Different genotypes are to be classified into clusters based on genetic diversity for any plant improvement programme. Further the extent of genetic divergence between them needs to be estimated. D 2 statistics is one of the powerful tools to assess the relative contribution of different component traits to the total diversity, to quantify the degree of divergence and to choose genetically diverse parents for obtaining desirable recombinants. The present study was conducted at Horticultural College and

Thirty mango genotypes were studied to find out their variability, heritability, and genetic advance. Significant variations were observed in 46 characters. There were also considerable differences between the genotypic and the phenotypic coefficients of variation for almost all the characters which indicated the influence of environment on the expression of these traits. Among the studied characters, GCV and PCV were high for 40 characters. All the characters showed considerably high heritability except leaf width which ranged from 21.32 to 99.85 % and the genetic advance (as % of mean) was high for 44traits. High heritability coupled with high genetic advance was observed in 44 traits except leafwidth and chlorophyll content which indicated that these characters were less influenced by environment confirming predominance of additive gene action and therefore, selection in favour of these 44 characters would be feasible for yield improvement of mango.
