Heritability Studies in Tomato (Lycopersicon esculentum L.) Genotypes

Abstract

Genetic variability, heritability, and genetic advance for fruit yield and quality traits in tomato (Solanum lycopersicum L.) were examined at Main Vegetable Research Station (MVRS) of Anand Agricultural University, Anand, for the kharif-rabi season of 2022-23. The experimental material is made-up of six families developed for generation mean analysis from nine diverse parents viz., 2012/TODVAR-1, AVTOV 1007, GAT-5, 2015/TOLCV RES-1, 2014/TOOV-10, 2016/TOV-10, 2017/TOLV-4, and 2015/2016/TOLCV RES-4. The results show that family I, II, III, and family V exhibited higher values of broad sense heritability with higher genetic advance, was a positive indication of presence of additive gene action and suggests selection methods for improvement of this trait via selection procedures. Higher values of genetic advance were reported highest for lycopene content (452.67 %) for family I and (212.85 %) for family III, 1000 seed weight for family V. This study suggests that improvement of yield and associated traits in L. esculentum should be focused on character basis and requirement of breeding programs.
