摘要
于2009年、2010年连续2 a采用自然苗圃法对郑州市推广种植的优质小麦品种进行了白粉病抗性鉴定。在供试的11个小麦品种中,无白粉病免疫及高抗品种,其中郑麦366在2009年、2010年的平均病情指数分别为42.27、15.18,均极显著低于对照品种郑麦9023,其相对抗病指数分别为0.56、0.70,属于中抗品种。周麦18、郑育麦9987为中感品种,周麦23、郑农16、豫麦34号、西农979、新麦18、郑农17、矮抗58、郑麦9023为高感品种。建议生产上推广应用郑麦366、周麦18和郑育麦9987小麦品种。
The resistance of 11 high-quality wheat cultivars promoted in Zhengzhou city to wheat powdery mildew was continually identified under natural condition from 2009 to 2010.Among 11 materials tested,no cultivar was immune or highly resistant to wheat powder mildew.The average disease index of Zhengmai 366 was 42.27 in 2009,and 15.18 in 2010,significantly lower than the contrastive cultivar（Zhengmai 9023）,while the relative resistant disease index was 0.56 and 0.70,respectively,thus Zhengmai 366 belonged to mid-resistant cultivars.Zhoumai 18 and Zhengyumai 9987 were mid-susceptive cultivars.Zhoumai 23,Zhengnong 16,Yumai 34,Xinong 979,Xinmai 18,Zhengnong 17,Aikang 58 and Zhengmai 9023 were highly susceptive cultivars.It was suggested that Zhengmai 366,Zhoumai 18 and Zhengyumai 9987 should be popularized and applied in production.
