【摘要】 【目的】鉴定新疆小麦审定品种(系)抗病性相关基因，为小麦育种遗传改良提供材料。【方法】利用KASP技术对183份新疆小麦品种(系)的抗病性相关基因进行检测。【结果】99份材料携带抗叶锈病基因Lr46,频率为54.10%,64份材料携带抗叶锈病基因Lr14a,频率为34.97%,3份材料携带抗叶锈病基因Lr68,0份材料携带抗白粉病基因Pm21。新疆小麦品种(系)中抗病基因的分布频率较低，约为26.8%。【结论】筛选出的146份材料可以作为新疆小麦持久抗锈病育种的抗源材料。更多还原

【Abstract】 【Objective】 This study aims to identify the genes related to disease resistance of Xinjiang wheat varieties(lines) and provide materials for genetic improvement of wheat breeding.【Methods】 In the present study, KASP technology was used to detect the genes related to disease resistance in 183 Xinjiang wheat varieties(lines).【Results】 The results showed that 99 varieties had the leaf rust resistance gene Lr46 with a frequency of 54.10%,64 varieties had the leaf rust resistance gene Lr14a with a frequency of 34.97%,3 varieties had the leaf rust resistance gene Lr68,no variety had the powdery mildew resistance gene Pm21 and yellow rust resistance gene Yr15.The distribution frequency of resistance genes in Xinjiang wheat varieties(lines) was low with a frequency of about 26.8%.【Conclusion】 The 146 selected materials could be used as resistance materials for wheat breeding of long term rust resistance in Xinjiang.更多还原
