To select prospective genotype variants for future breeding programs, research is currently being done to evaluate the degree of genetic variability, heritability, and genetic progress among various tomato varieties using morphological features.

Experimental material comprising thirty-seven species of tomato genotype was raised in the three-replication using Randomized Block Design during the Rabi 2020-21 season and data were recorded in morphological and quality aspects. On the basis of mean performance of weight of fruits per plant, genotype superior to check genotype are 7053, 8105, 8202, 8623, 8730 as compared to the best checks 8716 and 9426. Analysis of variance (ANOVA) in Randomized Block Design experiments revealed significant for all morphological characters. The result showed higher phenotypic coefficients of variation of all characters compared to genotypic coefficients of variation. High Phenotypic Coefficient of Variation as recorded by fruit number per plant (38.07) followed by fruit weight per plant (33.49) and days to flowering (28.09) while high Genotypic Coefficient of Variation was identified by fruit number per plant (37.60) and followed by fruit weight per plant (32.94) and flowering days (27.52). All the characters showed high divergence. The number of fruits per plant showed high genetic advance (53.66) followed by maturity days (23.27) and plant height (20.73). The study provided an opportunity to identify genotypes and appropriate parameters like number of fruits per plant, days to plant height to be used in future breeding programs.
