目的]明确安徽省正试和预试品种对小麦白粉病的抗性水平。方法]采用田间人工接种鉴定的方法,连续3年对供试的小麦品种进行了抗性鉴定。结果]2010年参试品种对白粉病表现高感的品种占30%,中感品种占53%,中抗品种占17%;2011年高感品种占42%,中感品种占47%,中抗品种占11%;2012年表现为高感的品种占11%,中感品种占57%,中抗品种占32%。结论]为引导育种方向及品种审定提供了理论依据。

Resistance Identification of Wheat Cultivars on Powdery Mildew in Anhui Province

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.
