Abstract
The article presents the results of the study of biological and economically valuable traits of Brassica oleracea L. var. romanesco. During the study, samples of various varieties of Romanesco cabbage were evaluated based on phenological observations, and their growing season, number of leaves, morphometric indicators of leaf plates, and biometric characteristics of cabbage were determined and analyzed comparatively. The experiments were conducted during the summer sowing period, and soil moisture was maintained at 60–70% of field moisture capacity. According to the results, the growing season of the varieties varied within 120–132 days. The “Shannon” variety showed the shortest growing season, while the “Natalino” variety had the longest growing season. The “Zhemchuzhina” variety prevailed in terms of the number of leaves, and the “Veronika”
variety showed high results in terms of leaf length and width.
