Abstract：Using three linear pepper varieties,Layan 12,Qianjiao 8,and Xianjiao 301,from four production areas—Yan-shan county in Yunnan,Fuquan city in Guizhou,Dali county in Shaanxi,and Luohe city in Henan—as experimental mate-rials,the quality of linear chili pepper varieties was evaluated by measuring eight key indicators:Reducing sugars,crude fat,crude protein,crude fiber,amino acids,capsaicin,dihydrocapsaicin,and capsanthin.A comprehensive evaluation was then performed using correlation analysis and principal component analysis.The results showed that all quality indicators 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 ranked first with a score of 1.96,while Qianjiao 8 in Fuquan city and Dali county secured second and third places with scores of 0.92 and 0.70,respectively.The environmental conditions of production areas significantly regulated quality for-mation,with Fuquan city demonstrating the most pronounced optimization effect on the quality of Layan 12.These find-ings provide a theoretical basis for regional selection and high-quality cultivation of linear pepper variety.
