摘要

[Objective]The paper was to determine the resistance level of the tried and pre-examination wheat cultivars against powdery mildew in Anhui Province of China.[Method]By using artificial inoculation and identification method in fields,the resistance of wheat cultivars was identified in consecutive three years from 2010 to 2012.[Result]The highly susceptible(HS)cultivar accounted for 30%,42%and 11%of total tested cultivars in the years of 2010,2011 and2012,respectively;moderately susceptible(MS)cultivar accounted for 53%of total tested cultivars in 2010,which accounted for 47%and 57%in 2011 and2012,respectively;moderately resistant(MR)cultivar accounted for 17%of total tested cultivars in 2010,which accounted for 11%and 32%in 2011 and 2012,respectively.[Conclusion]The paper can guide breeding direction,and also provide scientific basis for variety approval.
