Under field conditions, during 2016, were studied 15 cultivars of tomatoes. When the fruit reached commercial maturity, the following quality indices were determined: water content and total dry substance (gravimetric method), soluble dry substance (refractometric method), titratable acidity (titrimetric method), total carbohydrates (Fehling Soxhlet method) and vitamin C (iodometric method). The best results on the quality of tomato fruits were obtained with the following cultivars: St. Pierre (7.33% total dry substance, 4.2% soluble dry substance, 0.67% acidity, 3.50% carbohydrate and 19.36 mg vitamin C), Caspar F1 (5.98% total dry substance, 3.8% soluble dry substance, 0.60% acidity, 3.20% carbohydrate and 21.12 mg vitamin C), Mirsini F1 (5.68% total dry substance, 4.0% soluble dry substance, 0.64% acidity, 3.30% carbohydrate and 21.12 mg vitamin C), Heintz (5.67% total dry substance, 3.7% soluble dry substance, 0.80% acidity, 3.10% carbohydrate and 24.64 mg vitamin C) and Darsirius (5.21% total dry substance, 3.9% soluble dry substance, 0.69% acidity, 3.20% carbohydrate and 19.36 mg vitamin C).
