Correlation and path analysis was carried out in 60 tomato genotypes using growth, earliness, quality and yield characters. Very high (>40%) genotypic coefficient of variation (GCV) and phenotypic coefficient variation (PCV) were observed for fruit volume, average fruit weight and yield plant-1. It indicates existence of broad genetic base, which would be amenable for further selection. Very high heritability (>90%) coupled with very high genetic advance as per cent over mean (>40%) was recorded for the characters viz., polar diameter, fruit volume, average fruit weight, number of fruits plant-1, yield plot-1.Yield per plant was positively and significantly associated with average fruit weight, fruit volume, equatorial diameter, pericarp thickness, polar diameter and number of locules. Yield per plant was negatively and significantly associated with number of branches at 90 DAT, number of branches at 60 DAT, plant height at 90 DAT and plant spread from north to south at 60 DAT. Path analysis revealed that number of fruits per plant followed by plant spread from north to south at 60 DAT, plant spread from east to west at 60 DAT, average fruit weight and fruit volume. Hence, direct selection for these traits is suggested for yield improvement.
