Abstract
22 local line chilli varieties of Guizhou were used to conduct quality analysis of different varieties and origin, along with correlation analysis and principal component analysis of different quality indicators, as well as comprehensive evaluation and cluster analysis of different varieties in this study. The results showed that the coefficient of variation of indicators related to pungency ranged between 103.05%-117.86%, and the difference of capsaicinoid-like substance was the largest among all quality indicators. Guizhou local line chilli had distinct characteristics of origin. Fruit from Anshun was large and long with largest size, flesh thickness and weight. Fruit from Bijie was thin and long with the least flesh thickness and weight. Fruit from Qiannan was thin and short. Moreover, certain correlations were also found among the product quality indicators, and the flavour quality indicators, as well as between the processing and commodity quality in Guizhou local line chilli. Among the 22 varieties, the comprehensive quality score of line chilli from Qiannan (named Pingtangxianjiao) was highest. The 22 local line chilli varieties of Guizhou were divided into 5 clusters with different fruit shape. Clusters I and II was classified as the ultra-long group, Cluster III was classified as the thin and long group, Cluster IV was classified as the thick and long group, and Cluster V was classified as the thick and short group. This analysis of the quality of Guizhou’s local line chilli will contribute to identify its origin and promote its creation and utilization.
