Abstract：To enrich the melongermplasm resources in China，60 thick-skinned melon accessions were introduced from theMiddleEast-CentralAsiaregion.Ninetenphenotypic traits were investigated，andcomprehensiveevaluationwas conducted using analytical methods such as baisc statistics，corelation analysis，principal component analysis（PCA），and clusteranalysis.Theresults showed that thecoefficient of variation for the19 phenotypic traitsranged from 4.32% to （204号 54.98% ，with the largest coefficient of variation observed in fruit umbilicus 54.98% ，and the highest genetic diversity index foundinyield（2.25）.H9-5，H9-40，andH9-37exhibitedstronggrowthvigor;H9-25，H9-13，andH9-15hdlarger fruitumbilici; H9-17exhibited greatersinglefruit mass，H9-10andH9-13hadthickerpericarp，andH9-50had thicker mesocarp.Yieldand growthperiodare influenced bymultiple factors，andcorrelationanalysis indicated thatthese two traits hadthe mostcomplexrelationships with other traits.Principalcomponent analysis simplified the19 traits into eight principal components， with a cumulative contribution rate of 86.044% ，named as growth vigor factor，morphology factor， yield factor，quality factor，and maturity factor. Cluster analysis clasifiedthe 6O germplasmresources into five groups， withsignificantdiferencesobservedamong the groupsintermsofyield potential，growthvigor，andmaturity.The top five thick-skinnedmelonsbasedoncomprehensiveevaluation wereH9-17，H9-26，H9-15，H9-29andH9-30.These findings demonstrate that the introduced germplasmresources fromthe MiddleEast-Central Asia region possess rich genetic diversity，holding significant value forbroadening the genetic basis of melon breeding breeding in China.
