不同黄瓜品种(材料)抗白粉病性研究

Study on Cucumber Resistance to Powder Mildew

对市场上常见的44个品种和育种部门提供的10份材料进行了抗白粉病性研究。结果表明,供试的54份黄瓜品种(材料)在抗病性水平上可分为高抗、抗病、中抗、中感、感病和高感6大类群,其中40.74%的黄瓜品种(材料)属于高抗,病情指数均小于6.5,为生产上合理布局和育种提供抗源。

The resistance of 54 cucumber varieties （materials）, collected from market and Breeding Sector, were evaluated for powder mildew in the field in 2009. According to the disease severity （ disease index）, 54 materials and varieties were divided into six resistance types. The high resistant varieties （materials） were 40.74 % of all tested and the disease index was all below 6.5. The results could be used for further study on resistant breeding.
