Abstract：To clarifythe diferences among 22 new tomato varieties recommended bytheAgricultural Extension Center ofZhejiangprovincefortrialplanting，nineindicatorsweremeasured，combiningclusteranalysis，correlationanalysis， principal component analysis and stepwise regression analysis.The results showed significant diferences among the 22 varietiesacross various indicators，withvariation indexranging from 5.91% to 189.30% ，theproportionof deformed fruits exhibited the highest degreeof dispersion.Corelation analysis revealed that thesoluble solids content andthe numberof fruitsperclustershowedhighlysignificantpositivecorrelation，whileboth thenumberoffruitsperclusterandthesoluble solids content showed highly significant negativecorrelation with the single fruit massThreeprincipal components were extracted from nine indicators，the variance contribution rates are 42.444% ， 21.552% ，and 14.025% ，respectively. The loadingcoeficientmatrix was used to identifyindicatorscoveredbyeach principalcomponent，andacomprehensiveevaluation function was established torank the varieties basedoncomposite scores.Thesmall-fruited tomato variety Hangza 504 and the medium-to-large-fruited variety S21289-1ranked first.Stepwiseregressonanalysis identifiedseven indicators thatsignificantlyinfluenced tomatoqualityevaluation.Through clusteranalysis，thesmall-fruited tomatovarieties andthe medium-to-large-fruited tomato varieties werecategorized into three distinct groups basedonshared characteristicsrespectivily：Exhibition-type tomato，productivity-enhancing tomatoandculinary-purpose tomato.According tothe comprehensive evaluation，thesmal-fruited varieties Hangza 504，Hangza 515，and Ouxiu Huangying，themedium-to-large-fruited varieties S21289-1， ZheweiNo.2and Jiahong100 were demonstrated optimal performance.
