This article presents the results of studies of economically valuable traits and biochemical indicators of beetroot varieties and hybrids of domestic and foreign breeding in the conditions of south of Amur region. The germination of seeds of varieties and hybrids of beetroot ranged from 80% to 88%. The high field germination of seeds (88%) was shown by the beets of Primorskaya 4 variety. The Uspekh variety had lower marketability (83.9%) compared to other varieties, but was distinguished by a high average weight of root crop (294.7 g). The beet variety Valenta had a low average root weight of 168 g. The yield of beet varied from 30.0 t/ha (Detroit variety) to 44.3 t/ha (Pablo F1 variety). The maximum yield was formed in beet varieties Primorskaya 4 (37.9 t/ha), marketability 89.4%; Tsilindra (40.0 t/ha), marketability 90.2%; Pablo (44.3 t/ha), marketability 91.7%. A high organoleptic rating was given to the domestic varieties Primorskaya 4 and Uspekh. The most suitable variety for harvesting by a combine harvester was Primorskaya 4 variety, with an erect arrangement of leaves on the head of root crop. In terms of sugar content, this variety was also in the lead. The content of ascorbic acid in beet roots ranged from 6.53 mg/100 g (Uspekh variety) to 10.90 mg/100 g (Detroit variety), dry matter – from 14.39% (Pablo F1 variety) to 21.75% (Uspekh variety). The highest level of accumulation of coloring substances (betaxanthins and betacyanins) in beet root crops was noted for varieties Uspekh, Valenta.
