Abstract : A study on the correlation of fruit characteristics of 69 types of mango cv. Langra was conducted. Results revealed that correlation at the genotypic level was higher than in the phenotypic level, indicating the strong correlation of characters genetically and the lowering effect of environmental interaction at the phenotypic level. Fruit length, fruit diameter, stone weight, peel weight, pulp weight and pulp percentage showed highly positive and significant genotypic and phenotypic correlation with fruit weight. Fruit weight showed the highest positive and significant genotypic and phenotypic correlation with pulp weight. Selection indices based on fruit size (length and diameter) with high pulp content were the most important factors for identifying high fruit weight types. Stone weight showed a strong and positive correlation with the peel weight. Fruit length was found to be negatively and significantly correlated with total soluble solids content and total sugar, but was positively correlated with fruit acidity, pulp weight and peel weight.
