| Abstract: | Objective] The germplasm resource of the wheat with the resistance to powdery mildew was screened through the experiment in the change of its disease-resisting.Method] The identification of the resistance of 136 different wheat varieties to powdery mildew in seedling stage was conducted.Results] There were,40 varieties with the high resistance,accounting to 29.4% of 136 tested varieties;58 varieties with the middle resistance(42.7%);24 susceptible varieties(17.6%);and 14 highly susceptible varieties(10.3%).The identification indicated that most of varieties were with highly-moderately resistance to powdery mildew and few susceptible varieties.In ecological type of those varieties,the semi-winter type of variety from Huaibei and spring type of wheat from Huainan were more resistance to the disease than the spring type of variety from Huaibei.Conclusion] The important basis of the rapid screening of resistant wheat variety was provided through the experiment in the identification of the variety's resistance to powdery mildew. |
