Abstract:: 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.
