Abstract: The experiment was carried out during the period 2018-2020 with six varieties of sweet pepper grown under greenhouse and open field conditions on the territory of the seed production company “Superior D.O.O” in Velika Plana, Republic of Serbia. A genotypic expression of dry matter and cellulose was found in both cultivation variants. In the case of field pepper, a tendency to equalize the varieties in terms of the studied chemical composition was observed. Fruits from the field had higher values of ascorbic acid by an average of 40 mg% and a higher concentration of total pigments which was visually expressed as more intense and more homogeneous colour. The majority of varieties grown as greenhouse production were characterized by a lower cellulose content. The studied factors did not effect significantly on the quantity of total sugars. With the exception of Corno di Toro Rosso, the varieties included in the experiment showed good nutritional quality increasing in outdoor cultivation.
