小麦条锈病是我国重要的小麦病害和主要防治对象。由于小麦品种的抗源单一,其抗锈性遗传基础日渐狭窄,定向选择导致新的高致病性条锈菌生理小种不断出现,使得我国95%左右的小麦生产品种“丧失”抗锈性。因此,筛选、鉴定和发掘新的抗源和培育持久抗病品种是当务之急~([1-2])。小麦品种兰考5号是优良的条锈病抗源,对我国现有的条锈菌生理小种均表现免疫或高抗。本研究对兰考5 Wheat stripe rust is an important wheat disease and the main control object in our country. Due to the single resistance of wheat cultivars, the genetic basis of rust resistance is becoming narrower and directional selection leads to the emergence of new pathogenic races of P. striiformis, which makes about 95% of wheat cultivars in China “lose” Rusty. Therefore, screening, identifying and exploring new sources of resistance and cultivating durable resistant varieties are imperative ([1-2]). Wheat variety Lankao 5 is an excellent anti-stripe rust source, which is immune or highly resistant to the existing race of races in China. This study of Lankao 5
