Abstract
Purpose: creation of a new high-yield, mid-ripening, technological, with a high protein content soybean variety, responsive to irrigation and suitable for cultivation in crops without irrigation. Materials and methods. A collection of soybeans, numbering 2 thousand varieties of various ecological and geographical origin, including the selection of the Federal State Budgetary Scientific Institution VNIIOZ, created in 1983 and annually replenished with new genotypes. Hybridization and selection in later generations. The research was carried out on the chernozem soils of Volgograd region. Results. The original plant varieties were identified in the period 2008–2010, competitive variety trials were carried out in 2014–2016, state tests were held in 2018 and 2019. A new soybean variety called Volgogradka 2 has been included in the State Register of Varieties approved for use since 2020. In accordance with the indicators of its comparative with the standard characteristics, it stands out for its high yield (3.04 t/ha (an increase of 0.34 t/ha)), a short growing season (105 days), medium-sized (0.74 m) plants with a high attachment of lower beans (0.16 m), an increased protein content in seeds (41 %) and a gross crude protein and fat yield of 1.51 t/ha. It is drought-resistant in non-irrigated agriculture of the steppe zone of chernozem soils of Volgograd region, highly profitable and provides high-quality grain production suitable for food processing. Conclusions. A fundamentally new soybean variety with a complete type of stalk growth during the period of mass flowering, a low stem that is resistant to lodging and high attachment of lower beans, a short growing season, which contributes to a significant increase in the grain yield and quality in terms of protein content relative to standard varieties VNIIOZ 76 and VNIIOZ 86 was developed by traditional methods of breeding. The introduction of the new variety will allow expanding soybean crops in the Lower Volga region and increasing domestic soybean production.
