The research was carried out in 2005 – 2019 at the Federal Rostov Agrarian Research Center in the Rostov region. The material was the breeding material of various generations of the breeding center. The introduction of semi-dwarf forms into the selection process was accompanied by the involvement of medium-sized local varieties Tarasovskaya 29, Severodonskaya, Severodonskaya 5, Severodonskaya 12, which were adapted to local conditions as step crosses. Also recursive parental forms from various ekonish were used. Field experiments and censuses were carried out in accordance with the methodology of the State Commission for Variety Testing (1971, 1989) and the Methodological Instructions of the World Collection Vir (1977). Breeding of winter wheat was carried out by conventional methods using the bulk method and pedigree.The material was the selection material of different generations of FRANZ breeding. Recombinants of previous generations were used to create varieties of winter soft wheat of the new morphobiotype Donmira, Acapella, Bylina Don.  Under different stress factors, the features of the formation of agrocenoses of new phenotypes were revealed. In order to improve individual characteristics, sources of winter and frost resistance were used.  A marker sign of selection for productivity and adaptability in drought conditions is an increase in the weight of grain from the plant and ear, the yield index. Further development of breeding of semi-dwarf varieties will be associated with an increase in the capacity of the agrocenosis. The research was implemented in the creation of 20 varieties of winter soft wheat, which are included in the State register of breeding achievements, with a wide area of cultivation.

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.

Winter Wheat Varieties

To successfully increase grain production and improve its quality, the development and introduction of new winter wheat varieties is of great importance. The winter soft wheat varieties developed by the FSBSI “Agricultural Research Center “Donskoy” and included into the State List of Breeding Achievements of the Russian Federation are able to form grain with 30.0% gluten and more, and are suitable for the first, second and third class of baking. A comparative characteristic of the grain quality of winter wheat varieties of the intensive type included in the State List and their ability to form food grain suitable for baking is currently of practical interest. There have been studied 6 varieties in the conditions of drought in 2013 and 2014 (the amount of precipitation during the growing season was 190.0–191.5 mm, the average daily air temperature was 20.3–20.9 °C), and in the conditions of excess moisture in 2016, 2017 (the amount of precipitation was 274.2–292.8 mm, the average daily air temperature was 19.5–20.4 °C). The studied varieties formed the highest productivity from 8.70 to 9.01 t/ha under conditions of excessive moisture. Under drought conditions, productivity of the varieties decreased significantly and ranged from 6.50 to 7.69 t/ha. Better grain quality of the studied varieties was formed in the conditions of the drought of 2013, 2014 with 14.9 to 15.9% of protein and 27.9 to 31.0% of gluten. Food grain close to the first class (from 30.0 to 31.0% of gluten) were formed by the varieties “Aksiniya”, “Tanais” and “Nakhodka”; the second class (more than 28.0% of gluten) was obtained from the varieties “Shef” and “Etuyd”. The ranking method according to grain quality indicators allowed establishing an average rank and identifying the varieties “Aksiniya”, “Tanais”, “Nakhodka” and “Shef” with the best baking traits.

Creation and introduction into production new high-yielding and early ripening varieties of soft winter wheat adapted to certain weather conditions are the principal ways to increase yield and improve general harvest volumes. A properly selected variety is one of the most effective ways of achieving crop yield improvement for any farm. To realize the potential for increasing yields, it is crucial to bear in mind specific soil and climatic conditions. The aim of the research was to characterize a new variety of winter soft wheat ‘Podarok Krymu’ by economic and biological qualities, as well as morphological characteristics. Soil of the experimental plot – chernozems ordinary with a thick humus layer (up to 140 cm). The meteorological conditions during the years of research were quite diverse, which made it possible to evaluate the new variety by a set of economically valuable features. The studies were carried out in 2015–2019 on the experimental fields of the scientific crop rotation of the Department of Winter Wheat of State Scientific Establishment “Agricultural research center “Donskoy” (SSE “ARC “Donskoy”). The object of the research – a new variety of winter soft wheat ‘Podarok Krymu’. Winter soft wheat variety ‘Don 107’ was used as a standard. Preceding crop – corn for grain. The accounting area of the variety test plot – 10 m². Field experiments were replicated six times. In 2019, variety ‘Podarok Krymu’ was submitted for State Variety Testing by SSE “ARC “Donskoy” together with the Research Institute of Agriculture of Crimea. This variety has a high potential for grain productivity. The average yield in the competitive variety testing was 7.71 t/ha (preceding crop – corn for grain), which is 0.39 t/ha higher than the average yield of standard variety ‘Don 107’. According to the length of the growing season, the variety belongs to the early maturing group; its ears emerge and kernels ripe three days earlier than that of the standard. The high and stable yield of the new variety is ensured by its tolerance to drought and heat, increased winter hardiness and resistance of plants to frost, as well as resistance to the main diseases typical in the regions where studies are being conducted. Since the autumn of 2020, ‘Podarok Krymu’ has been studied to cultivate it in the North Caucasian, Lower Volga and Central Black Earth regions of the Russian Federation.

Winter Bread Wheat

The systematic study on winter wheat breeding began in 1955 in the former Zernograd experimental station, and now the Federal State Budgetary Scientific Institution “ARC “Donskoy”. Under these conditions, the development of the most suitable for local conditions varieties of intensive type with increased frost resistance determined the main direction of winter wheat breeding in those years. In the early 1980s, the area of black fallow increased in the Rostov region, much attention was paid to irrigated agriculture. There was planned to increase the area under irrigation in the North Caucasus to 1 million hectares. Therefore, there was set a goal to develop highly productive, low-stemmed, resistant to lodging varieties, responsive to mineral fertilizing with complex immunity to diseases. The breeding work of the laboratory for the breeding and seed production of winter bread wheat of an intensive type over the past forty years resulted in the development of 22 varieties of intensive type with good adaptability to the conditions of the Rostov region. In 2020, 17 winter bread wheat varieties of an intensive type were included into the State List of Breeding Achievements, five varieties ‘Yubiley Dona’, ‘Zodiak’, ‘Univer’, ‘Razdolye’, ‘Rubin Dona’ are currently undergoing the State Variety Testing at the SVTs of the Russian Federation. A stable productivity improvement is possible only with the emphasis on the development of varieties with broad adaptive properties, providing sufficiently high yields under various cultivation conditions. Among the breeding traits that affect productivity stability, the most significant in the conditions of the Don are winter and frost resistance, disease resistance, drought resistance, early ripeness, and grain quality. Therefore, the adaptive potential increase is the most important task for the future breeding. In order to solve this problem, intraspecific and interspecific hybridization, followed by targeted selection, remains the main breeding method of winter bread wheat of an intensive type.

In winter wheat crops, the fight against weeds, together with the use of mineral fertilizers, which increase the yield and quality of the crop by reducing the removal of nutrients from the soil, is an urgent production task. The purpose of the research is to develop methods for increasing the yield of winter wheat with the combined use of herbicides and mineral fertilizers. Field experiments were carried out in the steppe zone of the Republic of North Ossetia – Alania in 2017–2019. The soil of the plot is chestnut calcareous. Weather conditions during the years of the research were favorable. The object of research is the high-yielding winter wheat variety Utrish. Mineral fertilizers stimulate the vital activity of soil microorganisms and enhance the cycle of biological transformation of plant nutrients, and herbicides have an inhibitory effect on cellulose-decomposing microorganisms, which ultimately reduces the rate of cellulose decomposition. Cellulose decomposed most intensively on backgrounds where mineral fertilizers were used. In control variant 3, the determination period, cellulose decomposed by 29.8%, against an average background (N60P60K60) by 40.2%, and against an increased background (N90P90K90) – 43.6%. Herbicide Grench at a dose of 10 g/ha on backgrounds without fertilizers and with fertilizers in different doses ensured the death of weeds during the growing season by 76.6 ... 89.2%. The herbicide Luvaram (1.6 l/ha) also provided high weed death – 56.4–62.6%. The application of a tank mixture (Grench 5 g/ha + Luvaram 0.8 l/ha) reduced weed infestation of winter wheat crops by 85.3–89.2% on different backgrounds of fertilization. The highest yield and profitability in the experiment were noted in the variant of the combined use of mineral fertilizers and herbicides. The level of profitability against the background of medium doses of mineral fertilizers (N60P60K60) was 130–150%, and against an increased background (N90P90K90) – 149–169%.

The results of studying the influence of elements of the technology of cultivation of spring wheat (various predecessors, methods of basic tillage, doses of mineral fertilizers) in order to obtain grain that meet the food requirements (GOST 9353-2016) are presented. The studies were carried out in 2015–2017 in the Ulyanovsk region in the forest-steppe zone on leached chernozem. The object was the Ulyanovskaya 105 spring soft wheat variety, which has been recommended for cultivation in the Volgo-Vyatka (4), Middle Volga (7), Ural (9) regions of the Russian Federation since 2017. The scheme of the experiment provided for placement after peas and winter wheat, autumn main dumping and shallow tillage. In each of the options, the sowing was carried out using three backgrounds of mineral fertilizer – N24Р6 К0 kg/ha a.i. before sowing; N64Р18К35 kg/ha d.v. before sowing + retardant “Tse Tse Tse 750” (chlormequat chloride); N50Р30К70 kg/ha d.v. before sowing + N25 in tillering + N30 after heading + retardant “Tse Tse Tse 750”, calculated for the planned yield of 4.0; 5.0 and 6.0 t/ha, respectively. The meteorological conditions in the years of research were characterized by uneven precipitation (HTC in 2015 – 0.7; in 2016 – 0.8; in 2017 – 1.4). The grain yield of the studied variety of spring soft wheat on average for the variants of the experiment ranged from 3.82 t/ha to 5.60 t/ha with its high quality. The largest amount of protein (720–760 kg/ha) and grain weight per ear (1.07–1.08 g) were formed by the predecessor of peas after plowing against the background of the introduction of mineral fertilizers in doses calculated for the planned yield of 5.0–6,0 t/ha. In terms of the content of crude gluten (28.1–30.9%), in nature (786–798) and vitreousness (87–91%), the grain corresponded to the indicators of class 2, in terms of protein content in the grain (12.5–13.5%) – indicators of the 3rd class of GOST 9353-2016. Higher quality grain with a higher yield level was formed according to the pea predecessor. The coefficient of elasticity of flour dough within the normal range for strong wheat (0.70–0.85) was observed on all variants of plowing and on 1 background of mineral fertilizers for fine processing according to the predecessor winter wheat, as well as on 1 and 2 backgrounds of mineral fertilizers according to to both methods of basic tillage according to the pea precursor. According to the general baking assessment (4.1–4.4 points), the Ulyanovskaya 105 variety corresponded to the norm for valuable crop varieties.
