Relevance. In the context of improving food security and according to the development strategy of the grain complex of the Russian Federation, crop capacity quality increase of wheat grain remains a priority. It is significant to research winter wheat varieties selected in different geographical selection centres, in specific soil and climatic conditions, in order to identify their genetic potential.Methods. The research was conducted in 2015–2021 in the south-west of the centre of Russia. The object of the research was a set of 12 modern winter wheat varieties cultivated by intensive technology on grey forest soils in the Bryansk region.Results. Due to its genetic potential, each of the varieties has shown its responsiveness to the prevailing weather conditionsue to their geographical origin, there was a significant variation in crop capacity of the varieties Moskovskaya 40, Moskovskaya 56, Mera, Lgovskaya 8, Amelia. The varieties by Belarusian selection showed the maximum average yield (8.41 t/ha). The varieties under study formed coarse grain. However, such varieties as Nemchinovskaya 57, Poem, Elegy, Moskovskaya 56 should be attributed to the most stable ones, characterized by the minimal variation of this descriptor over the years. All varieties of winter wheat, with the exception of Lgovskaya 4 and Lgovskaya 8, formed the grain of the first class by the basal grain-unit. The "year" factor made the greatest contribution to the change in the protein (47.5%) and gluten content (57.5%) in grain. Among the varieties of Belarusian and Russian selection, Amelia (CV = 5.7%) and Moskovskaya 39 (CV = 12.3%) varieties can be distinguished as those forming stable highprotein grain with a high gluten content.
The collective monograph of the Library "Kuzbass Strategy" presents the main factors that shape the human potential of Kuzbass. The main historical stages of the development of labor resources in the region are considered. The results of the analysis of the development of the education system, health care, culture, sports, social sphere, entrepreneurship and employment of the Kuzbass population are presented. The main strategic priorities for the development of the human potential of Kuzbass to 2035 are outlined.
The article shows the results of a comparative assessment of grain productivity and adaptability parameters of early- ripe maize hybrids in the South-West of non-chernozem region (Bryansk region). The aim of this work is to study and evaluate the productive and adaptive potential of early- ripe maize hybrids in the agroclimatic conditions of the non-chernozem region. 22 hybrids of the early- ripe group (FAO 100-200) were taken as the object of research. The tasks of agroecological examining for the period 2016-2019. included an overall assessment of adaptive properties of studied maize genotypes in terms of environmental stability and plasticity, using the “yield” criterion. The features of the production process of maize seeds depending on changes in meteorological conditions of cultivation for the years of examining were studied, which allowed us to assess objectively the level of variation in the grain yield. We calculated the following indicators: index of environmental conditions (Ij), parameters of environmental plasticity - stability (Sd2) and plasticity (bi), stress resistance, yield span (d), ultrastability (Hom), variation coefficient (V). As a result of examining carried out over 4 years, the yield of maize grain varied from 6.02 t / ha of the LG 2195 hybrid of Limagrain Europe selection (France) to 8.69 t/ha of the Ladoga 181 MV hybrid (NGO “Kuban Seed Production”). According to the set of adaptability parameters, hybrids of domestic selection Ladozhsky 181 MV, Ladozhsky 191 MV, Krasnodar 194 AMV and foreign selection - P7954 (Pioneer, France) and Cromwell (KWS, Germany), which have stability, selection value, stress resistance and high productivity of grain in agro-landscape conditions of the Bryansk region were noted.
