The yield potential of winter wheat (Triticum aestivum L.) is formed in changing weather conditions and depends on the proposed agro-technological measures, to which the response of a particular variety is different. The purpose of this study was to determine the influence of weather factors on the field germination of soft winter wheat seeds, the growth and development of plants in the autumn and wintering in the zone of the Western Forest-Steppe of Ukraine, by sowing high-quality basic seed, careful soil preparation and the presence of optimum environmental factors. A sufficient level of productive soil moisture, which protects young shoots from possible deficiency after germination and is a long-term source of moisture at the next stages of organogenesis, has a great influence on obtaining friendly and timely shoots. Often overwintering conditions, when plants suffer from low negative temperatures at the beginning and at the end of the winter period, ground ice crust, resumption of vegetation in winter are the causes of freezing, loss, and ultimately a decrease in yield and seed quality. It has been confirmed that an increase in the temperature regime in 244-247°C in the autumn-winter period and the optimal amount of precipitation contribute to sufficient (31.6-34.6 mm) productive soil moisture (0-20 cm), which positively influences the process of germination of soft winter wheat, provides a high percentage of field germination of seeds of varieties (93.8-94.5%), lengthens the autumn development of plants by 3-12 days, which causes 3.5-5.7% higher accumulation of sugar content in the tillering nodes and a high percentage of overwintering (up to 95.5-96.4%). Varieties of the forest-steppe ecological type of soft winter wheat have insignificant phenotypic variability of adaptive traits, therefore, in the production of grain and seed products, it is recommended to give preference to the plant varieties listed in the Register, suitable for distribution in Ukraine for the Forest-Steppe zone, Polissya. The recommendations set out in this scientific work will help agricultural producers of the studied soil and climatic zone to carry out an effective, more ecologically plastic, highly productive variety replacement

Numerous studies have quantified the developmental responses of wheat to vernalization, but its response compared to a weedy relative, jointed goatgrass, remains relatively unknown. Six paired jointed goatgrass collections gathered from Washington and Oregon fields, and winter and spring wheat, were grown in field studies to quantify yield and germination in response to vernalization. Monthly planting dates initiated in October and concluded in March were used to vary the vernalization durations for plants sown at three Oregon locations (Corvallis, Moro, and Pendleton) over two growing seasons. Minimum vernalization requirements to produce reproductive spikes were similar among plants of six jointed goatgrass collections. Jointed goatgrass collections grown at Corvallis required a minimum of 89 and 78 vernalization days (January 17, 2003 and January 22, 2004 sowing, respectively) to produce reproductive spikes, and plants grown at Moro required 60 vernalization days (March 3 and February 23) in both years, and 48 and 44 vernalization days (March 3 and February 24) were required by plants to produce spikes at Pendleton. Jointed goatgrass spikelet and winter wheat seed yield were positively influenced by vernalization days, experiment location, and year. The strength of the interactions among these main effects differed among jointed goatgrass collections and winter wheat. The effects of vernalization on jointed goatgrass yields and seed quality were more pronounced at Pendleton, OR, a location where jointed goatgrass has adapted, compared to Corvallis, OR, where it has not adapted. The minimum vernalization days required to produce germinable seed differed among jointed goatgrass collections, winter and spring wheat. There was not a selection of spring-adapted jointed goatgrass populations in the populations tested. Yet if spring temperatures are cool, minimum conditions for vernalization may be satisfied, and the benefits of planting spring crops to control jointed goatgrass would be reduced.

Purpose and objectives. To evaluate the effect of sorting seeds by size on their quality indicators: germination energy, laboratory germinability and 1000-grain weight. Materials and methods. The experiments were carried out in the experimental field of the Plant Production Institute named after V.Ya. Yuriev of NAAS in accordance with the field experimentation method in 2016–2018; 26 winter bread wheat lines and varieties were studied. The varieties and lines were grown in variety trial experiments; the plot area was 10 m2. Seeds were separated on sieves of a laboratory separator RLU-3; the 1000-grain weight was measured; the laboratory germinability and germination energy were determined. Results and discussion. When winter bread wheat seeds are sorted on sieves, they are separated into fractions with various 1000-grain weights. The separated fractions of winter wheat seeds have different sowing qualities. The 2.5 x 20 mm seeds and 2.8 x 20 mm seeds are of the best quality (germination energy, germinability). It was found that in 2016–2018, the germination energy, laboratory germinability and 1000-gain weight changed depending on the growing conditions. They were the highest in 2017. The varieties with a high 1000-grain weight have been identified: Doskonala, Pryvablyva, Smuhlianka, and Haiok. The highest germination energy and germinability were intrinsic to varieties Yednist, Harmonika and Bunchuk. Yednist (93.3%), Harmonika (94.3%), Metelytsia Kharkivska (94.5%), Bunchuk (94.7%), Alians (93.3%), Podolianka (92.5%), Patriotka (93.6%), Zapashna (93.3%), Dyvo (93.7%), Doskonala (93.6%), Krasa Laniv (94.0%), Smuhlianka (93.1%), and Erythrospermum 408-13 (93.7%) had a high germinability of small seeds (2.2 x 20 mm). To clean these varieties, especially in years with low seed yields, it is recommended to use seeds of the standard size (2.2–2.5 x 20 mm). Conclusions. The relationships between the grain size and sowing qualities of seeds have been established. Separation of seeds is an effective technological method allowing for selection of top-quality seeds

Improving the quality of wheat grain is an important task of agricultural production. In recent years, the production of strong and valuable wheat, necessary for the production of high-quality baking flour, has decreased. In this regard, the study of the quality of grain varieties of winter wheat in specific soil and climatic conditions of the Rostov region is becoming topical. Therefore, the purpose of our research was to study the main indicators of grain quality of varieties of soft winter wheat (protein and gluten content, flour strength, bread size from 100 g of flour) in ecological variety trials to select the best under conditions of the Rostov region. The studies were carried out on the trial fields of the Laboratory of selection and seed production of winter soft wheat of intensive type of the State Scientific Establishment “Agricultural research center «Donskoy»” (Rostov region) in 2014–2016. Seventy-five varieties were studied in the course of the research. Planting dates – optimal for implementation of agricultural and agro-technical measures. Planter – «Wintersteiger Plotseed S.» Seed placement depth – 4–6 cm. Preceding crop – black fallow. Accounting square of fields – 10 m2, double replication. Seeding rate – 4.5 million seeds per hectare. Grain quality was assessed according to the methods of the national standards of the Russian Federation. Such grain quality indicators as gluten content (according to GOST R 54478-2011), protein mass fraction (as required by GOST 108460-91), baking properties of flour (in a laboratory using the remix method) were determined. The article discusses the main indicators of the quality of grain and flour of winter soft wheat varieties in ecological variety testing and compares them. Analysis of the main indicators of the quality of varieties in trials showed that in the south of the Rostov region in 2014–2016 flour strength and gluten content were the most variable indicators. In terms of protein content (> 14.5 %), 8.0 % of the studied varieties were in full compliance with strong wheat standards; by the gluten content (> 28 %) – 7.0 %; by the flour strength (>280 e.a.) – 9.0 %. Five varieties of winter soft wheat: ‘Aksinya’, ‘Tanais’, ‘Asket’, ‘Nakhodka’, ‘Yumpa’ (Russia) with a complex of economically valuable traits are of greater interest for practical breeding in terms of improving grain quality.

The authors present the results of many years research on the study of the growth regulators “ХЭФ ВР” and Stabilan BP influence on the yield and quality of winter wheat of new varieties – Alekseich and Adel, selected by the National Center of Grain named after P. P. Lukyanenko in the steppe zone of the Mozdok region, Republic of North Ossetia – Alania. The aim of our research was to improve the tech nology of winter wheat cultivation using the new generation plant growth regulators “ХЭФК”, which stimulates the growth and volume of the root system, strengthens the stem by reducing the length of internodes and increasing the diameter of the stem, prevents lodging of crops, and has a positive effect on yield and quality. Stabilan slows down the growth of stem cells in length, which leads to a decrease in plant height and thickening of the spike, providing an increase in yield and grain quality. To achieve this goal, the research tasks included studying the effect of plant growth regulators on the growth processes of winter wheat at the initial stages of ontogenesis, on the yield and quality indicators of winter wheat grains of the Alekseich and Adel varieties in the steppe zone of the Mozdok region of the Republic of North Ossetia – Alania. Our studies have shown that growth regulators had a positive effect on the processing of seed material and sowing of winter wheat varieties Alekseich and Adel. The grain yield is increasing; the increase in relation to control was up to – 1.36 t/ha. The growth regulators “ХЭФК” and Stabilan were studied; they had a positive effect on the quality indicators of winter wheat grain, on the protein content, and the weight of 1000 grains. The highest yield was obtained on the variant with the use of the growth regulator “ХЭФК” – 4.63 t/ha.
