摘　　要：以68份国内外黄瓜种质为试材,通过调查黄瓜种质的生长势、性型、叶色、瓜皮色及枯萎病病情指数,研究分析了不同黄瓜种质对枯萎病的抗性及抗性基因分布频率。结果表明:68份黄瓜种质中,高抗种质4份、占5.9%,抗病种质占36.8%,中抗种质占19.1%,感病种质占27.9%,高感种质占10.3%;华北型黄瓜较华南型和欧洲温室型黄瓜有较多的抗病基因;生长势越强,越抗枯萎病;强雌黄瓜较雌雄同株黄瓜抗枯萎病,叶片深绿的黄瓜较叶片黄绿和绿的黄瓜感枯萎病;瓜皮白绿的黄瓜较浅绿黄瓜感病,浅绿黄瓜较绿皮黄瓜感病。Taking 68 domestic and foreign cucumber germplasms as material,resistance of Fusarium wilt and the distribution of resistance genes were researched and analysised,through investigating growth vigor,sexual type,leaf color,rind color and disease index of Fusariumwilt.The results showed that there were 4high resistance germplasms and they were 5.9%,resistance germplasms were 36.8%,moderate resistance germplasms were 19.1%,susceptible germplasms were 27.9%,and high susceptible germplasms were 10.3%.Cucumbers in North China were more resistant than these in South China and European greenhouse cucumbers.The more was growth vigor,the more was resistance to Fusarium wilt.Strong female cucumbers were more resistant than monoecious cucumbers.The cucumbers that leave was dark green were more susceptible than yellowish green leaves and green leaves cucumber.The cucumbers that rind was white green were more susceptible than shallow green cucumbers,The cucumbers that rind was shallow green were more susceptible than green cucumber.
