The current paper has provided data on the study of the vascular system of flag leaves of rice plants grown in a greenhouse in the period 2022–2023. The objects of the study were 24 rice samples developed at the FSBSI “ARC “Donskoy” using the method of androgenesis and cell culture. The purpose of the work was to determine the degree of development of the vascular system of flag leaves of regenerated rice plants with different ploidy levels (1n, 2n, 4n). When studying the vascular system of plant leaves (the number and area of bundles), it was found that haploid plants had smaller vascular bundles compared to diand tetraploid samples. The average beam diameter had dimensions of 59.5, 69.3 and 75.3 µm, the area of one beam was 2815.6, 3827.2 and 4540.5 µm², respectively. In the leaves of rice samples, a larger number of small and large vascular bundles have been formed with increasing ploidy level. Their number was 36–44 in haploids, 40–52in diploids, 52–60 in tetraploids. The average number of bundles was 40.3, 46.6 and 55.2, respectively. The venation pattern was individual for each sample. Between single large bundles there are from one to seven small veins, most often 4–6 pieces. Thus, samples with different ploidy levels differ in the anatomical structure of the leaves, which ultimately affects their morphology and productivity.

Currently, solving the problem of improving agricultural crops’ productivity is of great relevance. The parameters of photosynthetic activity play an important role in photosynthesis and ensure the efficient functioning of plants under various conditions. Understanding of these processes helps better understand the mechanisms of plant growth and development, as well as develop methods to increase productivity and resistance to stress conditions. The purpose of the current study was to estimate the effect of biofertilizers on the functioning of the photosynthetic apparatus and the variability of the area of leaf blades of agricultural grain crops (durum wheat, spring barley), and to establish the dependence of productivity on the ameliorant used. The objects of study were the spring barley variety ‘Anna’ and the durum wheat variety ‘Orenburgskaya’. The area of the leaf blade was measured by scanning using the APFill Ink&Toner Coverage Meter program. To determine the chlorophyll content, there was used a portable N-tester. There has been reliably established positive correlation between productivity increase and the size of the leaf blade of the experimental plants. The application of the studied biofertilizer has had a positive effect on chlorophyll increase in the barley leaf blades. This explains the possibility of changing the studied parameters by agricultural methods (fertilizer application). There has been found a significant correlation (at p˂0.05) between the height parameters with a number of seeds in a head (r = 0.63) and a leaf blade area (r = 0,69), a number of seeds in a head and productivity (r = 0.86). As a result of the study, there has been established a relationship between some quantitative parameters of the seed material (head length – number of seeds in a head), and a positive correlation was identified between a leaf area and a head length (r = 0.69). There has been obtained a significant dependence of barley productivity on the ameliorant used. At the same time, the productivity increase when using fertilizer compared to the control was 58.9 %.

The purpose of the current study was to establish the effect of sowing rates of spring durum wheat on its productivity. There has been established that reducing seed sowing rates from 7 to 3 million germinated seeds per 1 ha allows reducing spring durum wheat vegetation period by 6–7 days. There has been identified maximum density of productive stems of the two varieties at a seeding rate of 6 and 7 million germinated seeds per 1 ha. The highest productive tillering capacity for two spring durum wheat varieties was obtained at the variant with a norm of 5 million germinated seeds per 1 ha. Thus, according to the experimental variants, the average plant height of the variety ‘Bezenchukskaya Niva’ was 70.6 cm in the control variant and 81.8 cm at a sowing rate of 5 million germinated seeds per 1 ha. The variety ‘Bezenchukskaya Zolotistaya’ has produced the tallest plants of 79.5 cm, with a seeding rate of 4 million germinated seeds per 1 ha. There has been established that the length of a head also increases with a seeding rate decrease; for example, in the variety ‘Bezenchukskaya Niva’, the maximum indicators of the main head were formed at a seeding rate of 5 million germinated seeds per 1 ha, where the maximum length of the main head was 6.7 cm, the number of grains was 27.5 pieces with a weight of 1.47 g. For the variety ‘Bezenchukskaya Zolotistaya’, the maximum head length was 5.6 cm, and the number of grains was 24 pieces at a rate of 4 million germinated seeds per 1 ha. The fullest grain of the variety ‘Bezenchukskaya Niva’ with 53.4 g of ‘1000-grain weight’ was formed at a seeding rate of 5 million germinated seeds per 1 ha; the variety ‘Bezenchukskaya Zolotistaya’ was 50.4g with a norm of 6 million germinated seeds per 1 ha. The maximum productivity of the variety ‘Bezenchukskaya Niva’ was 3.54 t/ha with a seeding rate of 5 million germinated seeds per 1 ha. The variety ‘Bezenchukskaya Zolotistaya’ formed a yield of 3.23 t/ha with a seeding rate of 6 million germinated seeds per 1 ha.

There have been given the study results of grain color characteristics of winter durum wheat varieties and lines (Triticum durum Desf.). There has been studied the effect of factors (‘variety’, ‘year’ and their correlation) on the expression of the main breeding-valuable traits that affect the quality of the final product. The purpose of the current study was to determine the variability of phenotypic characteristics of grain associated with the number of yellow pigments in grain, the color of semolina and finished pasta, to study the correlation between indicators and to identify the most promising ones for further work. Field trials were carried out in the scientific crop rotation laboratory of breeding and seed production of winter durum wheat of the FSBSI “ARC “Donskoy”. Laboratory and analytical study was carried out in the laboratory of biochemical, technological and agrochemical estimation in accordance with generally accepted methods and GOST. As a result of the study, there has been established that the main effect on such characteristics of grain quality of winter durum wheat as ‘general hardiness’, ‘mass fraction of protein in grain’ and ‘grain color index b’ was produced by the factor ‘year of study’ by 67.0 %, 48 .2 % and 65.4 % respectively. The ‘cereal color index b’, ‘dry pasta color index b’ and visual estimation of dry pasta were mainly influenced by the factor ‘genotype’ by 62.3 %, 82.5 % and 48.3 %, respectively. The severity of the trait ‘content of carotenoid pigments’ depended on all factors. Over the years of the study, the winter durum wheat varieties and lines developed by the FSBSI “ARC “Donskoy” according to color characteristics met the international requirements for durum wheat grain. As a result, the varieties ‘Grafit’ and ‘Karotinka’ stood out according to several studied characteristics in connection with which we recommend expanding the production crops of these varieties. There can be recommended to use promising lines 1147/19 and 971/19 and the variety ‘Solntsedar’ in the breeding process as sources with high color characteristics of grain and pasta.

The development and wide distribution of new adaptive varieties in production is a promising and environmentally friendly way for the development of agriculture. A new, more modern, highly productive variety can ensure increased productivity, resistance of crops to stress factors, and promotes better use of natural and anthropogenic resources. The leading direction in breeding in the nearest future should be not the development of varieties in general, adapted to growing conditions, but the identification of varieties adapted to the stress-limiting environmental factors of a particular region, adaptive to the challenges of nature. In addition to the characteristics of the variety and environmental conditions, the forecrop also influences its productivity. Selection in some conditions may not reveal the potential of the genotype in others, which makes it important to obtain information on different growing environments of varieties at the early stages of breeding. The purpose of the current study was to determine the adaptive properties of promising winter barley varieties and lines according to various forecrops. The study was carried out from 2021 to 2023 to estimate the adaptability parameters of 20 winter barley varieties and lines developed by the FSBSI Agricultural Research Center “Donskoy” for various forecrops (weedfree fallow, peas, sunflower, winter wheat). To determine the indicators of homeostaticity (Hom) and selection value (Sc), stress resistance (Ymin–Ymax) and genetic flexibility ((Ymax+Ymin)/2), the coefficient of responsiveness to favorable growing conditions (Kr) and the indicator of the stability level of the variety (VSLI), there have been applied the methods of V.V. Khangildin and N.A. Litvinenko (1981), A.A. Rosielle and J. Hamblina as presented by A.A. Goncharenko (2005), V.A. Zykin (2005), E.D. Nettevich (2001). According to all forecrops, there have been identified the varieties distinguished by high parameters of environmental adaptability and stability. Stress-resistant genotypes included the lines ‘Parallelum 2016’ and ‘Parallelum 2017’ (Ymin–Ymax = 1.2, 1.1, respectively), which were distinguished by a set of stability indicators and have been recommended for use in the breeding process as sources of high stress resistance, low yield variability, capable of minimizing negative impact of growing conditions. The variety ‘Step’ proved to be adaptable (regression coefficient bi = 1.5), genetically flexible ((Ymin–Ymax)/2 = 7.7), and highly responsive to growing conditions (Kr = 1.53). The dynamics of productivity corresponded to changes in growing conditions, and to maximize a productivity level, there has been recommended to cultivate it on intensive forecrops.
开发适应性强的新品种并在生产中广泛推广，是农业发展的一条大有可为的环保之路。更现代化、高产的新品种可确保提高生产力，增强作物对胁迫因素的抵抗力，并促进更好地利用自然和人为资源。在不久的将来，育种的主导方向不应是开发适应生长条件的一般品种，而应是确定适应特定地区胁迫限制环境因素的品种，以适应大自然的挑战。除了品种特性和环境条件外，前作也会影响其产量。在某些条件下进行的选育可能无法揭示基因型在其他条件下的潜力，因此在育种早期阶段获取品种不同生长环境的信息非常重要。本研究的目的是根据各种前茬作物确定有潜力的冬大麦品种和品系的适应性。研究时间为 2021 年至 2023 年，目的是估算由 FSBSI "顿斯科伊 "农业研究中心培育的 20 个冬大麦品种和品系对各种前茬作物（无杂草休耕地、豌豆、向日葵、冬小麦）的适应性参数。为了确定平衡性指标（Hom）和选择值指标（Sc）、抗逆性指标（Ymin-Ymax）和遗传灵活性指标（(Ymax+Ymin)/2）、对有利生长条件的反应系数（Kr）和品种稳定性指标（VSLI），应用了 V. V. Khangildin 和 N. N. N. N. 的方法。V. Khangildin 和 N.A. Litvinenko (1981)、A.A. Rosielle 和 J. Hamblina（A.A. Goncharenko (2005)、V.A. Zykin (2005)、E.D. Nettevich (2001)提出的方法。在所有前茬作物中，已确定了环境适应性和稳定性参数较高的品种。抗逆基因型包括品系 "Parallelum 2016 "和 "Parallelum 2017"（Ymin-Ymax 分别为 1.2 和 1.1）。事实证明，品种 "Step "适应性强（回归系数 bi = 1.5），遗传灵活（（Ymin-Ymax）/2 = 7.7），对生长条件反应灵敏（Kr = 1.53）。生产力的动态变化与生长条件的变化相一致，为了最大限度地提高生产力水平，建议在集约化前茬作物上种植该品种。

Increasing interest among agricultural producers in Sarepta spring mustard as a promising, multi-purpose crop requires improving the elements of its cultivation technology to obtain consistently high yields. The current study was carried out in 2021–2022 on the experimental fields of the central experimental base of the FSBSI “FRC “All-Russian Scientific Research Institute of Oil Crops by the name of Pustovoit V. S.”. The purpose of the research was to study and scientifically substantiate individual elements of the technology (sowing time, seed sowing rate and level of mineral nutrition) for Sarepta mustard’s cultivation on seed productivity of the crop grown on leached blackearth (chernozem) of Western Ciscaucasia. There has been established that the highest yield (1.42 t/ha) and oil yield (0.60 t/ha) of the crop is obtained at an early sowing time (the first term (early) is in the 2nd decade of April) with a minimum seed sowing rate (1.3 million units/ha). Sarepta spring mustard’s single feeding of with ammonium nitrate at a dose of N60 in the seedling phase has helped to obtain maximum yield of 2.08 t/ha and 0.87 t/ha of oil. But the largest oil content in seeds (47.1 %) was identified in the variant with the application of nitrogen fertilizer at a dose of N30 fractionally in equal parts, i.e. in the stages of germination (N15) and booting (N15). Foliar treatment of Sarepta spring mustard with helium mixtures (Micro gel at a dose of 1 l/ha and Brassica gel at a dose of 2 l/ha) in the booting stage allowed obtaining the highest yield of 1.85 t/ha, with 47.9 % of oil in seeds and 0.80 t/ha of oil yield.

Sarepta spring mustard’s single feeding of with ammonium nitrate at a dose of N60 in the seedling phase has helped to obtain maximum yield of 2.08 t/ha and 0.87 t/ha of oil. But the largest oil content in seeds (47.1 %) was identified in the variant with the application of nitrogen fertilizer at a dose of N30 fractionally in equal parts, i.e. in the stages of germination (N15) and booting (N15). Foliar treatment of Sarepta spring mustard with helium mixtures (Micro gel at a dose of 1 l/ha and Brassica gel at a dose of 2 l/ha) in the booting stage allowed obtaining the highest yield of 1.85 t/ha, with 47.9 % of oil in seeds and 0.80 t/ha of oil yield.","PeriodicalId":508743,"journal":{"name":"Grain Economy of Russia","volume":"32 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140260520","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}

Work on developing a new pea variety ‘Krasnoufimsky 20’ began in 2008 on the experimental fields of the Krasnoufimsky breeding center of the Ural Research Institute of Agriculture, a branch of the FSBSI UrFARC UrO RAS. The purpose of the current study was to develop a highly productive pea variety that is resistant to negative environmental conditions, resistant to diseases and pests, and has a non-lodging stem and non-shedding seeds. The greatest productivity excess of the variety ‘Krasnoufimsky 20’ compared to the standard was observed in 2017, 2019, 2021 and 2022 (from 11 % to 62 %). On average, ‘Krasnoufimsky 20’ gave a significant excess over the standard by 0.26 t/ha. The variety ‘Krasnoufimsky 20’ requires weather conditions in the HTC range of 1.0–2.1 to obtain stable productivity. But regardless of environmental factors, both in favorable conditions and during periods of waterlogging or drought, the variety ‘Krasnoufimsky 20’ exceeded the standard by 0.03–0.83 t/ha. The variety ‘Krasnoufimsky 20’ ripened 1–3 days earlier than the standard, it has a larger number of beans and seeds per plant (by 0.2 and 1.5 pieces, respectively). The variety ‘Krasnoufimsky 20’ has a high seed productivity per plant (2.3 g). The variety is affected with ascochyta blight and root rot at the standard level, its damage by the codling moth is less than the standard. The new variety ‘Krasnoufimsky 20’ exceeded the standard variety Krasnoufimsky 11 and other varieties of local breeding according to adaptability. In 2023, it was decided to include the new pea variety ‘Krasnoufimsky 20’ in the State List of Breeding Achievements approved for use in the regions of Volga-Vyatka, North Caucasus, Ural, West Siberian.

The purpose of the current study was to identify the optimized seeding rate of the spring barley variety ‘Lyuboyar’ to obtain an economically profitable yield in the conditions of the non-blackearth part of the Central region of the Russian Federation on dark gray forest soils of a mean fertility level. The trials were carried out in the conditions of the Ryazan region in the selection crop rotation when sown in “black” fallow in 2022–2023. The trial scheme included the study of 6 options: 3.0; 3.5; 4.0; 4.5; 5.0 and 5.5 million germinating seeds per 1 hectare. There has been established that the optimal option in terms of field germination and preservation of plants for harvesting is the norm of 4.0 million per 1 ha with 89.5 % and 77.5 %, respectively. The number of survived plants before harvesting, the number of productive stems, plant height, head length, number of grains per head and grain weight per head have a significant contribution to crop productivity (r = +0.727...+0.955). The maximum number of stems (924 pcs/m2) and head length (9.2 cm) was demonstrated by the variant with a seeding rate of 4.5 million, height (83 cm) with 5.0 million, productive tillering (3.1) with 5.0–5.5 million, number of grains per head (23.9 pcs.) with 4.0 million, weight of grain per head (1.2 g) with 4.0–4.5 million, 1000-grain weight (47.5 g) with 3.0 million seeds per hectare. It was found that with an increase in the seeding rate, the number of plants increases before harvesting, the number of productive stems, plant height, tillering coefficient and head length increase with r = +0.543...+0.889, but there has been a decrease in indicators such as head weight (r = -0.355) and, especially, 1000-grain weight (r = -0.752). The largest productivity of 7.05 t/ha was obtained with a seeding rate of 4.0 million seeds per hectare, in the second place there was 6.90 t/ha with a rate of 4.5 million seeds per ha. At seeding rates of 4.0–4.5 million germ. seeds per 1 ha, the highest profitability was 67.2–60.2 %.

In the conditions of the Ryazan region there have been studied 64 spring common wheat varieties from the collection of the Federal Research Center VIGRR named after Vavilov in order to identify valuable traits for use in breeding. Field trials were carried out in the collection nursery on dark gray forest heavy loamy soil in 2018–2022, using the methodological recommendations of the Federal Research Center VIGRR named after Vavilov. There has been established that the highest yields (more than 5.0 t/ha) were formed by the varieties ‘Arseya’, ‘Maestro’ (Ryazan region), ‘KWS Akvilon’, ‘Ethos’ (Germany), ‘KWS Torridon’ (Great Britain), ‘Odeta’ (Czech Republic), ‘Calispero’ (France), which was on 29.9–49.9 % higher than the mean variety productivity in the trial. Yield stability with the least variation (Cv) was established for the varieties from the Central region – RIMA, ‘Arseya’ (Ryazan region), ‘Zlata’ (Moscow region) and ‘Omskaya 36’ (West Siberian region) with 3.1–9.6 %. The studied assortment of plant heights was divided into groups, such as dwarfs (< 60 cm) – 4.7 %, semi-dwarfs – 12.5 %, medium-sized – 75.0 %, tall – 7.8 %. There were identified 8 early ripening varieties ‘Chelyaba 2’ (Chelyabinsk region), ‘Odeta’ (Czech Republic), ‘Zlata’ (Moscow region), ‘Novosibirskaya 29’, ‘Novosibirskaya 15’, ‘Polyushka’ (Novosibirsk region), ‘M-83-1531’ (USA), ‘Burlak’ (Ulyanovsk region). The varieties ‘Voevoda’ and ‘Favorit’ (Saratov region) showed high resistance to various pathogens. There has been found a strong correlation between productivity and the density of productive stems with r = 0.753±0.084. 0.808±0.075, an average correlation with a number of grains per head with r = 0.427±0.115. 0.716±0.089 and grain weight per head with r = 0.374±0.118...0.689±0.092. Grain weight per head was largely determined by a number of grains per head with r = 0.621±0.099. 0.824±0.072.
