Abstract：The present study was conducted to screen spring wheat cultivars(lines) which had resistance to wheat powdery mildew,and to define the distribution of Pm4,Pm8 and Pm21 in the spring wheat varieties (lines) in Xinjiang by seedling resistance identification and molecular markers detection of wheat resistance genes,so as to provide the basis for cultivar deployment and disease resistance breeding.The results showed that Xinchun No.38 and 366S showed resistance to wheat powdery mildew by wheat seedling resistance identification,and the ratio of high resistant plants to middle sensitive plants was 2∶ 1.Twenty nine wheat cultivars(lines) such as Xinchun No.12,Xinchun No.15,and Xinchun No.18 showed high sensitivity to wheat powdery mildew.Pm4 was detected in Xinchun No.27,1354 and 1360.Pm8 was detected in 983-S,MJ307,HMJ555 and 1112.Pm21 was detected in 366S.The combination of seedling resistance identification and molecular markers detection of wheat resistance genes can greatly improve the identification accuracy of wheat cultivars(lines) resistant to powdery mildew.
