“…According to other researchers, the contribution of meteorological conditions to the formation of crop yields was much higher, reaching 24%-55%. At the same time, the strong influence of the weather extends, among other things, to the main indicators of the quality of the resulting crop, such as protein and gluten content in grain, flour strength [5].…”

Current trends in climate change associated with the growth of heat supply contribute to the growth of bioclimatic potential and the increase in productivity of grain crops in the North-West of Russia. In such conditions, research is relevant aimed at clarifying the contribution of weather conditions and anthropogenic activity in the formation of the crop. The research was conducted on the crops of winter rye, spring barley, winter wheat, and spring wheat of the experimental landfill of the Menkovsky branch of the Agrophysical Research Institute. We studied various factors of anthropogenic activity, such as the level of mineral or nitrogen nutrition, an integrated plant protection system, seeding rates, and the size of seed material. Variance analysis was used in statistical processing. According to the results obtained, weather conditions were the most significant factor of productivity for winter cereals, and mineral nutrition was crucial for spring crops. The integrated protection system was less important than both the weather conditions of the growing season and the background of mineral nutrition of cultivated plants. This factor appeared to be the least significant for winter rye, which often has a favorable phytosanitary situation. The novelty of the data obtained lies in determining the predominant value in varying the yield of nitrogen fertilizers and herbicide treatment for spring wheat. A little less critical were the seeding rate and the size of the seed material.

The studies were conducted with the aim of a comprehensive assessment of spring soft wheat varieties of various maturity groups in terms of the level of disclosure of adaptive potential with the identification of valuable ones for use in breeding. The work was carried out in Ryazan region in 2018-2023. The material for the study was mid-early and mid-season foreign varieties Odeta, Sable, Kanyuk, Kalispero, KVS Torridon, KVS Aquilon, Ethos, CH Rubli, Etyud, as well as domestic varieties Zlata, Burlak, Agata, Gerakl, Omskaya 36, Margarita. Calculation of the parameters of adaptability, plasticity and stability was carried out according to the methods of A.A. Rossielle, J. Hemblin, L.A. Zhivotkov et al., E.D. Nettevich et al., V.A. Zykin, V.V. Khangildin. The soil of the plot is dark gray forest heavy loamy, of medium fertility. The weather conditions during the period were contrasting, typical of the Central Non-Black Earth Region. The yield of the mid-early group of varieties was within 3.57 ... 6.73 t/ha, mid-season - 3.33 ... 7.06 t/ha. High adaptive capacity was characterized by the mid-early variety Odeta, mid-season KVS Akvilon, Kanyuk, Kalispero, KVS Torridon. On average, over the years of research, their productivity was 5.51...5.95 t/ha, exceeding the average variety productivity in their maturity groups by 6.7...17.5%. At the same time, they had high indicators of compensatory capacity ((Y2+Y1)/2) - 5.62...5.95 t/ha, selection value (Sc) - 3.80...4.22 and variety stability level (VSL) - 103.2...156.2%. According to the comprehensive rating for the totality of all adaptability features, the best mid-early varieties were Zlata and Odeta with a rank sum of 21, mid-season varieties - Kanyuk, KVS Akvilon, KVS Torridon, Kalispero with a rank sum of 14...40.

The results of three-year studies (2020–2022) conducted in the forest-steppe zone of the Samara region in the agrocenosis of winter wheat are presented. The purpose of the work was to study the influence of natural and climatic conditions of the research area on the formation of yield indicators, protein content in winter wheat grain. The material was 10 varieties from the Vavilov All-Russian Institute of Plant Genetic Resources (VIR) collection and 5 varieties of selection of the Povolzhsky Scientific Research Institute of Selection and Seed Growing named after P.N. Konstantinov. Yield, grain protein content and protein yield per hectare were determined. Varieties characterized by high yield and high amount of protein in grain, showing maximum protein yield in different weather conditions of the years were identified. Over the years of research, the year 2022 was the most favorable for the formation of high yields (between 6 and 8.5 t/ha were harvested in the indicated year), where a large amount of precipitation was observed in May – the first ten-day period of June. The protein content in grain was the highest in 2021 (14–19%), when high temperatures were observed during the grain filling period in the absence of precipitation. For each variety, the correlation dependence of the sum of active temperatures and the amount of precipitation during the spring-summer vegetation period with the studied indicators was established. There was a negative correlation between the sum of active temperatures and yield (from –0.553 to –0.981) and a positive correlation with the protein content indicator (from 0.605 to 0.984) depending on the variety. The amount of precipitation was in a positive correlation with the yield index, the dependence on the protein content in the grain was ambiguous and depended on the variety. The studied indicators were influenced not only by natural and climatic conditions, but also by the genotypic features of the studied varieties, which explains the diverse correlation dependence.
