Abstract：[Objective]Mung bean is animportant dual-purposecropforboth medicinalandfooduses，widelycultivated worldwide.Withongoingoptimization ofagricultural production systems and evolving public health consciousnessand dietarypatterns，market demandfor mungbeanscontinues torise.AsoneofChina’smain productionregions，ShanxiProvince face significantagriculturalconstraintsduetolimitednaturalprecipitationandfrequentdroughtconditions.Theactiveidentificationof drought-tolerant mung bean germplasmresources holdsstrategic importanceforpromotingarid landutlzationandagricultural industry development.[Method]In this study，35 mung bean germplasmresources were evaluatedunder simulated drought stress using 10% polyethylene glycol 6Ooo（PEG6ooO）solution at seedling stage.Twelve morphological traits，including plant height，rootlength，fresh weight，dryweight，androotsurfacearea，andlOphysiologicalindicators，including malondialdehyde，solubleprotein，peroxidase，chlorophyll，andsuperoxideanionrdicals，weremeasured.Droughttolerancecoficients Werecalculated foreach strain，folowedbycorrelationanalysis.Comprehensiveevaluationof drought tolerance wereper formedusing integratedapproachesincluding membershipfunctionanalysis，pricipalcomponentanalysis，andhierarchicalclus teranalysis.[Result]Basedonestablished drought tolerance clasificationcriteria andcomprehensive evaluation，the 35 mung beanstrains werecategorized intofivedistictgroups：highlydrought-tolerant（onestrain：529），drought-tolerant（9 strains： 311，360，368，386，500，307，751，92and94O），moderatelydrought-tolerant（14 strains），drought-sensitive（7 strains）， andhighlydrought-sensitive（4 strains）.[Coclusion]Thisstudysuccessull identifiedone highlydrought-tolerantandnine drought-tolerant mung bean germplasm resources from the 35 evaluated.These drought-tolerant mung bean germplasm resourcesprovidedarobusttheoreticalbasis formung beancultivationpracticesand industrialproduction，whilesupportingsus tainabledevelopmentofmung bean industryinaridareasand promoting eficientutilizationofdrylandresourcesin ShanxiProvince.
