Carrots (Daucus carota L.) are a globally important vegetable crop providing a source of important nutritional compounds through their carotenoid content whilst adding flavour and texture to many diets across the world. The current research focuses on the evaluation of sugars, vitamin C and dietary fibre content in ‘Nante’ hybrid carrots. The research was accomplished on fresh in Latvia cultivated carrots harvested in Zemgale region in the first part of October 2011 and immediately used for experiments. Late-bearing hybrids of ‘Nante’ carrots were used for analysis: Nante/ Berlikum, Nante/Maestro, Nante/Forto, Nante/Bolero, and Nante/Champion. The major sugars (fructose, glucose and sucrose) were determined by applying the method of high performance liquid chromatography, vitamin C - by titration with 0.05 M iodine solution, and dietary fibre - using standard method No 985.29. In the present experiments it was found that there are significant differences in the sugar, vitamin C and dietary fibre content between different carrot hybrids. The highest content of total sugars was found in Nante/Maestro and Nante/Champion 7.99 g 100 gE-1 and 7.57 g 100 gE-1 hybrids in fresh weight, respectively. The lowest total sugars content was in Nante/Berlikum hybrid − 4.03 g 100 gE-1. Vitamin C content in carrot hybrid Nante/Maestro was the highest 17.61±0.17 mg 100 gE-1, but in hybrid Nante/Champion - the lowest 8.39±0.17 mg 100 gE-1 of fresh weight. The dietary fibre content in analysed carrot samples ranged from 34.25±0.47 g 100 gE-1 in Nante/Maestro to 25.78±1.54 g 100 gE-1 in Nante/Champion hybrids.
