Thirteen parental lines along with their 30 hybrid combinations produced by crossing in Line × Tester mating design were evaluated for heterosis and inbreeding depression of fruit quality traits and yield viz., total soluble solids (TSS), titratable acidity, ascorbic acid, fruit pH, lycopene, total sugars, reducing sugars, non-reducing sugars and total yield per plant. Highest heterotic effects for quality traits and yield over standard checks (SH1 and SH2) was observed for total yield per plant (kg) followed by titrable acidity (%), ascorbic acid (mg/100g), total soluble solids (ºBrix) and lycopene content (mg/100g). Inbreeding depression was also observed for different cross combinations. The crosses with significant heterosis in F1 could be used for the improvement of tomato for quality traits and yield.
