Two cultivars of cherry tomato (Conchita F1, Favorita F1) and large-fruited tomato ‘Cunero’ were grown on rockwool - Flormin under glass. Quality characteristics of fruits: dry matter, total sugars, vitamin C, total acidity, beta-carotene and lycopene contents as well as colour and hardness of fruits were determined. The results obtained showed that cherry tomato fruits had more dry matter, total sugars, higher ratio of sugars to acids and more vitamin C than large-fruited tomato. The average content of lycopene was similar in the two types of tomato but cherry type ‘Favorita F1’ had twice as much lycopene than ‘Conchita F1’. Beta-carotene content in fruits depended on the type and variety of tomato. Fruits of cherry tomato were less hard than large-fruited ones.
