摘　　要：为充分了解山东地区辣椒种质资源的品质状况,对所收集的36份山东地方辣椒种质资源的品质性状进行了方差分析、变异系数分析和聚类分析。结果表明,不同辣椒种质资源材料间品质性状变异系数为14.37%~110.26%,辣椒素含量变异系数最大(110.26%);欧氏距离98.3处,可将36份辣椒种质资源聚为三大类群:第Ⅰ类群占5.56%;第Ⅱ类群占8.33%;第Ⅲ类群(TT)占比最大,高达86.11%。聚类分析表明,抗坏血酸和辣椒素在聚类间差异达极显著水平,聚类第Ⅰ类和第Ⅲ类,辣椒素变异系数均最大,第Ⅱ类粗蛋白变异系数最大。综上,第Ⅰ类群除鲜食、制酱外,可加工用作食品、化妆品、药品等产业中的重要添加剂;第Ⅱ类群经提取加工可用于医学药用和家禽畜牧饲用,可作为工业辣椒品种选育的优异材料;第Ⅲ类群利用度广泛,可普遍适用于鲜食、制酱、火锅和调料等食品加工产业等。In order to fully understand the quality of pepper germplasm resources in Shandong Province,the quality traits of 36 local pepper germplasm resources in Shandong Province were analyzed by different variance analysis,coefficient of variation analysis and cluster analysis.The results showed that the variation coefficient of quality traits among different pepper germplasm resources ranged from 14.37%to 110.26%,and the variation coefficient of capsaicin content was the largest(110.26%).At the Euclidean distance of 98.3,36 pepper germplasm resources could be clustered into three groups:the first group accounted for 5.56%;groupⅡaccounted for 8.33%;groupⅢ(TT)accounted for the largest proportion,up to 86.11%.Further analysis of the cluster showed that the difference between ascorbic acid and capsaicin was extremely significant,and the coefficient of variation of capsaicin was the largest in groupⅠand groupⅢ,and the coefficient of variation of crude protein in groupⅡwas the largest.In summary,group I can be used as an important additive in food,cosmetics,pharmaceutical and other industries in addition to fresh food and sauce.The groupⅡcan be used for medical medicine and livestock feeding,and can be used as an excellent material for industrial pepper variety breeding.GroupⅢhas a wide range of utilization and can be widely used in food processing industries such as fresh food,sauce making,hot pot and seasoning.
