ABSTRACT
The genetic parameters were studied in F2 population of the cross IIHR-2201 X C-13-1-2-1 to elucidate the genetic variability, heritability and genetic advance in tomato (Solanum lycopersicum L.). The evaluation was carried out at experimental block, Department of Vegetable Science, College of Horticulture, UHS Campus, GKVK, Bengaluru during 2015-2016. Variability analysis showed the presence of sufficient amount of variability among all the traits studied in the segregating population. Very little differences were observed between genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) for all the characters except fruit firmness (kg/cm2) and TSS (0B) indicating that most of the traits were less influenced by environmental factors for their phenotypic expression. High heritability coupled with high genetic advance as per cent mean was observed for plant height, number of branches, number of fruits per plant, average fruit weight, pericarp thickness, number of locules, ascorbic acid and yield per plant indicating wide scope for improvement through selection of these traits. The exploration ofgenetic variability in the available germplasm is a prerequisite in a breeding programme for effective selection of superior genotype of tomato.
Key words: Tomato, Genetic variability, GCV, PCV, Heritability, Genetic advance.
