“…One of the most important and timely topics of discussion is the upcoming climate change, both in the global project and in relation to the agriculture and crop production sectors [5][6][7]. A review of studies conducted in the last century revealed that in the continental climate of the Russian Federation, meteorological conditions are considered an important factor determining the average annual changes in the productivity of cultivated crops [8][9].…”

The studies were conducted in 2006-2022. in the Ryazan branch of the Federal State Budgetary Institution FNATS VIM. The object of research was released varieties and promising lines of Hordeum vulgare L. Sensulato. The purpose of the research is to establish the influence of changing weather conditions on the development phases and productivity of Hordeum vulgare L. Sensulato in the center of the European part of Russia. It was established that in the region there was an increase in the average daily air temperature during the growing season from 16.3 to 20.9°C (4.6°C/17 years, CV = 4.7%). The length of the growing season is closely related to the conditions of the hydrothermal regime of the year (r=+0.507...+0.508). The data obtained revealed a negative effect of the sum of air temperatures on the yield in the sprouting-tillering phase r = - 0.364, but the correlation with the amount of precipitation in this period was r = + 0.331, HTCM r = + 0.300. A closer relationship between the yield and the amount of precipitation (r=+0.308) and the hydrothermal coefficient (r=+0.337) is manifested in the interphase period of tillering and heading. The duration of the interphase period of germination-tillering has an average direct relationship with the HTC (r = +0.361) and a high inverse relationship with the sum of temperatures (r = -0.804), a similar picture is observed in the interphase period of earing-filling (r = +0.320 and r = -0.813 , respectively). The decisive weather factors that determine the size of the harvest and the duration of interphase periods of Hordeum vulgare L. Sensulato in the conditions of the Ryazan region are precipitation and thermal conditions from the second decade of May to the second decade of July.

Studies to evaluate new genetic forms of spring barley were carried out in 2020-2022. in the conditions of the center of the European part of Russia (Ryazan region) on the following varieties: Znatny, Pamyati Chepeleva (Russia); Kufal, Reider (Belarus); KVS Harris, KVS Vermont, Bente, Ellinor (Germany); LG Nabucco, Rapid (France); Laureate (Switzerland), regionalized in the period 2018-2020. It was established that the varieties Znatny - 6.38 t/ha, Ellinor - 6.02 t/ha and Kufal - 5.98 t/ha had the highest average yield. According to the length of the spike (≥8.0 cm), the varieties Bente and Znatny stood out. It has been established that the varieties Pamyati Chepeleva and Laureate have the highest productive bushiness (≥4.0), the varieties Kufal, Reider, Bente have a high grain size (≥50.0 g). According to a number of statistical indicators for assessing adaptability, the following varieties were identified: in terms of the level of yield and plasticity of the variety - Znatny and Ellinor (more than 100.0%); according to the coefficient of adaptability - Znatny, Kufal, KVS Harris, KVS Vermont, Ellinor and Rapid (K.A.> 1.0); in terms of phenotypic stability (1.22…1.58) – Bente, KVS Harris, Noble, Ellinor and Rapid; according to the level of homeostasis (> 0.30) - Bente, Noble and Ellinor; by the minimum value of the range of yield (<0.30) - Bente, KVS Harris, KVS Vermont, Noble; for the realization of the yield potential (≥ 80.0%) - Znatny, Kufal, KVS Harris, Bente and Ellinor; in terms of stress resistance - Bente, KVS Harris, Ellinor and Noble; according to the genetic flexibility of the variety - Noble and Rapid. The principle of ranking the best varieties made it possible to single out the varieties Znatny, Bente and KVS Harris, which took the first, second and third places in the rating scale, respectively. Analysis of the correlation dependence of adaptability indicators on the yield of new varieties revealed a significant contribution of the level of variety stability, adaptability coefficient, homeostatic level, realization of the yield potential of varieties and genetic flexibility (r = +0.502…+0.958).

Four varieties and 3 promising lines of spring barley breeding by Tatar Research Institute of Agriculture were studied for grain nutrition to identify the most promising ones. The work was conducted in 2015-2017 in Predkamye Republic of Tatarstan. Grey forest soil, humus content 3.35-3.52 % (GOST 26213-91), alkaline-hydrolyzable nitrogen 85.0...94.0 mg/kg (by A.H. Kornfield), mobile phosphorus 251...287 and exchangeable potassium 149...167 mg/kg (by Kirsanov; GOST 26207-91). The predecessor is winter rye, the repetition is fourfold, the standard grade is Raushan. It was found that line k-295-12, on average over 3 years, significantly exceeded the standard by 27.77 g in crude protein content; by 20.0 g in digestible protein content and by 7.35 g in digestible protein content per feeding unit. The variability of sugar content in varieties was 30.67 ... 47.0 g, significantly exceeded the standard by 13.33 g variety Tevkech (47.0 g) and by 13.0 g line k-23-13 (46.67 g). The fat content was formed in the standard 19.03 g, varieties Kamashevsky, Endan and lines k-23-23, k-561-13 and k-295-12 exceeded it by 7.47; 5.77; 11.47; 9.84 and 5.67 g, respectively. The exchange energy content in grain ranged from 14.42 MJ of the variety Raushan, to 14.72 MJ of the line k-295-12, with no significant differences between genotypes. In the dry year of 2015, the crude and digestible protein content was 148.0...165.0 and 110.74...118.8 g, respectively, and in 2016 it was 129.00...164.4 and 92.88...118.37 g, respectively. In favorable 2017, the content of crude and digestible protein were lower, the varieties Raushan and Tevkech were characterized by the greatest decrease in crude and digestible protein (65.7 and 67.4 % to the level of 2015). On average over 3 years, the best line was k-295-12 for the set of indicators of grain nutrition
