摘　　要：条锈病是小麦生产的重要病害之一,选育抗病品种是防治该病最为经济、安全和有效的途径。由于小麦条锈菌具有高度变异性且抗源的单一化,抗病品种抗性很容易丧失。因此,不断发掘新的抗条锈病基因资源,扩大抗源选择利用范围,对中国小麦抗病育种工作极为重要。对已命名的57个条锈病基因进行了总结分析,着重介绍了源于小麦一级、二级和三级基因源的各个抗条锈病基因的来源及其在染色体上的分布,并对条锈病抗源利用方面进行了分析及展望。Stripe rust is one of the most devastating diseases in common wheat.The appliance of resistantcultivars is the most economical,safety and efficient means to control the disease.Resistance cultivars easilylose resistance because that the wheat Puccinia striiformis f.sp.Tritici has high genetic variability.It issignificant to explore the new resistant resource and expand wheat genetic basis in resistance breeding work.The sources and distributions of 57 stripe rust genes are concluded in the paper.The genes from primary,secondary and tertiary Gen Bank are reviewed and suggested.Furthermore,the authors analyzed the utilizationof stripe rust resistance source.
