Abstract
A study was conducted to estimate heritability, genetic advance correlation between yield and yield components and fruit quality parameters in 50 tomato genotypes to establish the selection criteria in 2015-16 at Nuclear Institute for Agriculture and Biology (NIAB). Analysis of variance showed significant mean square for all that traits indicating scope of improvement in tested genotypes. High heritability and high genetic advance was observed in cluster per plant, plant height, fruit weight, vitamin C and protein contents proposed additive the gene action and early improvement of those traits via selection. Yield per plant was significantly and positively correlated with plant height, fruit weight, fruit width and fruit length suggesting improvement in yield via those traits. Flowers per cluster had highest direct positive effect on yield followed by fruit width, fruit length, plant height, fruit firmness and total carotenoids. So, keeping in view the results of heritability, genetic advance, correlation and path analysis yield can be increased by number of flowers, plant height, fruit width and length, fruit firmness, total carotenoids and vitamin C.
