Abstract: The study was carried out to investigate the yield and horticultural quality traits in tomato, in order to generate information regarding the extent of genetic variability, heritability and genetic gain within the tomato genotypes. The experiment was laid out during 2015-2016 in Randomized Complete Block Design (RCBD) at an experimental farm of the Department of Vegetable Science, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Solan (HP). Totally twenty five genotypes of tomato with three replications were considered for genetic variability study. Analysis of coefficient of variation revealed that, the magnitude of phenotypic coefficient of variation was slightly higher than the genotypic coefficient of variation for all the studied traits. Further, High heritability along with high estimates of genetic gain was observed for number of fruits per cluster, number of seeds per fruit, average fruit weight, fruit yield per plant and fruit yield per hectare. Thus, indicating direct selection for these traits as a criteria for improvement in tomato.
