The correlation and path analyses for fruit yield and yield component characters were studied in twenty one diverse thermo tolerant tomato genotypes. Correlation studies indicated that fruit yield had positive and highly significant correlation with average fruit weight, fruit polar diameter, fruit equatorial diameter, fruit pericarp thickness and fruit set per cent at both phenotypic and genotypic level. Genotypic path analysis showed pollen germination per cent had maximum direct effect on fruit yield followed by average fruit weight, fruit set per cent and pericarp thickness. This indicated the scope for improvement through simple selection for these traits and it may be highly effective as these traits are less influenced by environment.
