黄瓜枯萎病是北京地区露地春黄瓜及保护地黄瓜的主要病害之一,该病害分布极广,全国各地均有发生,常年发病率为10—30％左右。如遇病害流行,发病率可达80—90％,造成大面积枯萎死亡,严重地影响黄瓜产量,是黄瓜生产上的主要威胁。选育抗病品种是防治枯萎病的有效途径,而抗病鉴定工作又是抗病育种的重要环节。为了给抗病育种提供可利用的抗病种质材料,对黄瓜枯萎病的抗病鉴定研究做了以 Cucumber Fusarium wilt is one of the major diseases of spring cucumber and cucumber in protected areas in Beijing. The disease is widely distributed throughout the country, and its annual incidence is about 10-30%. In case of epidemics, the incidence of up to 80-90%, resulting in a large area withered death, a serious impact on cucumber yield, is the main threat to cucumber production. Breeding resistant varieties is an effective way to prevent and control Fusarium Wilt, and the identification of disease resistance is an important part of disease-resistant breeding. In order to provide disease-resistant breeding available disease-resistant germplasm materials, the cucumber Fusarium wilt disease identification study done
