Correlation analysis of quality indexes and geographical coordinates and correlation analysis of the seven quality indexes were also performed. The results showed that: quality differences between Nagafu 2 apple from different habitats were obvious , especial!y for fruit index , peel color value , total acid content and TSS-Acid ratio. Correlation analysis of quality indexes and geographical coordinates revealed that: fruit index and fruit firmness showed negative correlation with longitude significantly; fruit firmness and total acid content showed positive correlation with altitude extrem巳ly significant; TSS-Acid showed negative corr巳lation with altitude significantly. It proved that growing location of the same apple breed affected fruit quality. Correlation analysis of the seven quality indexes revealed that: single fruit weight showed significant positive correlation with fruit index , soluble
