Cluster Analysis of Quality Traits of Local Pepper Germplasm Resources in Shandong Province
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 re-sources could be clustered into three groups:the first group accounted for 5.56％;group Ⅱ accounted for 8.33％;group Ⅲ( 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 ex-tremely significant, and the coefficient of variation of capsaicin was the largest in group Ⅰ and group Ⅲ, and the coefficient of variation of crude protein in group Ⅱ was 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 group Ⅱ can be used for medical medicine and livestock feeding, and can be used as an excellent material for industrial pepper variety breeding. Group Ⅲ has a wide range of utilization and can be widely used in food processing industries such as fresh food, sauce making, hot pot and seasoning.
