Abstract: 【Objective】 In order to provide theoretical references for comprehensive fruit quality evaluation of different pomegranates in Xinjiang.【Method】Six pomegranate cultivars were used as the tested materials to determinate the content of soluble solids, soluble sugar, titratable acid, and VC. The fruit quality of different pomegranate varieties was comprehensively evaluated by using principal components analysis.【Result】Results showed that there are some differences in fruit quality among different pomegranate varieties, and the soluble solids content of 'Yechengdazitianshiliu' was the highest (17.9%±0.6%); 'Kashisuanshiliu' had the lowest soluble solids content (14.9%±0.5%); 'Yechengtianshilu' had the highest titratable acid content (2.19%±0.38%); there were no significant differences among 'Yechengsuanshiliu', 'Kashitianshiliu' and 'Kashisuanshiliu' in titratable acid content. The soluble sugar content of 'Yechengtianshiliu' was (17.9%±0.6%), which was significantly higher than those of other five pomegranate cultivars; 'Piyamanshiliu' had the highest vitamin C content (28.3±1.1) mg/100 g, which was significantly higher than those of other pomegranate cultivars.【Conclusion】Through principal component analysis, we concluded that 'Yechengdazitianshiliu' had the best fruit quality, followed by 'Yechengtianshilu', 'Piyamanshiliu' and 'Yechengsuanshiliu' and 'Kashisuanshiliu'.
