Abstract: | [ Objective ] The research aimed to study the resistance to powdery mildew of the tried and pre-examination wheat cultivars in Anhui Province. [ Method] All the wheat cultivars in the experiment were artificial inoculated and then the disease severities were assessed. [ Result] The high-infection cultivars were 30%, the mid-infection cultivars were 53% and the mid-resistant cultivars were 17% in 2010. In 2011, the high-infection cultivars were 42% , the mid-infection cultivars were 47% and the mid-resistant cultivars were 11%. In 2012, the high-infection cultivars were 11% , the mid-infection cultivars were 57% and the mid-resistant cultivars were 32%. [ Conclusion] It can guide the breeding di- rection, and provide scientific basis for variety certification. |
