘肃天水小麦抗条锈病育种中合理利用。

In order to know the distribution of Yr5 and Yr10 genes in wheat lines in Tianshui of Gansu， using molecular markers tightly linked with Yr5 and Yr10， 38 wheat lines are detected the existence of stripe rust resistant genes Yr5 and Yr10. The result shows that there are 15 lines containing Yr5 gene， accounting for 39.5 of the total tested lines， 1 line with Yr10 gene accounting for 2.6% of the total tested lines. The line 0817-4 contained both Yr5 and Yr10 genes， which could be widely used in wheat breeding in Tianshui of Gansu.
