В. В. Епифанцев The article presents the results of testing of table beet varieties and hybrids in the fields of farm private enterprise “S.E.V.” (Blagoveshchensk district, Amur region) in 2015–2017. It was shown that the growing season of varieties and hybrids depended on the conditions of the year by 11.3% and on the genotype by 4.3% to 10.3%, and the yield by 26.05% to 49.69% and 16.12% to 17.69%, respectively. The correlation between yield and growing season is inverse mean r = –0.659. Yield structure analysis showed that the yield of marketable root crops depended on their weight and number per unit area. Statistical analysis showed a direct mean correlation between the yield and the mass of marketable root crops r = 0.568 and an inverse strong correlation r = –0.728 between the yield and the number of root crops. The data obtained indicated a high productivity potential for the Bordo 237 varieties and the Tseppo F1 hybrid, with average yields ranging from 33.39 t/ha to 37.59 t/ha. All varieties and the hybrid have high yields of marketable root crops and good taste. Earlier varieties accumulate more nitrate in root crops, and hybrids of foreign selection have more nitrate than domestic ones.
