Abstract:
The present study on morphological and Physio-chemical characteristics of four crosses and seven genotypes of tomato were carried out during kharif 2021 at Western Block Farm, Horticultural College and Research Institute, Periyakulam of Theni District, Tamil Nadu. The experiment was carried out with three replications in Randomized Block Design. The aim of this study was to identify the tomato genotypes with superior morphological (fruit shape, fruit colour, fruit length (cm), fruit width (cm), average fruit weight (g), pericarp thickness (mm), number of locules per fruit) and Physio-chemical characteristics (fruit firmness (kg/cm²), total soluble solids (°Brix), ascorbic acid content (mg per 100 g) and titrable acidity (%). The derivative of cross Acc. 14 × Acc. 71 recorded the highest average fruit weight (69.53g), fruit firmness (2.27 kg/cm²) and pericarp thickness (5.44 mm), while that of Acc. 14 × PKM-1 was found to possess the highest number of locules per fruit (6.30). The cross PKM-1 × Acc. 90 exhibited the highest fruit width (5.13 cm) and total soluble solids (5.40°Brix). The highest ascorbic acid content was found in COTH 3 (37.08 mg per 100 g). With respect to titrable acidity, PKM-1, which is one of the parents recorded that the highest titrable acidity (0.87%).
