Abstract: The investigation on “Genetic variability studies in F2 generations of tomato (Solanum lycopersicum L.)” was conducted in the field of Vegetable Science of Kittur Rani Channamma College of Horticulture, Arabhavi. Two F2 populations of tomato i.e., Arka Samrat and Arka Rakshak were evaluated in un- replicated yield trails during rabi 2015. Analysis of variance revealed that highly significant (P= 0.01 &P= 0.05) difference among two populations was observed for all characters studied indicating the higher magnitude of variability in two populations. High GCV and PCV were observed for plant canopy and lycopene content in both the populations. Except yield per plant in the population of Arka Samrat and number of primary branches per plant in the population of Arka Rakshak. The high heritability coupled with high GAM were observed for plant height, number of primary branches, plant spread from north to south direction, plant spread from east to west direction, plant canopy, polar diameter of fruit, equatorial diameter of fruit, pericarp thickness, number of locules per fruit, average fruit weight, number of fruits per plant, yield per plant, lycopene content and ascorbic acid in both the populations. Therefore, additive component is predominant here. Thus, there is ample scope for improving these characters through direct selection. The results on correlation and path analysis revealed positive and significant association of yield per plant with plant height, plant spread from east to west, plant canopy, average fruit weight, number of fruits per plant, plant spread from north to south, ascorbic acid and lycopene content, since these traits had high positive direct and indirect association with yield per plant. Hence, direct selection of these traits would be more useful in the improvement of yield per plant. The more number of fruits and high fruit yield per plant was recorded for the plant number 49, 153, 154, 213 and 217 in Arka Rakshak and 20, 22, 59, 120 and 141 in Arka Samrat and these plants forwarded for further generations to assess for their stability.
