The present research programme, Genetic variability, heritability and genetic advance for yield and yield attributes in tomato (Solanum lycopersicum L.) was carried out at experimental farm of college of horticulture, Department of vegetable science, Sri Konda Laxman Telangana State Horticultural University, Rajendranagar, Hyderabad, Telangana, kharif, 2017-18. Forty tomato genotypes were evaluated in Randomized Block Design with three replications. Significant differences among genotypes were noticed in all characters. In the present investigation the high genetic variability observed for the characters number of primary branches per plant, number of fruits per plant, average fruit weight, fruit yield per plant and yield per hectare reveal the significance of these characters to be used for selecting superior genotypes. High heritability coupled with high genetic advance as per cent of mean shows operation of additive gene action which was observed in character’s plant height, number of primary branches per plant, days to 50% flowering, days to fruit set, number of fruits per plant, average fruit weight, fruit yield per plant, yield per hectare, ascorbic acid content, TSS, beta carotene and lycopene content which may be exploited for improvement through phenotypic selection for yield improvement.
