Abstract : The quality traits of mango resources were tested by correlation and fuzzy cluster analysis in Nujiang hot-dry valley. The results showed the resources had the abundant diversity, and the sequence of coefficient of variation was weight of single fruit (X1) > length of fruit (X2) > width of fruit (X3) > soluble solids (X6) > thickness of fruit (X4) > edible rate (X5). the extremely significant correlations between quality traits were observed except for that between X4 and X5. The correlation between X6 and X1, X2, X3, X4 were negatively significant at 1% level, the remaining were extremely and positively significant. With the fuzzy cluster analysis, 58 mango individuals in Nujiang hot-dry valley were divided into three classes according to their quality traits when ? was between 0.93 and 0.98.
