Abstract
Tomato (Solanum lycopersicum L.) is extensively cultivated warm season vegetable widely consumed around the globe both for table purpose and processing purpose. The present investigation entitled “Genetic variability studies in tomato” was carried out at the Vegetable Research Farm, Department of Vegetable Science, Dr. YS Parmar University of Horticulture and Forestry, Solan (HP) during Kharif, 2022. Thirty genotypes including check variety Solan Lalima were evaluated to ascertain the extent of variability, correlation and path analysis for yield and other horticultural traits along with estimation of genetic gain among genotypes. The experiment was laid out in Randomized Block Design with three replications. The present studies revealed significant variation among genotypes for all the traits. Where, it is recorded that SEL-26, SEL-22 and CLW-2174102 have performed superior over the check in various attributes. High genetic variability was recorded for fruit yield per plant and number of fruits per cluster. Followed by, moderate genetic variability was recorded for average fruit weight, plant height, number of locules per fruit, number of fruits per plant, number of seeds per fruit, pericarp thickness and fruit shape index. While low genetic variability was recorded for total soluble solids, days to 50% flowering, harvest duration and days to maturity. Fruit yield per plant was significantly and positively correlated with average fruit weight followed by number of fruits per plant, days to 50% flowering, days to maturity, plant height, fruit shape index, number of locules per fruit and harvest duration. Path analysis revealed that average fruit weight followed by number of fruits per plant had maximum positive direct effect towards fruit yield per plant
