Abstract

Agenetic parameters like range, mean, phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV), heritability, genetic advance as percent of mean was studied in tomato genotypes. All the characters studied revealed high PCV than GVC which indicates that there is less influence of environment on alteration of these characters. The high heritability has been observed for the plant height, number of flowers per truss, number of flower trusses per plant, fruit length, fruit diameter, fruit shape index, pericarp thickness, total soluble solids, average fruit weight, fruit firmness, number of fruits per plant and yield per plant. Hence, these character could be improved by simple selection. The genotypes EC-608406 BRML, IIHR-709, Arka Ashish, Vybhav, IIHR2388, EC-608395, IIVR-L, CLN 2123A and EC-608456 2 were the top ten high yield genotypes with respect to fruit quality and fruit yieldper plant based on mean performance intomato.
