摘　　要：利用单一接种法,分别接种鉴定了24个黄瓜种质材料对黄瓜白粉病、霜霉病、褐斑病和枯萎病的抗性。结果表明,有3份材料高抗白粉病,9份材料抗白粉病;2份材料高抗霜霉病,8份材料抗霜霉病;1份材料高抗褐斑病,12份材料达到抗病级;在枯萎病的接种试验中,没有发现高抗和抗病材料,仅得到了8份中抗材料。综合4种病原菌的接种结果,发现材料H、U、B、E、L、P对4种病害都达到中抗以上水平;材料V除了不抗枯萎病对其他3种叶部病害都达到高抗水平;材料H高抗霜霉病;材料R与材料J对白粉病达高抗水平。The resistance of 24 cucumber germplasms to powdery mildew,downy mildew,target leaf spot and fusarium wilt was identified by the method inoculating single pathogen every time.The results showed that 3 germplasms were highly resistant to and 10 were resistant to powdery mildew;2 germplasms were highly resistant to and 8 were resistant to downy mildew;one germplasm was highly resistant to and 12 were resistant to target leaf spot.For fusarium wilt,only 8 germplasms had moderate resistance to it.In our test,the germplasms H,U,B,E,L and P had more than moderate resistance to the four pathogens,and V was highly resistant to the other 3 pathogens except fusarium wilt;H was highly resistant to downy mildew;R and J were highly resistant to powdery mildew.
