Abstract:
A study was conducted at Vegetable Research Farm, DRPCAU, Pusa, Samastipur, Bihar during rabi 2015-16 to evaluate the genotypes of tomato (Solanum lycopersicum L.) for yield and quality. Investigation was carried out on variability for different morpho-physiological characters of 24 genotypes which were grown in Randomized Block Design with three replications. In the present investigation, character association among the yield and yield attributing traits and identify better combinations as selection criteria for developing high yielding tomato genotypes. Fruit yield per plant was positively correlated with number of primary branches per plant, equatorial diameter, polar diameter, number of fruits per plant, average fruit weight, total soluble solid, days to first flowering and titrable acidity suggesting that selection based on these characters would result better genotypes with higher yield. Among them number of primary branches per plant, equatorial diameter, polar diameter, number of fruits per plant were highly significantly correlated with yield per plant and average fruit weight and total soluble solid significantly correlated with yield per plant. Path coefficient analysis study revealed positive direct effect for plant height at maturity, number of primary branches per plant, days to first flowering, days to fruit maturity at physiological stage, polar diameter, number of locules per fruit, number of fruits per plant, average fruit weight, total soluble solid, titrable acidity and ascorbic acid on fruit yield per plant and selection based on these 18 characters would be more reliable for yield improvement.
