Abstract : Fourteen collections of mango (Mangifera indica) were studied for their genetic variability and correlation among various fruit characters. The genetic and phenotypic coefficients of variance, heritability, genetic advance and coefficient of correlation were estimated for 15 fruit characters which included length, breadth, peel, pulp, stone, and contents of total soluble solids, sugars, ascorbic acid, carotenoids along with quality. A remarkable level of variability was observed among collections for these characters. All the characters showed higher estimates of broad-sense heritability, whereas genetic advance was very high for carotenoids, fruit weight, volume of fruit and ascorbic acid. Fruit weight, fruit length, fruit breadth, fruit pulp and overall quality were found to be effective selection indices.
