Abstract : An experiment was carried out with 9 mango cultivars at Varietal Block of Horticultural Research Station, Mondouri, BCKV, Nadia, W. B. with Randomized Block Design to determine the genetic variability and correlation coefficient for among different fruit physico chemical characteristics. Among the various different characters the lowest range was recorded with acidity and it was highest for weight. Phenotypic co-efficient of variation was more than that of genotypic counter part for each of the characteristics. The estimated heritability showed a wide range of variation, i.e., 37.10-95.41 per cent. The genetic advance as percentage of mean also revealed high degree of variation (9.03-33.93). Magnitude of all most all correlation of genotype coefficient was more than that of phenotypic correlation coefficient. There was a significant positive correlation of fruit weight with pulp content, breadth and significant negative co-relation with peel and acid content. Total soluble solids (TSS) showed high positive correlation with total sugar and non reducing sugar. Whereas, acidity showed high negative correlation with non reducing sugar, fruit weight, pulp content, TSS, Sugar and reducing sugar content. These selection criteria indicated the basis for further improvement of mango.
