Abstract: To comprehensively evaluate the nutritional quality of different apricot cultivars, and select those with good development and utilization potentials, we measured three appearance qualities (fruit shape index, fruit weight, edible rate) and eight nutrient indexes (soluble solid, soluble sugar, soluble protein, titratable acid, carotenoid, vitamin C, solid to acid ratio, sugar to acid ratio). The comprehensive quality evaluation of apricot cultivars was carried out by correlation analysis and principal component analysis. The results displayed that there were differences in the nutritional components of the 11 apricot cultivars, but the variation was not significant. Correlation analysis showed that there were highly and significantly positive correlations between fruit weight and edible rate, soluble solid and vitamin C, soluble sugar and sugar to acid ratio, solid to acid ratio and sugar to acid ratio. There were extremely and significantly negative correlations between titratable acid and solid to acid ratio, sugar to acid ratio. There were significantly positive correlations between titratable acid and solid to acid ratio, solid to acid ratio and sugar to acid ratio. Principal component analysis extracted four principal components, and the cumulative variance contribution rate was 91.002%, indicating that the main indexes affecting the quality of apricot fruit were: sugar to acid ratio, solid to acid ratio, edible rate, fruit weight, fruit shape index, soluble solid. This study can provide references for the selection and utilization of new apricot cultivars, and the quality of ‘Jinhebao’,‘Kaite’,‘Lanzhoudajiexing’,‘Wanhongxing’, ‘Youxiwanshu’are better.
