Abstract:
The present investigation entitled “Studies on genetic variability in tomato (Solanum lycopersicum L.) for growth, yield and quality traits” was carried out at the Experimental Farm, Department of Vegetable Science, Dr YSR Horticulture University, Venkataramannagudem, (AP) during Rabi season of 2020-21, to evaluate fourty five diverse genotypes of tomato in RCBD model replicated twice. Amongst the various parameters of variability, high phenotypic and genotypic coefficients of variability were recorded average fruit weight followed by lycopene conten, seed:pulp ratio, fruit firmness, shelf life, number of primary branches per plant, number of locules per fruit and pericarp thickness and high heritability coupled with high genetic gain was observed for average fruit weigh. While, high heritability along with moderate genetic gain was observed for plant height at 90 DAT, days to 50 percent flowering, average fruit weight, days to first harvest and days to last fruit harvest, indicating a wide range of variation and offered better scope for improvement through selection.
