Abstract：Toclarifythewet-coldtoleranceofcucumber，diferentcultivars fromthreeeco-types wereidentified bythe wet-coldhurtindexandwet-coldtolerancevaluepredictionequationmethod，respectively.Theresultsshowedthatinthe 61cultivars，the maximum wet-cold hurtindexwas0.950andthe minimum wet-cold tolerance value was 0.127，bothrefer to cultivarJD102; the minimum wet-cold hurt index was0.103andthe maximum wet-cold tolerance value was1.408， both refer tocultivarMN3.The greater the wet-coldhurt index，the smaller the wet-cold tolerance value，andthepoorer the wet-coldtoleranceof thecultivar willbe.Thequantitativeresults identifiedbythetwo methods werehighlyconsistent，reflecting the wet-cold toleranceof thecultivarsfrom different perspectives.Basedonthequantitativeidentification resultsofboth wet-coldhurt indexandwet-cold tolerance value，all61cultivarscanbequalitativelyclasified into four categories： Wet-cold sensitivetype，wet-cold weak toleranttype，wet-cold medium toleranttypeand wet-cold strong tolerant type.There were8，32，14and7cultivarsofthecorespondingtypesforwet-coldurtindexclasification，and9，36， 10and 6cultivars for wet-cold tolerance value classification，respectively.The twoqualitative classification wasbasically consistent.Thewet-cold toleranceofcucumbercultivars wasrelated totheireco-types.Inboth theEuropean greenhouse typeand the North China type，there werecultivars with varyingdegrees of wet-cold tolerance.However，inthe former， the proportion of medium tolerant andstrong tolerant cultivars wererelatively high.Inthe South China type，all were wet-cold sensitiveor weak tolerant.Theresearch resultscan provideabasis forthecultivar selection incucumber cultivation and the wet-cold tolerant breeding.
