Estimates of heritability in narrow sense and genetic gain for different characters in tomato (Solanum lycopersicum L.)

Author(s):
Nishakant Maurya and GC Yadav
Abstract:
The investigations were carried out to evaluate the 47 genotypes (35 F1 and 12 parental lines) of tomato (Solanum lycopersicum L.) at Main Experimental Station, Department of Vegetable Science, A.N.D. University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) in a set of seven lines and five testers during Rabiigh es 2019-20 and 2020-2021. The experiments were laid out in Randomized Complete Block Design with three replications. The data were recorded for 17 characters including total fruit yield per plant and its component traits. Htimate of heritability in narrow-sense (>30) was recorded for total sugar in both the years and pooled while high genetic advance in per cent of mean (>20%) was observed for total fruit yield per plant followed by plant height, average fruit weight, number of locules per fruit in both the years. High heritability (narrow sense) coupled with high genetic advance as per cent of mean suggested that selection would be highly effective and efficient for these characters.
