Six genotypes of tomato were evaluated for yield and various yield attributing characters at the Main Experiment Station, Department of Genetics and Plant Breeding, School of Agricultural Sciences, G. H. Raisoni University, Saikheda Tah. Sausar Dist. Chhidwada (M.P.), India during 2022-2023. The experiment in Randomized Complete Block Design with three replications. Observations were recorded on twelve quantitative characters viz., days to 50% flowering, days to first flowering, plant height at 60 and 90 days after transplanting (DAT), fruit length (cm) count of primary branches per plant at 60 and 90 days, stem girth at 60 and 90 days, fruit diameter (cm), average fruit weight (g), days to first maturity, total yield per plant, fruit yield per plot, and Total Soluble Solids (TSS). Significant levels of Genetic Coefficient of Variation (GCV) and Phenotypic Coefficient of Variation (PCV) were evident across all traits, except for 'days to 50 percent flowering,' which exhibited minimal variability. High heritability, coupled with substantial genetic advancement as a percentage of the mean, was observed in all traits except for 'days to 50 percent flowering.' Notably, 'fruit yield per plant' ranked as the most prominent trait, followed by 'average fruit weight,' 'number of fruits per plant,' and 'plant height.' These top five traits displayed substantial genetic advancement, suggesting ample opportunities for enhanced selection responses.
