The current paper has presented a material on agroecological estimation of the new soybean lines developed in the Agricultural Research Center “Donskoy”. As a result of the competitive variety testing in 2017–2019, five soybean lines of the middle-early ripening group were selected with a vegetation period less than 120 days, exceeding the standard variety “Don 21” in seed productivity. The temperature and water conditions during the years of study were different, which allowed evaluating the lines in contrasting cultivation conditions. Statistical data processing was carried out by B. A. Dospekhov’s analysis of variance (2012). Agroecological estimation of the new soybean lines was carried out according to S. A. Eberhart and W. A. Russell’s method (1984) and according to V. V. Khangildin’s method (1984). Based on the conducted study, there were identified the lines “L-1016” and “L-1017”, which are characterized by stabile productivity, and the lines “L-1001”, “L-1012” and “L-1013” which are responsive to the improvement of the agricultural background. The identified soybean lines “L-1016” and “L-1017” will be used in future breeding as the sources of adaptability, and the lines “L-1001”, “L-1012” and “L1013” to develop varieties of intensive type. Comparing the time cost, the need for computer technology to carry out calculations according to the methods of agroecological estimation proposed by S. A. Eberhart / W. A. Russell and V. V. Khangildin, the first method is more labor-intensive. According to the first method, the indicators of agroecological estimation must be recalculated if the number of samples changes, since they affect the final result of the calculations, but the second method does not need it. It has been recommended when working with a large number of breeding material to use the method proposed by V. V. Khangildin to speed up math calculations in agroecological estimation.

The purpose of the current study was to consider and identify promising peas lines with high grain productivity and determine their adaptability parameters. The field study was carried out at the FSBSI “Agricultural Research Center “Donskoy”, located in the southern part of the Rostov region during the 4-year competitive variety testing (2017–2020). The objects of the study were 19 breeding lines developed by the FSBSI “Agricultural Research Center “Donskoy”. All lines were of a leafless type. The standard variety was the variety ‘Aksaysky usaty 5’. The lines ‘G-1002’ (2.60 t/ha), ‘G-1003’ (2.81 t/ha), ‘G-1005’ (2.58 t/ha), ‘G-1007’ (2.56 t/ha), ‘G-1014’ (2.63 t / ha) and ‘B-3790/30-3’ (2.54 t/ha) showed a significant excess over the standard variety. The mean productivity in the competitive variety testing of 2017–2020 was 2.41 t/ha. The maximum productivity difference among the years was 1.63 t/ha, or 89% of the mean productivity. This indicates a high contrast of the cultivation conditions over the years. There have been identified the adaptability parameters of the pea lines (stress resistance, genetic flexibility, homeostaticity and breeding value), which exceeded grain productivity of the standard variety. The lines ‘G-1014’ (5.31), ‘G-1007’ (6.12), and ‘B-3790/30-3’ (6.47) showed the highest homeostaticity. The productivity of these lines was more even over the years and it is preferable to cultivate them in contrasting conditions (zones of risky farming, low agricultural background). The lines ‘G-1002’ (4.19), ‘G-1005’ (4.53) were a bit inferior to them. The line ‘G-1003’ had the lowest level of homeostaticity (3.98). The lines ‘G-1014’ (1.49), ‘G-1007’ (1.47), ‘B-3790/30-3’ (1.44) were characterized with the greatest indicator of breeding value. According to the results of the competitive variety testing in 2017–2019, in 2019 the line ‘G-1003’ with the highest grain productivity, was sent to the State Variety Testing under the name ‘Zernogradsky usaty’ in the North Caucasian (6) region. According to the estimation results of the adaptive properties, the variety is responsive to the improvement of cultivation conditions and has been recommended for cultivation in intensive technology.

The current paper has presented the study results on the ecological estimation of seed peas of different types of development. The purpose of our study was to assess the quantitative and qualitative indicators of seed peas varieties of different types of development in the southern part of the Rostov region. The trials were carried out on the experimental plots of the FSBSI “Agricultural Research Center “Donskoy” at the laboratory for legumes breeding and seed production. Autumn sowing was carried out in the second decade of October. Spring sowing was conducted in the third decade of March. The objects of the study were the variety ‘Legion’ sown in autumn and spring in comparison with the variety ‘Aksaysky Usatiy 5’, which was used as a standard variety in the trials. The statistical data were processed according to B. A. Dospekhov’s methodology (2012) using Excel with the STATISTICA 10 application. The variety ‘Legion’ sown in autumn ripened earlier in comparison with the standard variety ‘Aksaysky Usatiy 5’. Early ripening of winter peas than spring peas made it possible to evenly distribute the load on the harvesting equipment, since ripening of spring peas often coincided with ripening of winter grain crops, such as winter barley and winter wheat. The variety ‘Legion’ sown in winter exceeded the standard variety ‘Aksaysky Usatiy 5’ in such indicators as “plant height”, “number of beans”, “number of seeds”, “seed weight per plant” and “protein percentage”. The study results have shown that the conditions of the southern part of the Rostov region were favorable for the cultivation of winter peas. The winter peas ripened a decade earlier than spring peas, and seed productivity was 1.7–1.8 times larger.

To study the reaction of an early-ripening soybean variety to the formation of plant reproductive organs under the influence of different length of daylight hours, studies of 2 sowing periods in a growing house with a new early-ripening variety Sentyabrinka of the FSBSI FRC VNII of Soybean were conducted. Artificial reduction of the daylight duration to 8 hours was established from the phase of the 3rd triple leaf with alternating day and night periods in each variant 7 times during the growing season. The control was plants whose growth and development took place in natural light conditions. According to the research results, it was found that the change in the daylight duration during the vegetation period had a significant impact on the duration of the phases of plant growth and development, the growing season as a whole. When sowing soybeans on May 28 with a natural daylight, the height of plants and their seed productivity were higher than those of plants with a shortened daylight. At this sowing period, the highest productivity was obtained from one plant – 9.3 g, which is 1.0 g more compared to soybean plants with a sowing period of June 3. The growth of plants, the formation of reproductive organs and the seed productivity of the early-repining variety Sentyabrinka depended on the duration of daylight, which can be regulated by the sowing period.

Each region is characterized by a certain set of natural conditions. Therefore, it is necessary to have varieties of forage crops that can realize soil and climatic potential of the zone and are resistant to various possible stress factors. The purpose of the research is: study the variety samples of meadow clover according to the complex of economically useful characteristics in the competitive variety testing; identify the most promising ones in the conditions of the European North of the Russian Federation. The research was carried out in 2017, 2018 and 2019 at the experimental field of FSUE “Kotlasskoe”, which is located in the south-east of the Arkhangelsk region. Such breeding methods as selection, hybridization, creation of complex hybrid synthetic populations were used to create the studied variety samples. The studies were carried out according to the guidelines of the Federal Research Center “VNIIK named after V. R. Williams” and methodology of the State variety testing of agricultural crops (under the general editorship of Fedin M. A.). Soil of the experimental plots is weakly podzolic clay, medium cultivated on Permian clays. Mid-early diploid variety ‘Niva’ was used as a standard. The experiment was laid on a bare fallow; four-fold replication. Sowing was carried out with a SKS-6-10 seeder. Variety samples were evaluated according to a set of biological and agricultural characteristics: winter hardiness, vegetation period per mowing mass, plant height, leafiness, dry matter collection, protein content, protein collection, seed productivity. Agrometeorological conditions during the years of research were different, which allowed us to obtain more reliable results in assessing studied breeding material. All presented promising breeding samples exceeded the standard one in terms of the studied basic economic and biological characteristics. According to each studied indicator, we selected the best varieties. On average, over the years of research, a comprehensive assessment allowed us to identify the most valuable varieties that can form stable feed and increased seed productivity in northern conditions. They are K-2003, SD-289, K-1809, K-1556, ‘Taezhnik’. Winter hardiness of these samples varied from 84 to 94 %, dry matter collection – from 9.0 to 9.9 t/ha, seed yield – from 256 to 309 kg/ha, protein collection – from 1.26 to 1.35 t/ha. Variety ‘Taezhnik’ was included in the State Register of Breeding Achievements in 2020 for the 2nd region.

The current paper has presented the study results on the homeostaticity of the collection samples of soybeans according to the trait “seed weight per plant” in the southern part of the Rostov region, conducted on the fields of the FSBSI “Agricultural Research Center “Donskoy” in 2017-2019. The purpose of the research was to determine the homeostaticity of the collection samples of soybeans according to the trait “seed weight per plant”. The objects of the research were 75 samples of soybeans of the middle early ripening group, which varied according to their morphological, biological and economically valuable traits and properties. There have been selected 27 collection samples of soybeans, which significantly exceeded the standard variety in terms of to the trait “seed weight per plant”. The soybean variety ‘Don 21' developed in the FSBSI “Agricultural Research Center “Donskoy” was used as a standard variety. The meteorological conditions during the growing season of soybeans during the years of study were different, which made it possible to objectively estimate the parameters of homeostaticity. For statistical processing of the results obtained, there were used the Dospekhov's methods of analysis of variance, the homeostaticity indices (Hom) were calculated according to V. V. Khangildin. (1984). According to the study results, it was established that the sample ‘Veselovskaya 5', ‘Line 504/11' and ‘PR 110370 OZ 006' had high productivity indices per a plant, along with high homeostaticity indices. There has been recommended to use them in breeding for homeostaticity and ecological adaptability. The highly productive samples ‘Im 55-2', ‘Kyoto', ‘Kofu', ‘Line 696-1', ‘M-91-212006, ‘RZhT Shuna', ‘SVH 14 TOS 1D' have shown a low index of homeostaticity. They could be characterized as the samples responsive to the improvement of environmental conditions and could be recommended as an initial material when developing varieties of intensive type.

In 2016-2018 in the competitive variety testing there was conducted the study of peas on the fields of research crop rotation of the laboratory of legumes breeding and seed-growing of the FSBSI “ARC “Donskoy” located in the zone of unstable humidity of the Rostov region (Zernograd district). The analysis of the obtained seeds was carried out in the laboratory of biochemical estimation of breeding material and grain quality of the FSBSI “ARC “Donskoy”. The objects of research were new pea lines of breeding of the FSBSI “ARC “Donskoy”, which differed in their morphological, biological and economically valuable traits and properties. During the years of research, the meteorological conditions of the vegetation period of peas were contrasting, which made it possible to objectively estimate the lines in the climatic conditions. In the competitive variety testing for the period of 2016-2018, the evaluation of new promising pea lines due to their productivity and protein percentage resulted in identification the leafless pea lines “G-1002” and “G-1003” which exceeded the standard variety “Aksaisky Usaty 5” in productivity (0.30 and 0.39 t/ha) and protein yield (0.08 and 0.10 t/ha, respectively). There is a high correlation between seed productivity and protein content (0.95). There is a low correlation between protein percentage in seeds and protein yield (0.35). There is no correlation between productivity and protein percentage in seeds (0.03). The analysis of correlations shows that pea breeding on productivity directly affects on protein yield, i. e. the larger seed productivity, the larger protein percentage. The most productive pea lines are going to be used in further breeding work.

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.

The improvement of the breeding programs, selection of the optimal group of ripeness depends on the soil and climatic conditions for which varieties and hybrids are developed. One of the most important indicators of climatic conditions is the hydrothermal coefficient (HTC). The purpose of the current study was to analyze the effect of HTC on the productivity of maize hybrids of various groups of ripeness. The studies were carried out in 2014–2019 at the Agricultural Research Center “Donskoy” located in the southern zone of the Rostov Region, characterized by unstable moisture. The objects of the study were 96 interlinear maize hybrids of three groups of ripeness, namely an early ripening group (FAO 150), a middle-early ripening group (FAO 200) and a middle ripening group (FAO 300). There was a systematic use of variants in the trials. The weather conditions of the years 2014 and 2018 could be estimated as arid (HTC = 0.32–0.57). The years 2015, 2016, 2017 and 2019 were of medium aridity (HTC = 0.58–0.89). The HTC determined only for the entire vegetation period did not allow estimating objectively the growing conditions. There has been required a more detailed analysis of the HTC for the periods (months) of vegetation. On average, over the years of study, the middle ripening maize hybrids were characterized with the largest grain productivity (3.98 t/ha). The early ripening maize hybrids were characterized with the smallest productivity (3.31 t/ha). The middle-early ripening hybrids were characterized with the average value (3.80 t/ha). However, in different years, the maximum grain yields were produced by the hybrids of various groups of ripeness, including by the early ripening varieties, that depended on the amount of HTC in different vegetation periods. There have been identified average positive correlation coefficients between the HTC values and maize hybrids’ productivity (r = 0.64–0.74). The use of maize hybrids of various groups of ripeness can stabilize the gross harvest of maize.

The studies were carried out in 2015–2017 at the FSBSI “Agricultural Research Center “Donskoy” in order to determine the opti­mal values of quantitative traits, the combination of which allows forming the maximum yield for hybrids of grain use in arid conditions. The 96 maize hybrids were the initial material which were studied for grain productivity, plant height, height of ear attachment, length of the vegetation period and of the period from germination to ear flowering. The presence, strength and direction of correlation between grain productivity and quantitative characteristics have been established. There has been identified a weak positive correlation between the grain productivity and plant height (r = + 0.10…+0.23). Maize hybrids for grain use should be of medium height with an optimal value of the trait of 220–250 cm. The grain productivity had an average in 2016 (r = + 0.49) and a weak in 2015 and 2016 (r = + 0.05; r = +0.17) dependence on an ear attachment height. The optimal values of the trait were 80–95 cm. The nature of the dependence between grain productivity and the length of the vegetation period greatly differed through the year of study. In 2016 an average positive correlation was r = + 0.52; in 2015 and 2017 there was a weak negative correlation r = –0.14, r = –0.24. Through different years, the hybrids of various groups of ripeness formed the maximum grain productivity of 5.0–5.5 t/ha. The hybrids of the middle-early group of ripening, as well as the early-ripening and middle-ripening hybrids had an advantage before the middle-early group slightly differing in the length of the vegetation period. The optimum length of the vegetation period is 97–110 days, the period from germination to ear flowering is 53–61 days.

The current paper has presented the results of breeding work on maize in the Agricultural Research Center “Donskoy”. The three-line and double interlinear middle early and middle ripening maize hybrids of various economic use ‘Zernogradsky 242 MV’, ‘Zernogradsky 282 MV’, ‘Zernogradsky 288 MV’, ‘Zernogradsky 299 MV’, ‘Zernogradsky 354 MV’, ‘Zernogradsky MV’, ‘Stepnyak MV’ were developed and included into the State List of Breeding Achievements from 2006 to 2020. The Competitive Variety Testing has identified a new high-heterosis simple hybrid ‘Zernogradsky 352 MB’ and the new early ripening hybrids ‘Krucha M × KB 215’, ‘Krucha M × SP 56/57’ with low harvesting grain moisture. The main method used to develop maize hybrids was an interline hybridization using heterosis in the first generation (F1 ). There have been determined the priority directions of further breeding, namely early ripeness, grain humidity-transfer intensity during ripening, drought resistance, high starch content in grain. There has been developed new initial material for each direction of breeding. There have been selected the introduced testers (‘Alpha M’, ‘Almaz M’, ‘Aurora S’, ‘Milena M’, ‘Istok S’) to develop early-ripening hybrids. There have been identified the early and middle-early ripening self-pollinated lines ‘C 207’, ‘RD 12’, ‘TVA 308’, ‘PLS 61’, ‘KB 215’, etc., with a high grain humidity-transfer intensity during ripening (0.95–1.30% per day), low harvest moisture content of grain (10.8–13.8%). There have been developed the new self-pollinated waxy maize lines (24/29/5, 25/64/10, 26/8, 26/4, 26/80, 24/28) with 68.1–69.8% of amylopectin starch in grain. There have been identified the new self-pollinated maize lines resistant to water stress (DS 498/217-3, DS 257/85-5, DS 498/203, KB 262, etc.) promising for breeding drought-resistant maize hybrids.
