Abstract:: Taking 68 domestic and foreign cucumber germplasms as material，resistance ofFusarium 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 Fusarium wilt.The results showed that there were 4 high 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.
