Analysis of Quality Traits of Different Pepper Germplasm Resources
The quality traits of 36 local pepper germplasm resources in Shandong were analyzed by variance analysis, coefficient of variation analysis, membership analysis and cluster analysis of different fruit shapes, regions and cluster categories. The results showed that the varia-tion 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%). In different fruit shapes, the average value of crude fiber content was significantly different be-tween groups(P=0.013∗). The coefficient of variation of linear pepper was the largest(165.22%). The average membership degree of the five quality indexes was between 0.18 and 0.65, and the comprehensive quality was quite different. The average membership degree was more than 0.60, and the top three pepper germplasm resources were ranked from large to small as follows : L949(0.65)= L958(0.65)> L951 (0.64)> L933(0.61)= L945(0.61)= LP220(0.61);the six pepper germplasm materials have good quality traits and can be used in medic-inal, feeding and food processing industries.
