Abstract

Assessment of the stress resistance and productivity potential of soybean varieties in the Primorsky Krai. E.S. BUTOVETS, L.M. LUKYANCHUK, Е.А. VASINA (Federal Scientific Center of Agrobiotechnology in the Far East named after A.K. Chaika, Ussuriysk, Timiryazevsky village).

The article presents the results of evaluating soybean varieties of various origins and identifying promising samples in terms of yield and adaptability to the conditions of Primorsky Krai. It was found that to form the high percentage of protein content in soybeans, abundant precipitation with short-term periods of waterlogging is required in the second half of August and the first half of September. As a result of the immunological assessment, varieties with a high degree of resistance to cercosporosis and downy mildew were identified. Resistance to stress in Russian varieties of the Far Eastern selection was confirmed. Favorable conditions for realizing the productivity potential of soybean varieties were in 2020, where the environment index was the highest positive value (6.8). The selected varieties of soybeans due to the number of traits and parameters can be recommended for cultivation and inclusion in the breeding program.
