The BC2F3 tomato population of the cross GPBT-08 × CLN2768A was evaluated to measure genetic variability, heritability, genetic advance and character association. Analysis of variance for each trait showed significant differences among BC2F3. Analysis of variance showed significant differences for all the traits studied. The study revealed the estimates of phenotypic and genotypic coefficient of variation showed the presence of variability among the BC2F3 for branches per plant, fruits per plant, average fruit weight, plant height and number of clusters per plant. High genotypic and phenotypic co-efficient of variation was observed for number of branches per plant (34.36 and 37.74), fruits per plant (27.49 and 28.11), average fruit weight (27.42 and 27.96), plant height (27.31 and 28.10) and number of clusters per plant (26.02 and 27.68). Significant and positive genotypic and phenotypic correlation of fruit yield per plant was observed with plant height, number of branches per plant, umber of clusters per plant, number of fruits per plant, equatorial length of fruit and fruit shape index was observed. Hence, straight selection for these traits may bring worthwhile improvement in identifying superior genotypes in tomato.
