Abstract： Using three linearpepper varieties，Layan12，Qianjiao8，andXianjiao301，fromfour productionareas—YanshancountyinYunnan，FuquancityinGuizhou，DalicountyinShaanxi，andLuohecityinHenanas experimentalaterials，thequalityoflinear chili pepper varieties was evaluatedbymeasuring eightkey indicators：Reducingsugars，crude fat，crudeprotein，crudefiber，aminoacids，capsaicin，diydrocapsaicin，andcapsanthin.Acomprehensiveevaluatiowas thenperformed usingcorrelationanalysisandprincipalcomponentanalysis.Theresultsshowedthatallqualityindicators were significantly influenced by production areas，with coefficients of variation ranging from 10.91% to 85.42% ，among which capsanthin content exhibited the highest CV. PCA comprehensive scores revealed that Layan 12 in Fuquan city rankedfirst witha scoreof1.96，while Qianjiao8in Fuquan cityand Dalicounty secured second and third places with scoresof0.92andO.70，respectively.Theenvironmentalconditionsofproductionareassignificantlyregulatedqualityfor mation，with Fuquan city demonstrating the most pronounced optimization effectonthequalityofLayan 12.These findings providea theoretical basis for regional selectionand high-quality cultivationoflinear pepper variety.
