 ABSTRACT

Tomato [Lycopersicon esculentum Mill.] being an under exploited vegetable has a wide range of variability. Exploitation of hybrid vigour provides ample scope for improving the genetic architecture of tomato. The study material comprised of genetically diverse thirteen tomato genotypes which were evaluated in randomized block design. The genotypes were evaluated on the basis of plant height, number branches, days to 50% flowering, number of trusses per plant, number of flowers per cluster, number of fruits per truss, number of fruits per plant, leaf area index, marketable yield, average fruit weight, equatorial and polar diameter of fruit, number of locules per fruit, pericarp thickness of fruit, total soluble solids, acidity, ascorbic acid content ,chlorophyll a:b ratio, test weight of seed and days to first harvest, which differentiate the tomato genotypes. Analysis of variance studies indicated a significant difference among all the genotypes for all the characters under study. Genetic variability studies showed high PCV and GCV values for number of branches per plant, pericarp thickness and acidity indicating that a greater amount of genetic variability was present for these characters. High heritability coupled with high genetic advance as per cent of mean was observed for marketable yield, days to 50% flowering, plant height at 90 days after transplanting, number of fruits per plant, number of branches per plant, total soluble solids number of locules per fruit, which indicated that these traits were under the strong influence of additive gene action.

Keywords: Tomato, Variability, Heritability, GCV and PCV
