Friuts of nine Czech and Dutch indeterminate tomato cultivars were analysed for the content of selected nutritional compounds. Fresh fruits contained 6.4 percent of dry matter, 5.6 deg Bg of refractometric dry matter, 21 g/kg of glucose and fructose sum, 365 mg/kg of vitamin C, 144 mg/kg of total carotenoids, 2436 mg/kg of potassium, 152 mg/kg of calcium, 99 mg/kg of magnesium, and 28 mg/kg of sodium on average. Nutrional composition of tomato fruits was in most cases significantly dependent on cultivar and weather conditions during the cultivation period. A later fruit harvest had better nutritional quality. Cultivars: Domino and Tipo as well as Tornado and Toro showed a similar content of vitamin C and mineral elements. Fruits cv. Ultimo contained fewer mineral elements
