Abstract:8 blueberry germplasm resources，planted in the hilly region of southern Anhui，were studied in this research.Analysed the quality traits and distribution of blueberry fruits.Using principal component analysis（PCA）and cluster analysis （CA）to set up a comprehensive evaluation model for quality comprehensive evaluation.The results showed that different degree of difference exist in fruit quality traits.Variation coefficients of fruit weight，volume，pH value，solid/acid ratio，and the contents of fruit seed，total acids，pectin，phenol，flavonoids，anthocyanins were all greater than 10% ，indicating high difference between varieties.Meanwhile，variation coefficients of hardness，fruit shape index，juice rate，water content，total solu－ble solids，reducing sugar content，vitamin C（VC）content and tannin content were less than 10%，which were small difference between varieties.5 main composition were extracted by pcomponent analysis，accumulative variance contribution was 92.261%.According to the main quality indexes of blueberry，the system cluster analysis of 8 blueberry varieties was carried out.And the results of CA were basically consistent with the results of the PCA.Comprehensive evaluation of blueberry quality showed that gardenblue and powderblue were high quality varieties，which could be used as a high-quality raw material for blueberry breeding，variety improvement and processing.
