Abstract: A field experiment was conducted during rabi season 2017-18 in Randomized Block Design with three replications at Horticultural Research cum Instructional Farm, Department of Vegetable Science, IGKV, Raipur (C.G.). Six diverse and horticulturally superior lines of tomato were crossed with four testers in line x tester mating design. The resultant 24 hybrids (F1‘S) along with their parents (six lines and four testers) were evaluated for eighteen yield and yield attributing traits in tomato. The experiment results revealed that parents 2014/TOLCVRES-3 performed best for characters viz., number of flowers per cluster (6.38), number of fruits per cluster (4.84), pericarp thickness (mm) 6.18 mm and total soluble solid (°Brix) 4.49 °Brix. Fruit diameter (cm), average fruit wt. (g) and fruit length (cm) were observed in parents2015/TOLCVRES-2 and 2015/TOLCVRES-4.Whereas fruit yield per plant (3.78 kg), days to first fruit harvest (70.99) and dry matter % of fruit (6.21%) recorded in parent H-86. Among all parents, H-86 and 2014/TOLCVRES-3 with the yield of 659.72 q/ha and 611.04 q/ha respectively were found to be better yielders. Among all hybrids PR X 14/TLCV-3, PC X 15/TLCV-2, KA X 15/TLCV-2, KA X 14/TLCV-3 and AV X 14/TLCV-1 were best performing in maximum number of quality and yield attributing traits like days to 50% flowering (27.00), maximum number of fruit cluster per plant (12.42), ascorbic acid (25.01 mg/100g), number of flowers per cluster (7.12), fruit diameter 7.00 cm, average fruit wt. (144.50 g), fruit yield per plant (3.52kg), total soluble solid (5.71 ºBrix), and number of locules per fruit (5.24). Fruit yield per hectare was observed in the cross H–86 X 14/TLCV-3 (727.58 q), followed by KA X 14/TLCV-3 (724.13 q) and H–86 X 15/TLCV-4 (705.76 q). Therefore, recommended for generation advancement and selection of desirable progeny lines useful for Chhattisgarh plains.
