STUDIES ON VARIABILITY, HERITABILITY AND GENETIC ADVANCE IN TOMATO (SOLANUM LYCOPERSICON MILL.).

S.P. Gaikwad and M.N. Bhalekar

Abstract

A study was conducted to evaluate twenty five genotypes of tomato over two years in F5 and F6 generation at Department of Horticulture, Mahatma Phule Krishi Vidhyapeeth, Rahuri (M.S) to study the GCV, PCV, heritability and genetic gain for plant height, number of branches per plant, days to flower initiation, days to first harvesting, harvesting duration, number of harvestings, fruit yield per plant, number of fruit per plant, average fruit weight, average polar diameter, average equatorial diameter, pericarp thickness, number of locules per fruit, TSS and acidity per cent. In most of the characters for the genotypes in F5 and F6 generation the estimates of GCV were lower than PCV which suggested negligible role of environment in the expression of these traits. Higher heritability values were recorded for most of the traits in the genotypes for F5 and F6 generation. The higher estimates of heritability with high genetic advance were observed for most of the yield contributing characters.
