摘要
采用苗期人工鉴定的方法,对烟台市农业科学院蔬菜研究所提供的101份烟台地方黄瓜高代自交系材料进行了白粉病及霜霉病的抗病性鉴定筛选,以期筛选出既抗白粉病又抗霜霉病的多抗黄瓜新品种。结果表明:有37份对白粉病的抗性表现为抗病,其中25份材料表现为免疫,抗病材料以华北型黄瓜居多,欧美型黄瓜次之,华南型黄瓜最少;有11份材料对霜霉病的抗性表现为抗病,无免疫及高抗材料;有7份材料对2种病害均表现为抗病。
By the method of seedling artificial identification,101 cucumber generations self-lines were identified to powdery mildew and downy mildew,which were provided by vegetable institute in Yantai Academy of Agricultural Science,to screen out multi resistance new cucumber both to powdery mildew and downy mildew.The results showed that,37 germplasms were resistant to powdery mildew.Among them 25 germplasms were immune.The majority was North China cucumber;the second was European and American cucumber;the minimum was South China type.Eleven germplasms were resistant to downy mildew;none was immune and high resistance.Seven germplasms were resistant to downy mildew and powdery mildew simultaneously.
