Abstract：To provideareference for the introductionand breeding of highqualityvarietiesoffacilitylong cowpea n the coastal areasofGuangxi，thegreyrelational analysismethodwasusedtocomprehensively analyze17indicators includingthemainagronomictraits，qualitytraits，andstorage toleranceof31longcowpea varieties.Theresultsshowedthatthe coefficient of variation of agronomic traitsamong thevarietiesranged from 6.59% to 34.05% ，with the lowest for single pod number being 6.59% ，and the highest for double pod ration reaching 34.05% .Forquality traits，the variation coefficients ranged from 14.25% to 30.94% ，with soluble sugar content showing the lowest variation，and vitamin C content the highest.Chuanqi108，Yuquan No.3，andJiangshanmeihadthesmalest changes indensity，seedtopodfresh massratio， and weightlossration，respectively.Greycorelationanalysisrevealedthat19varieties，includingLixinNo.12and Tianyuanlifei，ranked higherthan thecontrolVarietyin termsofboth equal weightcorrelationandweightedcorrelation. Combinedcommodityanalysis，sixvarietiesincludingTianyuanluifei，Degang，NongfengNo.3，Youlemei，JingkeNo.12， and Nongfeng No.12 had shown excelent comprehensive performance.Insummary，six varieties including Tianyuanluifei canbe promotedandappliedas excellent facilitylong cowpea varieties inthe coastal areas ofGuangxi.
