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, genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were high for lycopene content, average fruit weight, number of fruits per plant, fruit yield per hectare, fruit yield per plant, titrable acidity, number of locules per fruit, number of primary branches per plant, ascorbic acid and plant height at maturity indicating high amount of variation for above mentioned traits in tomato revealed existence of broad genetic base, which would be amenable for further selection. High heritability (>60%) coupled with high estimates of genetic advance as percent of mean (GAM) have been observed for all the characters which is mentioned above except days to flower initiation, days to fruit initiation, days to fruit maturity at physiological stage, zinc content and iron content. This is indicating the presence of additive gene effect which may be utilized for improvement through phenotypic selection for yield improvement.
