Abstract
Wheat powdery mildew is a leaf disease that occurs during the whole growth period of wheat, which can significantly reduce the yield and quality of wheat. Planting disease-resistant varieties has always been regarded as the most economical, safe and effective way to control wheat diseases. In order to grasp the resistance level of main plant varieties, newly approved varieties and some high-generation lines to powdery mildew in the middle and lower reaches of the Yangtze River and the Huanghuai wheat area. In this study, the physiological race 52-27 of powdery mildew was used to identify the disease resistance at the seedling stage of the main varieties and reserve wheat vari-eties (lines) in the middle and lower reaches of the Yangtze River and the Huanghuai wheat region; the physiological races E21, 52-27 and 2-40 were used for disease resistance identification of 49 wheat varieties (lines). The results showed that among the 74 test varieties (lines) with resistance at the seedling stage, 25 were resistant to 52-27, accounting for 35.21%. Among the 49 cultivars (lines) identified by the in vitro leaf segment method, 13 were resistant to E21, accounting for 26.53%; 17 were resistant to 52-27, accounting for 34.69%; 12 were resistant to 2-40, accounting for 24.49%; 2 of the 3 races were resistant to disease, accounting for 4.08%.Keywords
