The relevance of the current study is due to the fact that global warming in the south of Russia has significantly moved forward the onset of the hot period, especially in areas of risky farming. Sowing at the previously recommended scientifically based optimal time no longer guarantees stable yields of maize. Based on this, the purpose of the study was to determine the effect of the sowing time of new promising maize hybrids of our own breeding on productivity and yield structure elements in the steppe part of Kabardino-Balkaria. The study was carried out in field trials on the field of the research and production site of the Institute of Agriculture of the KBRC of the Russian Academy of Sciences in 2019–2021. In general, during the years of study, weather conditions were typical for the steppe area of the KBR. As a result, there was determined that the optimal sowing time for maize hybrids was the second decade of April. When sowing at this time, there was identified productivity improvement and an increase in the values of yield elements. On the contrary, sowing in the third decade has shown a decrease in the values of these indicators in all studied samples. During the second sowing period, there was the greatest productivity decrease among the late-maturing hybrids ‘Karat SV’, ‘Terek’ and the hybrid population ‘Kabardinskaya 3812’ by 1.4; 1.5 and 1.8 t/ha, respectively. The middle-early hybrid ‘Maisky 260 MV’ has shown a smaller decrease by 0.7 t/ha. During the first sowing period, number of ears per 100 plants increased by 4–11 pieces. The ears were better grained with 5–60 pieces of the excess over the second period. The weight of one cob during the first sowing period ranged 105–120 g on average, which was 9–22 g more than the same indicator during the second sowing period.

In the last decade there has been established an increase in the prevalence of Puccinia helianthi in sunflower crops in Russia. In the Rostov region, on the territory of the Don Experimental Station (the Azov region), severe damage by the sunflower rust pathogen was established in 2020. In this regard, there was a need to study the race of the fungus on sunflower crops in the Rostov region. The purpose of the study was to identify rust pathogen isolates collected from sunflower crops in accordance with the accepted international triplet nomenclature in different areas of the Rostov region in the period 2021–2023. As testers, there was used a set of differentiating lines of sunflower resistance to the pathogen, containing SM 90, SM 29, P-386, HA-R1, HA-R2, HA-R3, HA-R4, HA-R5 and the line ‘ED 47’, susceptible to all biotypes of the fungus. The total sample consisted of 237 parasite urediniospore isolates collected from infected leaves of sunflower plants. There were differentiated 34 biotypes of P. helianthi. The most virulent pathotype 777 was identified among isolates from the Tatsinsky, Morozovsky and Konstantinovsky districts of the region in 2023. The race with code number 700 was identified in almost all represented areas of the region and accounted for 52.7% of the studied sample of sunflower rust pathogen isolates. In the current work the racial composition of the pathogen in the Rostov region was studied for the first time. The study results have indicated the need to continue monitoring new biotypes of P. helianthi, as well as expand and accelerate work on the development of sunflower hybrids resistant to the predominant race with code 700 in the sample.

The purpose of the current study was a bioenergy estimation of different seed sowing rates of spring barley and oat varieties in the conditions of the Krasnoyarsk forest-steppe. The trials were carried out in the village of Minino, Emelyanovsky district, Krasnoyarsky Krai in 2021–2023. The objects of the study were the spring barley varieties ‘Abalak’, ‘Takmak’, ‘Oplot’, ‘Biom’ and the spring oat varieties ‘Tubinsky’, ‘Sayan’, ‘Kazyr’, ‘Uspekh’. Experimental schemes were as follows: barley varieties with seeding rates of 3.5, 4.0, 4.5 million germ. grains per hectare; oat varieties with seeding rates of 4.0, 4.5, 5.0 million germ. grains per hectare. High yields (5.60–5.71 t/ha) were produced by the barley varieties ‘Oplot’ and ‘Takmak’, while other varieties produced less on 0.9–1.4 t/ha. There has been revealed that the reproduction coefficient of barley seeds increased to 34.6 at a seed-sowing rate of 3.5 million germ. grains per hectare and decreased to 22.2–31.3 at a seed-sowing rate of 4.5 million germ. grains per hectare. There has been established that among oats, the variety ‘Tubinsky’ produced the highest yield of 4.79 t/ha at a seeding rate of 5.0 million germ. grains per hectare, followed by the variety ‘Sayan’ with 4.85 t/ha, the new promising variety ‘Uspekh’ with 4.67 t/ha and ‘Kazyr’ with 4.53 t/ha. The reproduction coefficient reached 26.9–29.7 with 4.0 million germ. grains per hectare and 21.3–23.5 at 5.0 million germ. grains per hectare. The energy estimation has shown that the optimal seed-sowing rate is 4.5 million germ. grains per hectare for barley varieties and 4.0 million germ. grains per hectare for oat varieties. The total energy increase (the difference between the total energy and energy costs) was 94.4 and 83.2 GJ/ha for the barley varieties ‘Takmak’ and ‘Oplot’, respectively and 58.9 and 59.0 GJ/ha for the oat varieties ‘Tubinsky’ and ‘Sayan’.

Rice is an important food product for people. Milled white rice is mainly used or food purposes, but unpolished rice is also used. The cells of the aleurone layer and the embryo of the rice grain contain lipids, the presence of which strengthens the immune system and protects against heart disease and cancer, which has increased interest in them. The current paper has provided a review of the information on the study of quantitative trait loci connected with lipid content in rice grain. The study was conducted in China, Korea, and Japan from 1983 to 2021 using dihaploid lines from hybrids among rice varieties with contrasting lipid content. There was identified a correlation with QTL on 12 rice chromosomes with the help of a microsatellite marker map. Hu et al. (2004) found three QTLs for oil content located on chromosomes 1, 2, and 5. Yu et al. (2009) found four QTLs on chromosomes 3, 5, 6, and 8. Qin et al. (2010) mapped eight QTLs to chromosomes 1, 2, 3, 5, 6, 7 and 9. Kim et al. (2013) found a significant QTL, qRLC5, on chromosome 5. Yun et al. (2014) found that high lipid content was determined by three QTL on chromosomes 2, 3 and 6. Ying et al. (2012) identified 29 QTL on 10 chromosomes, several for seven fatty acids. Zhou and his colleagues (2021) conducted a genomic study of oil composition and concentration in different groups of 533 cultivated rice varieties and identified 99 QTL, 94 of which were associated with oil composition and five of them with oil concentration. These QTLs will allow developing pyramids of favorable alleles to improve rice quality using marker-assisted breeding.

The purpose of the current study was to identify the effect of various crop rotations and rates of application of mineral fertilizers on productivity of winter wheat and spring barley, the productivity of crop rotations and the economic efficiency of cultivating crops. The study was carried out in a stationary field trial of the FSBSI “Kursk FARC” on typical heavy loamy blackearth (chernozem) in 2015–2023. Agricultural crops were grown in three crop rotations: 1 – grainrow fallow (black fallow, winter wheat, sugar beets, maize for silage, barley); 2 – grain-row green manure fallow (green manure fallow, winter wheat, sugar beets, maize for silage, barley); 3 – crop rotation (horse-bean for grain, winter wheat, sugar beets, white lupine for grain, barley). During the trial there have been compared two contrasting levels of mineral fertilizer application N30Р30К30 and N52Р52К52 per hectare of crop rotation area. The non-marketable portion of the harvest of all crops was used as fertilizer. Agricultural technology was generally conventional for the area. There has been established that, under all weather conditions, the highest yield of winter wheat at a low background of fertilization (N30Р30К300 per hectare of crop rotation area) is produced in green manure fallow, and at a high background of fertilization (N52Р52К52 per hectare of crop rotation area) in black fallow. There was found that the most favorable conditions for cultivating barley were created when cultivating with white lupine for grain. Fertilization increase led to productivity increase of the grain crops, but, at the same time, to a production profitability decrease. There has been determined that productivity of crop rotations with fallow forecrops is 14 % higher compared to crop rotations with a legume forecrop (horse-bean for grain). According to calculations, on average over the years of study, the most profitable was the winter wheat cultivation in black fallow, and spring barley cultivation in white lupine for grain. At the same time, the indicator of production profitability level decreased with an increase in the rate of mineral fertilizing, which results in production costs’ increase.

Spring vetch is a valuable leguminous plant that serves as a source of high-protein feed for farm animals, and due to its ability to fix nitrogen, it is a good green manure. The cultivation of this crop plays an important role in solving the problem of plant protein deficiency; however, in the Cis-Ural steppe of the Republic of Bashkortostan, productivity of vetch seeds and green mass is low and unstable over the years. In this regard, the purpose of the current study was to estimate the potential productivity of spring vetch varieties that would be promising for cultivation in the soil and climatic conditions of our region. Field trials were conducted in 2021–2023. Weather conditions during the years of study were contrasting in temperature and moisture availability. The material for the study was a set of spring vetch varieties ‘Omichka 3’, ‘Orlovskaya 91’, ‘Lugovskaya 98’, ‘Lgovskaya 22’, ‘Yubileinaya 110’, ‘Uzunovskaya 8’, ‘Valentina’, recommended for cultivation in the Ural region of the Russian Federation. The estimation, records and measurements were carried out in accordance with the Methodological recommendations for the study of the grain legumes’ collection (1975) and the Methodology for the State Variety Testing of Agricultural Crops (2019). As a result, there has been found that in the conditions of the Republic of Bashkortostan the spring vetch varieties ‘Lgovskaya 22’, ‘Omichka 3’, ‘Uzunovskaya 8’ with a vegetation period length of 74.3±11.6 – 75.7±12.1 days turned out to be the most earlymaturing. According to the indicators of the main yield structure elements, the varieties ‘Valentina’, ‘Uzunovskaya 8’, ‘Yubileinaya 110’ were the best in terms of ‘number of beans per plant’ (4.4±0.7 – 4.9±1.3 pcs.), ‘seeds per plant’ (18.1± 5.9 – 18.5±6.8 pcs.), ‘seed productivity’ (0.90±0.26 – 0.96±0.27g). According to our study, the most promising varieties for production in the Republic of Bashkortostan are ‘Uzunovskaya 8’ and ‘Valentina’, which were the best ones in terms of productivity of grain (1.25–1.29 t/ha), green mass (6.40–6.53 t/ha) and hay (1.61–1.65 t/ha) in 2021–2023.

The current paper has presented the results of an analysis of promising winter barley lines and varieties developed by the FSBSI “Agricultural Research Center “Donskoy” to select valuable genotypes for breeding programs. The basis for the analysis of the studied samples was the methodology for a comprehensive estimation of breeding results, developed by the researchers from the FSBSI “ARC “Donskoy” and the FSBEI HE DSTU. The study was conducted at the FSBSI “Agricultural Research Center “Donskoy” in 2021–2023. Sowing was carried out in 6-fold repetition, the local variety ‘Timofey’ was taken as a standard. There have been analyzed 14 economically valuable traits, identified as the most significant according to the methodology for a comprehensive estimation of barley breeding identifiers. The purpose of the current study was to conduct a comparative estimation of breeding winter barley lines according to the most significant traits for the selection of promising samples. The studied varieties and lines were ranked according to a set of traits and properties into three groups, such as promising, not very promising, and unpromising. The promising group included the new varieties ‘Step’ and ‘Alabai’, sent to the State study in 2, 5, 6 and 8 regions of the Russian Federation in 2022 and 2023, respectively, as well as the lines ‘Parallelum 2015’, ‘Parallelum 2136’, ‘Pallidum 2100’ and ‘Bezosty 2074’, characterized by high indicators of a complex of basic economically valuable characteristics and properties. These samples are being planned to send to the State Commission of the Russian Federation for Testing and Protection of Breeding Achievements.

The current paper has presented the study conducted in the alfalfa collection nursery on the experimental plots of the Agricultural Research Center “Donskoy” in the period from 2021 to 2023. The purpose of the study was to determine the dependence of green mass productivity of collection alfalfa samples on the morphological traits of plants. The object of the study was a collection of alfalfa, consisting of 105 samples developed created at FSBSI ARC “Donskoy”. Sowing was carried out manually, with row spacing of 20 cm. The area of the plots was 1 m2 , with double repetition. The seed-sowing rate for alfalfa was 2 g/m2 . The standard variety was ‘Rostovskaya 90’. As a result, there was revealed that over 3 years the highest mean productivity of alfalfa green mass was formed in two groups of samples according to plant height: 1) 80–85 cm – 8.10 kg/m2 (the samples ‘SGP-424’, ‘SPCh 401/2000’); 2) 105–110 cm – 7.88 kg/m2 (‘SGP-162’, ‘SGP-189’, ‘SGP-175’, etc.). This indicator of alfalfa productivity was the highest (7.81 kg/m2 ) in the optimal values of tillering (15–20 pcs.). The highest alfalfa green mass productivity was formed by the samples with foliage of 48–50 % and 42–44 %. The green mass productivity of alfalfa samples varied within the range of 3.33–10.49 kg/m2 . There have been identified 7 samples which productivity ranged from 9.09 kg/m2 to 10.49 kg/m2. There have been selected the samples that combined the highest green mass productivity with tallness and high foliage of plants, as well as the greatest leaf length and hay yields.

Field trials were carried out on the basis of the FSBSI “ARC “Donskoy” in 2021–2023. Peas were used as a forecrop. In the trials there were studied 14 winter bread wheat varieties of the competitive variety testing conducted in the laboratory for breeding and seed production of winter bread wheat of semi-intensive type. The purpose of the current work was to study the effect of yield structure elements on the productivity of winter bread wheat varieties bred by the FSBSI “ARC “Donskoy” when sown after peas in the southern part of the Rostov region. Analysis of the results has shown that the yield of 2021–2023 varied from 7.34 t/ha for the standard variety ‘Don 107’ to 8.45 t/ha for the variety ‘Premiera’. During the period of work, there were estimated such structure elements as ‘number of productive stems’, ‘length of a head’, ‘number of spikelets in a head’, ‘number of grains in a head’, ‘grain weight per head’, ‘1000-grain weight’. The trait ‘number of productive stems’ varied from 600 pcs./m² to 720 pcs./m², the maximum values were obtained from the varieties ‘Ayuta’ (650 pcs./m²), ‘Volny Don’ (678 pcs./m²), ‘Polina’ (680 pcs./m²), ‘Region 161’ (681 pcs./m²), ‘Volnitsa’, ‘Donets’ (700 pcs./m²), ‘Flagman’ (702 pcs./m²), ‘Aksai’ (708 pcs./m²), ‘Premiera’ (718 pcs./m²), ‘Ambar’ (720 pcs/m²). During the studied period, the varieties were divided into such two groups according to the length of a head as ‘medium-headed (8–10 cm) including the varieties ‘Don 107’, ‘Zhavoronok’, ‘Podarok Krymu’, ‘Ayuta’, ‘Region 161’, ‘Volny Don’, ‘Flagman’ and ‘long-headed’ (more than 10 cm) including the varieties ‘Zolotoy Kolos’, ‘Polina’, ‘Donets’, ‘Volnitsa’, ‘Ambar’, ‘Premiera’, ‘Aksai’. The limits of variability in the trait ‘number of grains per head’ for the winter bread wheat samples ranged from 28.7 pcs. (‘Volny Don’) to 38.7 pcs. (‘Zolotoy Kolos’). The trait ‘grain weight per head’ of the standard variety ‘Don 107’ was 1.30 g, high values of the trait (НСР05 = ±0.05 g) were identified in such varieties as ‘Polina’ and ‘Donets’ (1.36 g), ‘Zhavoronok’ (1.39 g), ‘Zolotoy Kolos’ (1.45 g). The trait ‘1000-grain weight’ varied from 35.3 g (‘Podarok Krymu’) to 48.0 g (‘Donets’). Large grains were formed by the varieties ‘Zhavoronok’ (40.0 g), ‘Flagman’ (40.6 g), ‘Premiera’ (45.1 g), ‘Aksai’ (45.2 g), ‘Volnitsa’ (47.0 g), ‘Donets’ (48.0). Significant contribution to the formation of productivity of the new winter bread wheat varieties bred by the FSBSI “ARC “Donskoy” was made by the traits ‘1000-grain weight’ (r = 0.75±0.18), ‘length of a head’ (r = 0.66±0.21), ‘number of productive stems’ (r = 0.61 ± 0.22) and ‘grain weight per head’ (r = 0.57 ± 0.23).

Currently, in our country there is growing interest in the cultivation of high-tech pea varieties, which are characterized by uniform maturity, high productivity, and lodging resistance. Thus, breeding for lodging resistance is one of the most important criteria in pea breeding programs. The purpose of the current study was to search for anatomical indicators that could serve as a criterion when selecting pea samples for lodging resistance. The field trials were carried out in the fields of the laboratory for legumes breeding and seed production, the laboratory study was conducted in the laboratory for cell breeding of the FSBSI “ARC “Donskoy” in 2022–2023. The estimation of lodging resistance was carried out on 22 pea samples of the regional and foreign breeding. The studied samples differed in plant height, morpho-anatomical features of a stem structure, and lodging resistance. Based on the results of estimating an anatomical structure of a pea stem, there were identified such samples with a complex of traits (number of bundles, ratio of a number of bundles to stem tissues) as ‘Lu-153-06’, ‘G-1234’, ‘G-1193’, ‘G-1288’, ‘AKM’, ‘G-1313’, ‘Flagman 10’, ‘G-1313’. The analysis of correlations between anatomical indicators and field resistance to lodging has shown a high positive correlation with a stem height (r = 0.78±0.14), a mean negative correlation with a plant height (r = -0.66±0.17), and a mean positive correlation with a number of vascular bundles (r = 0.69±0.16). The experimental results allow concluding that the estimation of lodging resistance based on an anatomical structure of a pea stem is effective and can serve as a tester for lodging resistance.
