The current paper has presented a historical excursion and an overview of scientific research on breeding and seed production of winter and spring barley in the Federal State Budgetary Scientific Institution Agricultural Research Center “Donskoy”. The Southern Federal District includes 8 subjects of the Russian Federation, namely Sevastopol; republics of Adygea, Kalmykia, Crimea; Krasnodar Territory, Astrakhan, Volgograd and Rostov regions. Barley is the main grain forage crop in terms of sown area. Don farmers have long shown interest in this valuable, diverse crop, very unpretentious to the cultivation conditions. Barley breeding work began in our institution in 1932 and is still ongoing, with short interruptions, to the present. Research was carried out in various areas: breeding of winter, spring and facultative barley, seed production and technology of their cultivation. In the XXI-st century, the researchers of the barley department developed new innovative directions in barley breeding, there were developed two-row brewing varieties with high malting rates (the variety ‘Randevu’) in winter barley breeding and in spring barley breeding there were developed fodder barley (green fodder) varieties (the variety ‘Novik’), which were previously absent in the State List of the Russian Federation. In 2014 there were opened new directions in the department, namely the development of hulles spring barley varieties and awnless winter barley varieties. Since 2016, there has been carried out an active work to identify winter barley lines that are genetically resistant to net blotch. Together with the All-Russian Research Institute of Radiology and Agroecology, there was carried out an estimation of the radiosensitivity of winter and spring barley varieties to identify varieties being resistant to the environmental stress factors. Based on research materials, there were successfully defended 11 candidate and two doctoral dissertations, there were published eight monographs and more than 400 scientific articles.

Anther culture is one of the most popular methods for obtaining haploid triticale plants. The current paper has presented the study results of the efficiency of the method for obtaining haploid plants in promising winter triticale forms bred by the Federal Agricultural Research Center of South-East. There has been estimated haploproduction parameters for the studied genotypes on the nutrient media C-17 and P-2. There were no genotypes unresponsive to androgenesis. There has been found that the medium Potato-2 had a significant positive effect on the total number of embryogenic structures per 100 cultivated anthers in four of the six studied genotypes when the index increased in 1–3 times. The mean value of the EC/100KP indicator was 23.3 with a variation of 6.4-75.1. The largest number of ES (45.8 and 75.1) was found in genotype No. 96 (F5 Zimogor/win.br.wheat L.39) on induction media C-17 and P-2. The genotypes No. 95 and No. 97 were characterized by the lowest indicators F4 DH13/ win.br.wheat ‘Atkara’//Vodoley/ADP-2///Colina and F5 MAG/Vodoley//TI-17. Plant regeneration varied from 3.4 to 22.1 with an average value of 12.6 per 100 EC. The mean number of green plants per 100 EC was 3.9, varying from 0.4 to 12.1. The proportion of green plants, depending on the genotype, varied from 5.0 to 76.9 %. Two-way analysis of variance has identified the dominant role of the genotype at all stages of haploproduction. The proportion of effect of the nutrient medium was statistically significant, but insignificant in comparison with the genotype. There has been established that, along with genotypic dependence and albinism, the limiting factor of the method is a low frequency of regeneration of embryo-like structures. In total, there were obtained 949 regenerated plants out of 7538 embryogenic structures, of which 326 were green. The ratio of green plants to albinos was 1:2.

There have been presented the study results of the biochemical composition of the green mass of sandy sainfoin (Onobrychis arenaria) samples developed by the FSBSI Agricultural Research Center “Donskoy”. The purpose of the current study was to identify the variability of the content of raw nutrients: protein, oil, fiber, ash, BEV in the green mass of sainfoin varieties and lines, to determine the amino acid composition of protein and to identify the best samples for the studied traits. The study was carried out in the period of 2017–2021. The variety ‘Zernogradsky 2’ was used as a standard variety. Biochemical analyzes were carried out in the period ‘budding stage – blooming stage’. The chemical composition of the selected samples was carried out in accordance with the methodology and GOSTs. The maximum crude protein percentage was determined in promising lines ‘Sin 8/95’ (15.38 %) and ‘Sin 13/95’ (14.72 %). There was found that the varieties ‘Veles’ (10.6 %), ‘Atamansky’ (14.1 %) and the lines ‘Sin 13/95’ (11.8 %), ‘Sin 8/95’ (16.9 %) were characterized by a high concentration of raw ash. The optimal fiber content was established in the varieties ‘Atamansky’ (29.73 %) and ‘Veles’ (29.61%). As a result of determining the amino acid composition of protein, there was found that the line ‘Sin 8/95’ (68.5 g/kg) and the varieties ‘Zernogradsky 2’ (62.3 g/kg), ‘Veles’ (52.5 g/kg) were distinguished by the collection of essential amino acids. The varieties ‘Veles’ (75.0 g/kg), ‘Zernogradsky 2’ (66.5 g/kg) and the line ‘Sin 8/95’ (66.4 g/kg) were distinguished by the number of non-essential amino acids. The line ‘Sin 8/95’ (134.9 g/kg) and the varieties ‘Veles’ (127.5 g/kg), ‘Zernogradsky 2’ (128.8 g/kg) were characterized by a high total collection of amino acids. There was determined that crude protein percentage (from 4.3–18.4 %), fiber (7.8–16.9 %), dry matter (4.5–13.1 %) and BEV (9.6–15.9 %) were characterized by slight and medium variation in values. The content of crude ash (9.6–25.2 %) and crude oil (7.5–27.8 %) had weak, medium and strong variations depending on the variety and line. The study of the biochemical composition of sainfoin made it possible to establish varietal differences and variability of traits that characterize the nutritional value of the feed. The varieties ‘Veles’, ‘Zernogradsky 2’ and the promising line ‘Sin 8/95’ were found to have the best quality traits, which could be recommended for use in the breeding process as sources of useful traits and properties.

The current paper has presented the study results of the hybrid population of the second generation ‘Khao Hlan On × Kontakt’. The variety ‘Khao Hlan On’ is late-maturing, small-grained, fast-growing, of tall height, resistant to lodging, the variety ‘Kontakt’ is early-maturing, medium-grained, of low height, resistant to lodging. The purpose of the study was to analyze the inheritance of the main quantitative traits in the rice hybrid F2 ‘Khao Hlan On × Kontakt’ and select the best forms for breeding. In the course of genetic analysis, there have been determined the features of traits’ inheritance that affect productivity; there have been selected the best plants with an average height, with vertical panicles and mean grain weight. The study was carried out on the fields of the EP “Proletarskoe” (the Rostov Region) in 2022. For all the studied traits, there have been established the monogenic differences between the parental varieties. According to plant height, there was a partial domination of the lower values of the trait (hp = –0.22). According to panicle length, there was a partial negative dominance of the trait (hp = –0.35). According to the trait ‘number of spikelets per panicle’, there was a partial dominance of a smaller value of the trait (hp = –0.19). According to 1000-grain weight, there was a partial negative dominance (hp = –0.26). There have been selected the best morphotype F2 forms, which according to our earlier study, differed in optimal plant height, panicle length, number of spikelets per panicle, and 1000-grain weight.

In order to manage the phytosanitary situation on the sowings and get the maximum yields of high quality, at first it is necessary to estimate the condition of the protected crop. Based on this estimation, in future it is possible to establish the most effective and economically justified protection system. Grain crops are the most important strategic crops that ensure food security around the world. According to the FAO the world crop losses caused by pests have reached up to 40 % where fungal pathogens have played the most significant role. Therefore, the most important task of phytosanitary monitoring is the timely detection and identification of the disease before the beginning of symptoms at the earliest stages of pathogen development, which becomes possible when the infectious beginning of the disease has been detected. When monitoring fungal diseases, spore-catching equipment allow this issue to be solved. The purpose of the current review was to describe the existing developments of spore-catching equipment for monitoring grain crop diseases and to identify promising areas for using devices on crops to improve protective measures’ efficiency. The introduction has briefly described the classical methods of monitoring and the relatively new methods currently used. In the main part there has been considered a spore-catching equipment developed and used both in foreign and domestic practice. There have been analyzed the methods of using spore-catching equipment and given the examples of the use of these devices in monitoring crop diseases. In the conclusions there have been summarized the trends in the development of technical support for phytosanitary monitoring and shown areas that have been found promising for further research.

The current study was carried out in 2019–2021 using the material and technical base of the FSBSI Agricultural Research Center “Donskoy”, in order to research winter bread wheat samples of various ecological and geographical origin according to productivity and some economically valuable traits, to identify the most adapted of them for the conditions of the southern part of the Rostov region. The objects of the study were 17 winter bread wheat samples of ecological variety testing. The variety ‘Ermak’ was used as a standard. As a result of the study, there was found that the productivity of the samples (2019–2021) ranged from 7.75 (‘Etana’) to 9.52 t/ha (‘MV 15-04’). The standard variety ‘Ermak’ (8.20 t/ha) was exceeded by 9 samples ‘Akhmat’, ‘MONE’, ‘KIV – 6’, ‘Astarta’, ‘Slavna’, ‘Chornyava’, ‘XE 9710’, ‘MV 15-04’, ‘No. 71 CIMMYT’, the increase was from 0.45 to 1 .32 t/ha (0.42 t/ha with НСР05). According to ‘heading date’, the samples ‘KIV-6’, ‘Slavna’, ‘Chornyava’, ‘No. 71 CIMMYT’ (May 19–20) belonged to the middle-early maturing group; the samples ‘Akhmat’, ‘MONE’ (May 21–22) belonged to the middle-late maturing group; the samples Astarta, XE 9710, MV 15-04 (May 23–24) belonged to the late maturing group. According to ‘plant height’, the variation ranged from 81.5 cm (‘Akhmat’) to 100.3 cm (‘XE 9710’), the standard ‘Ermak’ had 99.5 cm. All studied samples belonged to a medium-large-grain-sized group (34.05–40.72 g) according to ‘1000-grain weight’. Through the years of study, the sample ‘No. 71 CIMMYT’ showed 0 points of powdery mildew resistance (defeat in the field). There have been identified the best septoria blight resistant samples ‘KIV-6’ (Russia) and ‘Astarta’ (Ukraine), with a damage degree of 5–10 %. The standard variety ‘Ermak’ had 30–40 %. As for yellow rust, the standard variety ‘Ermak’ was damaged on 50–60 %, the sample ‘No. 71 CIMMYT’ was damaged on 20–30 %; the sample ‘MONE’ on 5–10 %; the sample ‘KIV-6’ was damaged on 0–5 %; the remaining samples ‘Astarta’, ‘Slavna’, ‘Chornyava’, ‘XE 9710’ and ‘MV 15-04’ were resistant to this pathogen. According to the complex of economically valuable traits for practical breeding in the conditions of the south of the Rostov region, three winter bread wheat varieties ‘KIV-6’ (Russia), ‘Astarta’, ‘Slavna’ (Ukraine) have been of the greatest interest.

All studied samples belonged to a medium-large-grain-sized group (34.05–40.72 g) according to ‘1000-grain weight’. Through the years of study, the sample ‘No. 71 CIMMYT’ showed 0 points of powdery mildew resistance (defeat in the field). There have been identified the best septoria blight resistant samples ‘KIV-6’ (Russia) and ‘Astarta’ (Ukraine), with a damage degree of 5–10 %. The standard variety ‘Ermak’ had 30–40 %. As for yellow rust, the standard variety ‘Ermak’ was damaged on 50–60 %, the sample ‘No. 71 CIMMYT’ was damaged on 20–30 %; the sample ‘MONE’ on 5–10 %; the sample ‘KIV-6’ was damaged on 0–5 %; the remaining samples ‘Astarta’, ‘Slavna’, ‘Chornyava’, ‘XE 9710’ and ‘MV 15-04’ were resistant to this pathogen. According to the complex of economically valuable traits for practical breeding in the conditions of the south of the Rostov region, three winter bread wheat varieties ‘KIV-6’ (Russia), ‘Astarta’, ‘Slavna’ (Ukraine) have been of the greatest interest.","PeriodicalId":33209,"journal":{"name":"Zernovoe khoziaistvo Rossii","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46279590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study was carried out in order to identify the efficiency of direct (no-till) sowing of grain crops after potatoes on medium loamy gray forest soils with 2.33 % of humus, 210 mg/kg of mobile phosphorus, 162 mg/kg of exchangeable potassium and 6.6 units of acidity. The objects of study were winter and spring wheat, spring barley for brewing and fodder, maize for grain and silage. The sowing complex ‘Amazone Primera DMC’ has carried out direct (no-till) sowing of disease-treated seeds with the simultaneous application of mineral fertilizers. Grain crop treatment to control weeds, pests, and diseases, as well as top dressing with macro- and micro-fertilizers were aimed at obtaining the maximum productivity of each grain crop. The hydrothermal coefficient in the 2020 growing year was 1.04, in 2021 it was 0.60 and in 2022 it was 1.05. Harvesting was carried out in the phase of full ripening of grain and milky-wax ripeness of cobs when laying maize silage. On average, the largest (3.85 t/ha) grain productivity when using direct (no-till) sowing was produced by maize, and the least yields (2.00 t/ha) were given by brewing barley. In the production of these crops, there have been identified maximum (2.72) and minimum (1.99) energy efficiency coefficients. An economic estimation has shown the feasibility of direct (no-till) sowing of winter wheat, where the maximum (68.4 %) level of profitability was established. The minimum (14.8 %) level of profitability was found in the cultivation of brewing barley, which could be explained by the high degree of material and labor costs and low productivity. The profitability of the production of other crops was lower in 1.21-3.39 times. In general, agroeconomic and energy analysis has proved a high efficiency of direct (no-till) sowing in the cultivation of winter wheat and maize after potatoes in the agro-climatic conditions of the Republic Chuvashia.
本研究旨在确定在腐殖质含量为2.33%、流动磷含量为210 mg/kg、交换钾含量为162 mg/kg、酸度为6.6单位的中等壤土灰色森林土壤上马铃薯后直接(免耕)播种谷物作物的效率。研究对象为冬小麦和春小麦，酿造和饲料用春大麦，谷物和青贮用玉米。“Amazone Primera DMC”播种综合体在施用矿质肥料的同时，直接(免耕)播种了患病种子。粮食作物的杂草、病虫害防治和施用宏、微肥追肥的目的是使每一种粮食作物获得最大的生产力。2020生长期热液系数为1.04,2021年为0.60,2022年为1.05。玉米青贮时，在籽粒完全成熟和玉米棒乳蜡成熟阶段进行收获。直接(免耕)播种时，玉米产量最高(3.85 t/公顷)，酿造大麦产量最低(2.00 t/公顷)。在这些作物的生产中，已经确定了最高(2.72)和最低(1.99)的能源效率系数。经济估算表明，冬小麦直接(免耕)播种是可行的，其收益率最高(68.4%)。酿造大麦的利润率最低(14.8%)，这可以解释为材料和人工成本高，生产率低。其他作物的生产盈利能力较低，为1.21-3.39倍。总的来说，农业经济和能源分析证明，在Chuvashia共和国的农业气候条件下，马铃薯后种植冬小麦和玉米的直接(免耕)播种效率很高。

The efficiency of the anther culture method in vitro largely depends on the responsiveness of varieties and hybrids to the induction of androgenesis. The purpose of the current study was to estimate the efficiency of haploproduction of regenerated lines (R0) of winter bread wheat developed by anther culture in vitro and grown in a greenhouse. To achieve this goal, there was set a task to conduct a morphometric estimation of the developed heads (R0) to identify their fertility level. The study was carried out in the laboratory of cell breeding of the FSBSI Agricultural Research Center “Donskoy” in 2021–2022. The objects of the study were 7 hybrid combinations of winter wheat, which were responsive to androgenesis in vitro in the culture of isolated anthers. As a result of induced androgenesis on an artificial nutrient medium, there were identified 333 neoplasms, represented by calluses, embryoids and embryogenic complexes. Green regenerated plants were vernalized in test tubes, cloned, diloidized, then planted into soil. There were obtained 13 haploid lines, after diploidization only 34 plants survived. The highest haploproductive capacity was established in the hybrid combination F3 ‘Rostovchanka 7xBezostaya 100’. In this combination, there were formed 8 green regenerants, 21 plants of which were developed together with clones, 18 of which survived. The cytometric estimation has shown, that 25 dihaploid (2n = 42) and 16 haploid (n = 21) wheat plants have been identified by hybrid combinations, including 13 dihaploids from the combination ‘Rostovchanka 7xBezostaya 100’. As a result of the structural analysis and morphometric estimation of the head there has been found a different fertility degree of androgenic regenerated plants. There have been established prospects of using the dihaploid line ‘79.2.1.2’ in further breeding work based on the hybrid combination F3 ‘Rostovchanka 7xBezostaya 100’ with the highest values of such yield elements as ‘number of heads’, ‘number and weight of grains per head’.

The study of ten parental forms of maize hybrids was carried out in 2017–2019 at five testing establishments with contrasting weather conditions, namely FSBSI Agricultural Research Center “Donskoy”, Rostov Region; FSBSI “All-Russian research institute of maize”, Stavropol Territory; Povolzhsky branch of FSBSI ARRIWG, Volgograd region; FSBSI “All-Russian research institute of maize” (Voronezh branch), Voronezh Region; LLC "Leader", Volgograd region. The purpose of the current study was to estimate the parameters of environmental adaptability and stability, using contrasting moisture points, to evaluate the productive potential of parental forms, i.e. sterile simple maize hybrids to optimize their further use in the breeding and seed production process. The parental forms formed the maximum grain productivity in the Voronezh branch of the All-Russian research institute of maize, where there were formed the most favorable conditions with the environmental index Ij = +2.2; the smallest productivity was formed under the conditions of the ARC “Donskoy” with Ij = –2.3. There have been identified the parental forms (‘Maya M’ and ‘Prestizh M’) with a high potential grain productivity (9.1…9.5 t/ha). There have been identified the parental forms ‘Almaz M’, ‘Avrora S’, ‘Milena M’, ‘Mirt M’, ‘Malvina S’, ‘Raduga S’, ‘Prestizh M’, ‘Maya M’ with high environmental adaptability (bi = 1.03…1.37), high responsiveness to favorable growing conditions. They have been recommended to be used to develop maize hybrids of intensive type. Among them, there have been identified the most adaptable hybrids ‘Mirt M’ and ‘Prestizh M’ with Ymax+Ymin = 6.2…6.8. There have been identified the parental forms ‘Alfa M’ and ‘Istok S’ with low adaptability (bi = 0.76...0.77), but at the same time with high environmental adaptability (σ2d = 0.16...0.20) and high stress resistance (Ymin–Ymax = –3.0…3.1). They have been found preferable for breeding maize hybrids of extensive type for growing under less favorable conditions. The hybrid ‘Istok S’ (Hom = 4) was characterized by the best homeostasis.

It is possible to solve the problem of productivity and improve the gross harvest of agricultural products by introducing new varieties and hybrids adapted to the conditions of cultivation into production. The diversity of the varietal composition of sorghum crops necessitates a careful approach in the selection of varieties. This is especially important for the North Caucasus region, which is characterized by contrasting natural and climatic conditions. The purpose of the current study was to analyze the existing varietal range of grain, sweet, grass sorghum, to identify varieties recommended for cultivation in the North Caucasus region. The work on the development of sorghum crops was carried out at the Federal State Budgetary Scientific Institution “ARC “Donskoy” in accordance with the Methodology of the State Commission for Variety Testing of Agricultural Crops. There has been found that since 2013 20 grain sorghum varieties and hybrids of Russian originators (7 sugar sorghum varieties, 6 Sudan grass varieties, 7 sorghum-Sudan hybrids) have been approved for cultivation in the North Caucasus region of the Russian Federation. Since 2013 2 grain sorghum varieties, 2 sweet and Sudan grass varieties, 1 sorghum-Sudan hybrid have been developed and introduced into the Register at ARC “Donskoy”. There have been developed grain sorghum varieties ‘Zernogradskoye 88’, ‘Esaul’ which are distinguished by high grain productivity of 5.0–6.2 t/ha and have been recommended for use for feed and food purposes. Sweet sorghum varieties ‘Feniks’ and ‘Yuzhnoe’ have been characterized by a large productivity of green mass for silage (37–45 t/ha) and good feed qualities, which allows them to be used for silage production. Sudan grass varieties ‘Alisa’ and ‘Gratsiya’ have made it possible to obtain 2 cuttings of high-quality green fodder (39–44 t/ha) and hay (12.0–13.2 t/ha). The sorghum-Sudan hybrid ‘Dobrynya F1’ has 55–61 t/ha of green mass for two cuttings and could be recommended for use for green fodder, hay, silage.
