Abstract : An experiment was conducted for 2 consecutive years [India; date not given] in 12 genetically diverse strains or varieties of mango to determine their inter-relationship among different characteristics and their effects on fruit weight. The genotypic and phenotypic correlation coefficient values revealed that the genotypic correlation coefficients were higher that their corresponding phenotypic correlation coefficients suggesting a strong inherent relationship among different genotypes. Fruit weight had highly significant and positive correlations with fruit length, fruit diameter, fruit volume and seed stone length during both years. It also exhibited positive but non-significant correlations with shoot length, leaf width, petiole length, panicle diameter, seed stone weight and seed stone diameter during both years. Shoot diameter, leaf length and reducing sugar also exhibited positive but non-significant association with fruit weight (only for one year). Path coefficient analyses for both years revealed that the direct effects exhibited by fruit length and volume were considerably positive. Shoot length, leaf width, panicle diameter, seed stone length and seed stone diameter also exhibited positive effect on fruit weight during both years. However, malformation and acidity showed positive but non-significant direct effects on fruit weight for both years.
