Comprehensive Evaluation and Analysis of Dried Fruit Quality and Mineral Elements of 60 Different Germplasms of Lycium barbarum L.

Based on the differences and correlations of quality and mineral elements content in dried fruit of Lycium barbarum L., a comprehensive evaluation system was established to screen the excellent germplasms, also to provide theoretical basis for high quality breeding of Lycium barbarum L.. The 16 qualities and mineral elements content of dried fruit in 60 germplasms of Lycium barbarum L. were measured. The core evaluation indexes were screened by coefficient of variation, correlation analysis and factor analysis, and the comprehensive evaluation system of dried fruit quality of Lycium barbarum L. was constructed by analytic hierarchy process (AHP), grey correlation analysis (GCA) and cluster analysis (CA). The results showed that there were significant differences in nutritional components, constant element and trace element contents among different germplasms. There were significant positive correlations between total sugar content, betaine content and Zn content, polysaccharide content and Fe content, carotenoids content and Mg, Se content, flavonoids content and B, Zn, Ca content, fat content and Se, Mg content (P
