1999～2001年,在抗病性观察圃,利用常规的抗病性鉴定方法,对29份大田主栽冬小麦品种进行抗白粉性鉴定。结果表明,不同小麦品种系对白粉病抗、感性存在明显差异。高抗、中抗、中感及高感的品种系分别占参试材料的13.8%、58.6%、10.3%及17.2%。其中中88375、中85130、蓝天3号、清山895等4个品种系对小麦白粉病连续2a以上表现出稳定的抗性。
From 1999 to 2001, 29 field-grown winter wheat cultivars were identified for resistance to white powder in the disease resistance observation nursery using conventional disease resistance identification methods. The results showed that there were significant differences in resistance and susceptibility to powdery mildew among different wheat lines. The varieties with high resistance, medium resistance, medium sensitivity and high sensitivity accounted for 13.8%, 58.6%, 10.3% and 17.2% of the tested materials, respectively. Among them, 88.375, 85130, 3 blue sky, 895 Qing Qianshan and other 4 varieties of wheat powdery mildew for more than 2a consecutive showed stable resistance.
