The genetic parameters were studied to elucidate the genetic variability, heritability and genetic advance in tomato (Solanum lycopersicum L.). Field evaluation of F6 recombinant inbred lines was done. The genotypes exhibited a wide range of variability for all the characters studied. Phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) for all the characters studied. High heritability combined with high genetic advance was observed for the characters Average fruit weight (g), Number of branches per plant, Number of fruits per plant, Plant height(cm), Fruit yield per plant (kg), Total soluble solid (0Brix), Number of locules/fruit and Pericarp thickness (mm). High heritability combined with high genetic advance indicates that additive gene action plays a major role in governing these traits and these traits can be improved by simple selection.
