“…An analysis of the contribution share of the "combination of fertilizers" factor showed that it accounted for 75.95%. There is evidence in the papers that as a variety's potential productivity increases, the environmental stability of the crop decreases (Goncharenko, 2016). The interactions of factors, -conditions of the agricultural year‖ and -combinations of mineral fertilizers,‖ reflect a smaller share: 19.24%.…”

The article presents the results of a study in the agrocenosis of soft winter wheat to determine the effects of pre-sowing and early spring application of various forms and combinations of nitrogen, phosphorus, and potash fertilizers when growing it in the leached chernozem of the Western Ciscaucasia. The soil is characteristic of a satisfactory state of the structure, density: 1.26–1.42 g/cm3; active acidity (pH): 6.29– 6.58 pH; exchangeable (pH): 5.11–5.25 units; hydrolytic: 1.94–3.05 meq/100 g; the amount of absorbed bases: 27.5–31.2 meq/100 g; cation exchange capacity: 30.6– 33.1 meq. /100 g; the soil saturation degree with bases: 90.2%–94.3%; and humus content: 2.93%. Fertilizers improve the nutrient regime of the soil. The average supply level with mineral nitrogen, high and mobile phosphorus, and very high mobile potassium has been well-defined. It could lead to an increase in grain when applying N120P30K60 - 1.28 t/ha (or 24.1%), N120P90K20 - 1.47 t/ha (or 27.8%), and N120P90K60 - 1.53 t/ha (or 28.8%). The grain yield of soft winter wheat was 6.58, 6.77, and 6.83 t/ha, respectively. The protein content in the grain varied from 13.2% to 14.3%. The collection of protein per hectare was 870.5, 948.5, and 958.3 kg/ha for the treatments N120P30K60, N120P90K20, and N120P90K60, respectively. The protein in the control was equal to 554.9 kg/ha. Dispersion analysis of the study results showed the share of the contribution of the factor "combination of fertilizers" was 75.95%. Similarly, the data analysis of the conditions of the agricultural year and combinations of mineral fertilizers has a smaller share - 19.24%. With the introduction of N120P30K60 and N120P90K20, the payback of mineral fertilizers by increasing the yield of soft winter wheat grain is the largest - 6.10 and 6.39 kg/kg a.i. NPK, respectively.

“…Понимание механизмов, регулирующих массу зерна в стрессовых условиях, и наличие информации о потенциальных высокоадаптивных источниках поможет селекционерам повысить стабильность вновь создаваемых сортов по крупности зерна. Подчеркнем, что результатов, посвященных исследованию адаптивности образцов зерновых культур по отдельным элементам продуктивности, в частности по массе 1000 зерен, опубликовано сравнительно небольшое количество Goncharenko et al, 2020;Nikolaev et al, 2019;Serebrennikov, 2020;Tulyakova et al, 2021;Vahamidis et al, 2022).

Background. It is important and relevant to know whether the selection among cultivars for increased stability in the weight of 1000 grains involves a significant change in grain size. The aim of the study was to analyze the relationship between the 1000 grain weight in oat, barley and wheat accessions, on the one hand, and their adaptability indicators for this trait, on the other. Material and methods. The studied material included 10 cultivars of oat, 12 of barley, and 11 of wheat from the VIR collection. Plants were grown in 2021 at five different sites over Eastern Siberia (Krasnoyarsk Territory, and the Republic of Khakassia and Tyva). After harvesting, the weight of 1000 grains was measured for each cultivar. The coefficient of environmental variation (Cv), stress tolerance index (d), homeostasis parameter (Hom), stability level index (CSL), and breeding value index (Cs) were determined to assess the cultivars for the analyzed character. Results. Oat cultivars exhibited significantly lower plasticity and higher stability in their 1000 grain weight. The best adaptability characteristics were recorded for oat cvs. ‘Argument’ and ‘Kross’, barley cvs. ‘Krasnoyarsky 91’ and ‘Biom’, and wheat cvs. ‘Novosibirskaya 49’ and ‘Novosibirskaya 75’. Cvs. ‘Kross’ and ‘Argument’ (oat). and ‘Biom’ (barley) had the largest grain size and maximum values of the character’s stability parameters. Correlations of oat and wheat grain size with both plasticity indices were negative, and positive with all stability parameters, being significant for CSL and Cs. In the case of barley cultivars, the correlation between the weight of 1000 grains and the plasticity index was negative and statistically significant. Conclusion. The results demonstrate that when selecting oat, barley and wheat for increased stability of their 1000 grain weight, the grain size will not decrease. Moreover, it may have a tendency to increase.

Providing high and stable grain harvests with high content of valuable compounds in grain is an important task of crop production. The aim of the study was to assess the adaptability of oat accessions through the analysis of their chemical and physical properties and disclose relationships among adaptability indicators based on these characteristics.Eighteen oat accessions from the VIR collection, grown for 3 years in Eastern Siberia, were assessed. The content of β-glucans and oil, 1000 grain weight, and test weight were analyzed. Four adaptability indicators were measured for the aforesaid characters.Plasticity and stability parameters of the accessions showed no significant differences between the naked and hulled oat forms. Cvs. ‘Sapsan’ (k-15444) and ‘Aldan’ (k-15115) demonstrated the best adaptability in the content of β-glucans in grain, ‘Sayan’ (k-14043) and ‘Vyatsky’ (k-14960) in oil content, ‘Korifey’ (k-15113) and ‘Taidon’ (k-15183) in 1000 grain weight, and ‘Korifey’ and ‘Gosha’ (к-15120) in their test weight. Among the naked oat accessions, significant relationships were recorded between the adaptability indicators of the content of β-glucans or oil in grain and those of the test weight as well as between the average 1000 grain weight of the accessions and the parameters of their plasticity (negative correlations) or stability (positive correlations) for the said physical character.There is a high risk of obtaining hulled oats with reduced levels of oil in their grain, when selected for high stability for this character. It is assumed that successful oat breeding for increased adaptability in 1000 grain weight will be accompanied by an increase in grain size. The possibility of indirect estimation of the adaptability of naked oat accessions according to their β-glucan or oil content is shown on the basis of calculating their adaptability according to the test weight of their grain.
