The aim of this work was to evaluate 28 carrot genotypes, 5 parsley genotypes, 7 table beet genotypes and 15 onion genotypes and their content of dry matter, reducing sugars and carotenoids. The mean dry matter content in roots of carrot, parsley, table beet and onion bulbs was 13, 24, 16 and 13% and the content of reducing sugars was 104, 93, 111 and 90 g/kg, respectively. Mean carotenoids content in roots of carrot and table beet was 86 mg/kg and 2 mg/kg, respectively. Significant positive correlations (r = 0.43–0.86) between dry matter and sugar content in all species were found.
