Abstract

Broccoli cabbage Brassica oleracea L. var. italica is an economically important and widely cultivated vegetable crop, consumed both fresh and processed. To solve the problems of import substitution, the provision of high-quality varietal diversity of broccoli for agricultural producers in the middle zone of Russia and the Southern Federal District (SFD) comes first. Our work presents the results of the study of seven varieties and hybrids of broccoli, previously identified by productivity and commercial qualities. For the first time in the conditions of the northern dry subtropics of southern Dagestan, the content of dry matter, water-soluble polysaccharides, organic acids, flavonoids and antioxidant activity in fresh products were determined. The distribution of these substances by plant organs is shown. Broccoli samples with a high content of individual chemicals, as well as a set of characteristics that can be used as sources in breeding for an increased content of dry matter, water-soluble polysaccharides, organic acids, flavonoids and with high antioxidant activity, were isolated.
