Complete genome characterization by nanopore sequencing of rotaviruses A, B, and C circulating on large-scale pig farms in Russia.

Rotaviruses are the major etiological agents of gastroenteritis and diarrheal outbreaks in plenty of mammalian species. The genus Rotavirus is highly diverse and currently comprises nine genetically distinct species, and four of them (A, B, C, and H) are common for humans and pigs. There is a strong necessity to comprehend phylogenetic relationships among rotaviruses from different host species to assess interspecies transmission, specifically between humans and livestock. To reveal the genetic origin of rotaviruses from Russian pig farms, nanopore-based metagenomic sequencing was performed on the PCR-positive specimens. Samples were selected among the cases submitted to routine diagnostic or monitoring studies to the Laboratory of Biochemistry and Molecular Biology of "Federal Scientific Center VIEV" (Moscow, Russia). The selected positive samples were genotyped using nanopore sequencing method. Five porcine RVA isolates were completely sequenced, and genotype analysis revealed various porcine G/P genogroups: G2, G3, G4, G5, G11 and P[6], P[7], P[13], P[23], P[27] with a typical backbone constellation I5-R1-C1-M1-A8-N1-T1/7-E1-H1. The RVB isolate was detected in combination with RVA in a rectal swab from a diseased pig in Krasnoyarsk Krai. It was characterized by the following genogroups: G15-P[X]-I11-R4-C4-M4-A8-N10-T4-E4-H7. The first complete porcine RVC genome from Russia was obtained with genomic constellation G6-P[5]-I14-R1-C1-M1-A7-N9-T6-E1-H1, and the phylogenetic analysis revealed putative novel genotype group for the VP6 gene-I14. Additionally, the first porcine kobuvirus isolate from Russia was phylogenetically characterized. The applied nanopore sequencing method successfully genotyped the RV isolates and additionally revealed co-circulated species. The study demonstrates high genetic variability of Russian RVA isolates in VP4/VP7 genes and phylogenetically describes local RVB and RVC. Complete characterization of genomic segments is a crucial methodology in tracing the rotavirus's evolution and evaluating interspecies transmissions.

Artificial Intelligence in Lung Cancer Detection: Clinical and Economic Assessment of Retrospective CT Analysis Two Years Post-COVID-19 Pandemic

BACKGROUND: The use of chest computed tomography (CT) scans in Krasnoyarsk Krai, Russia, has increased since 2020, during the COVID-19 pandemic. This period also saw a 5.2% decrease in lung cancer (LC) incidence. The potential for missed LC cases has led to the investigation of new diagnostic methods, including the use of artificial intelligence (AI) for analyzing retrospective data. AIM: The study aimed to evaluate the effectiveness of an AI algorithm in identifying patients at high risk for LC using chest CT data from the COVID-19 pandemic. METHODS: A retrospective analysis was conducted on chest CTs from patients diagnosed with COVID-19 in the Krasnoyarsk region, using scans from November 1, 2020, to February 28, 2021. The AI algorithm "Chest-IRA" was applied to detect pulmonary nodules larger than 100 mm³. Radiologists classified the nodules detected by AI into three categories based on LC probability. The economic assessment of the AI algorithm included salary costs and potential savings from early LC treatment. RESULTS: Out of 10,500 CTs, the AI algorithm found nodules in 484 cases. Of these, 192 were highly likely to have LC, 103 showed no signs, and 60 were inconclusive. 112 patients with high or intermediate risk did not seek treatment. The AI confirmed lung cancer in 100 cases, 28.2% of those detected. Early-stage LC was found in 35% of cases, while 65% were at later stages. AI could save about 25.04 months of radiologist work, costing 2.43 million RUB. Early detection savings are estimated at 10.6 to 12.5 million RUB per 10,500 CTs, with a five-year economic impact of 259.4 to 305.1 million RUB. CONCLUSION: AI has proven effective in identifying pulmonary nodules amidst COVID-19, highlighting its potential to improve early detection and diagnostic accuracy, leading to earlier and more precise treatments.

Impact of investments in mining on economic growth of Krasnoyarsk Krai

Aim. To evaluate the impact of investments in mineral extraction on the economic growth of Krasnoyarsk Krai using the dynamics of data for 2004–2021.Objectives. To prepare initial data for modeling in comparable prices; to build statistical models with a time lag; to determine the multiplier and gas pedal coefficients of investment; to demonstrate the possibilities of applying the obtained dependencies.Methods. The authors used the method of economic and mathematical modeling, in particular the calculation of socio-economic indicators using mathematical statistics. The regression model was built using the initial data that meet the requirements of comparability and homogeneity, are relevant and statistically reliable.Results. Dependencies reflecting the investment multiplier effect, i.e. the increase in the gross regional product (GRP) and the volume of shipped products in response to the increase in investment in mining were obtained. Dependencies reflecting the investment gas pedal effect are also obtained, showing how increased income affects the size of investment. The dependencies are applied to solve a number of practical problems.Conclusions. It has been established that investments in mining in Krasnoyarsk Krai have an impact on the growth of GRP and the volume of shipped products. The return on investment has a temporary character. The strongest impact of investments in the current year have on the growth of GRP and shipped products for the next year. The multiplier coefficient is 2.72. Increased income affects the size of investments: the growth of income from mining stimulates the growth of induced investments in the following year with the multiplier coefficient, which is equal to 0.14. The comparison of actual values of investments in mineral resources extraction and volume of shipped products with the target values laid down in the Strategy of socioeconomic development of the region until 2030 has been carried out. The target values, according to the Strategy, are determined with the help of the obtained dependencies. It was established that the actual volume of investments is sufficient to ensure the GRP growth in accordance with the Strategy at the first stage; to ensure growth at the second stage it is necessary to increase investments by 12–15 % annually; to ensure growth at the third stage it is necessary to increase investments by 9–13 % annually from the current state. In order to ensure the values of indicators on the volume of production provided for in the Strategy, it is necessary to increase output by 4–6 % annually compared to 2021.

GENETIC DETERMINANTS OF CARBOHYDRATE METABOLISM: INTRA- AND INTERETHNIC VARIABILITY OF THE LACTASE LCT, TREHALASE TREH AND SUCRASE-ISOMALTASE SI GENES IN THE EVENKI AND OTHER INDIGENOUS PEOPLES OF SIBERIA

Introduction. The authors consider the features of genetic determinants of disaccharide assimilation as the corollary of adaptation to the environment. The aim of the study was to assess the polymorphism of the genes that determine activity of disaccharidase enzymes lactase (LCT, rs4988235), trehalase (TREH, rs2276064) and sucrase-isomaltase (SI, rs781470490) in different territorial groups of Evenks. Materials and methods. Biomaterial samples from 1365 unrelated individuals representing 15 ethno-territorial population groups in European Russia, Siberia, and the Far East of the Russian Federation were genotyped. "Focus" groups include "Western" (N=65), "Transbaikal" (N=50), and "Okhotsk" (N=81) Evenks (Krasnoyarsk Krai, Northern Transbaikalia, Okhotsk-Aldan region). The other study groups allow us to assess the specificity of the distribution of genetic determinants of disaccharide assimilation in populations that differ from racial, ecological, and subsistence perspectives. Results. The Evenki territory subgroups do not differ from each other in terms of allele frequencies and genotype distribution of LCT (p>0.2) and TREH (p>0.8) and are similar to Yakuts, Buryats, Mongols, and populations of the Far East and Chukotka. The SI delAG deletion was not found in the Western Evenki subgroup. Discussion. A question of similarity between taiga hunters Evenks to cattle breeders Buryats, Mongols, and Yakuts in terms of C*LCT frequencies requires further elaboration. Possible explanations may include a weakening of selection for the T*LCT allele due to the shift in traditional diet toward replacement of fresh milk with fermented dairy products, high activity of specific intestinal microflora, or the existence of other lactase synthesis genetic determinants, besides LCT*C/T-13910. The evolutionary origins of the clinal variation in the TREH gene allele frequencies, which appears to be associated with the expression of the Mongoloid ancestral component in the gene pool of populations in Northern Eurasia, remain unclear. It seems appropriate to conduct genetic screening in the indigenous populations of the Russian Far East in order to assess the prevalence of SI delAG deletion as an inducer of the sucrase-isomaltase deficiency.

Post-project monitoring: the experience of the Krasnoyarsk Regional Fund of Science and Technology Support

Introduction: due to the current geopolitical situation, the results of scientific research must go far beyond the fundamental level and find application in the real sector of the economy. This is a key vector of the national scientific and technological policy, justified by the urgent need for import-substituting technologies that have emerged as a result of the global crisis, the COVID-19 pandemic and sanctions pressure. The research focuses on analyzing the development of scientific and scientific-technical projects after they have received state support. Objectives: to analyze the experience of the Krasnoyarsk Regional Fund of Science and Technology Support in monitoring the projects' relevance. Methods: post-project monitoring, continuous questionnaires, statistical and graphical analysis, and system analysis. Results: an analysis of the development of projects that received state support, conducted using post-project monitoring, showed that 8% of the total number of respondents commercialized the results of their projects, 37% introduced their results into socio-economic turnover in organizations operating in the Krasnoyarsk Krai. Conclusions: more than a third of all projects supported by the Krasnoyarsk Regional Fund of Science and Technology Support have received some form of further development or practical application in one form or another, which exceeds the average statistical data provided in other studies. However, there is still a need to increase the level of commercialization of scientific projects' outputs. The authors proposed a number of measures to achieve this goal.

Fauna and Ecology of Macromycetes (Basidiomycota) in the Arctic Tree and Shrub Ecosystems of Central Siberia.

The research was aimed at studying the taxonomic diversity, habitat specialization, and trophic characteristics of mycobiota, including Basidiomycota, in the northern ecosystems of the Krasnoyarsk Krai (Central Siberia) near Norilsk. Larch forests and woodlands in the Siberian permafrost zone are distinctive and Basidiomycota, as a component of these ecosystems, plays an essential role in their functioning. Currently, there is a paucity of information about this group in Arctic ecosystems, both in terms of floristic and ecological aspects. Seventy species of macromycetes belonging to different trophic groups were discovered and identified. Only 15% of species occur regularly, while most species are found rarely or only once. The identified species belong to 44 genera, 25 families, and 8 orders, which are included in the class Agaricomycetes. The leading families in terms of the number of species are Russulaceae, Polyporaceae, Tricholomataceae, Suillaceae, Strophariaceae, and Cortinariaceae. Mycorrhizal fungi and wood decay fungi dominate the structure of mycobiota of the study area (the total share is 71%). The rest of the species (29%) are fungal decomposers inhabiting plant litter, the forest floor, and humus. The largest number of species occur in forest ecosystems, which are dominated by mycorrhizal and wood decay fungi (up to 70%), which are trophically associated with woody plants and debris. The fungal decomposers inhabiting plant litter, the forest floor, and humus dominate (about 80%) in the species composition of tundra, where, in the absence of woody substrate, wood decay fungi have not been found at all. The species richness of tree and shrub Arctic ecosystems is low, yet the taxonomical and ecological structure of Basidiomycota is similar to that observed in taiga and temperate forests. These data permit a more comprehensive description of the biodiversity of the Arctic and may prove useful in studying biological processes in these ecosystems.

Инновационный потенциал регионов арктической зоны Российской Федерации: состояние и пространственная дифференциация

The article considers the components of the innovation potential of Russian regions that are fully or partially included in the Arctic zone. The purpose of the article is to analyze and evaluate the state and dynamics of innovative development of the regions of the Arctic zone of the Russian Federation. The methodology for calculating the composite index of innovative development is proposed. The calculations are made on the basis of the database formed by the authors, which consists of four blocks; the main conclusions on the blocks are formed. According to the composite index for the period 20152021, the leading positions are occupied by the Krasnoyarsk Krai, the Arkhangelsk Oblast and the Komi Republic, and the Republics of Karelia, Sakha (Yakutia) and Komi in terms of the index growth rate. The study of the state, dynamics and level of innovation development in the regions of the AZRF shows that some components of innovation potential are unevenly developed in the regions that are fully or partially included in the AZRF. At the same time, the regions differ in the dynamics of innovative development. Thus, the worst indicators of innovative development in accordance with the proposed methodology are observed in the Arkhangelsk Oblast, Chukotka and Nenets Autonomous okrugs. The high correlation between the composite index of innovative development and indicators of socio-economic development of the regions revealed by the authors characterizes the positive impact of innovation activity on the socio-economic development of the AZRF subjects. In this regard, the key recommendations are the following: improvement of legislative support for the formation of eco-industrial, tourist zones, innovation sites and cluster formations in the Arctic territory within the framework of testing new formats of economic intensification of the Russian Arctic regions; formation of a macro-regional register of suppliers of innovative products for the projects of residents of the AZRF with the distribution of preferential measures of a special economic and administrative regime. The prospects of the research are related to the study of critical vulnerabilities in the production and technological processes of the sectors of specialization of the Arctic regions in import substitution.

Формирование арктического этнохозяйственного кластера как условие устойчивого (эколого- и этносохраняющего) развития региона (на примере арктических территорий Красноярского края)

The paper considers the issues of ethno-demographic development and settlement of small-numbered indigenous peoples of the Arctic zone of the Russian Federation in the period between the 2002 and 2020 population censuses. The article analyzes the current state and development of the ethno-economic areas of the Arctic zone of the Krasnoyarsk Krai, assesses the potential for the development of traditional economic activity of indigenous peoples and identifies hindering factors. It is shown that the key mechanism for achieving the goals of sustainable development of traditional economic activities in the Arctic region is an active balanced cluster approach adapted to the specifics of ethno-economic habitats of indigenous minorities of the Arctic. The prerequisites and prospects for creating an ethno-economic cluster in the Arctic zone of Krasnoyarsk Krai are assessed. Promising areas of investment development of socio-economic potential and cooperative relations of traditional economic activities of indigenous minorities are identified. The results of the cluster formation will be increase in the degree of processing and in the output of traditional economic activities, increase in employment and improvement of the standard of living of indigenous small-numbered peoples, transformation of traditional economic activity into a full-fledged sector of the economy of the Arctic zone of the Krasnoyarsk Krai.

The impact of lead, cadmium, and mercury on the reproduction of mountain hares (Lepus timidus L., 1758) in the north of Krasnoyarsk Krai

Reproduction is key to the survival and development of a species. Anthropogenic activities release significant amounts of toxic pollutants into the environment. In this study, we aimed to determine effects of heavy metals on some reproductive parameters of the mountain hare. Female mountain hares (n = 41) were hunted in the reference and industrially polluted areas of Krasnoyarsk Krai during four seasons. Their skeletal muscles, liver, and kidneys were subjected to atomic absorption spectrometry to determine concentrations of lead, cadmium, and mercury. The contents of lead, cadmium, and mercury were significantly higher in the hares from the contaminated areas compared to the reference sites. According to the results, the exposure to lead, cadmium, and mercury had an impact on the reproductive potential of the female mountain hares. In particular, we established correlations between numbers of embryos and corpora lutea and contents of lead in the kidneys and liver, as well as cadmium in the kidneys. The number of corpora lutea and embryonic losses in the female hares from the contaminated areas were higher than those in the hared from reference areas. However, the numbers of embryos did not differ significantly between the compared areas. Our study showed that about 40% of the liver samples and 100% of the muscle tissue samples obtained from the hares in the impact zone contained high concentrations of lead and cadmium. Therefore, hunting in these industrially polluted areas may pose a toxic hazard to the indigenous peoples living there. Further research is needed to assess potential and actual fertility, offspring survival, and other important parameters of mountain hare populations exposed to different levels of chemical pollution.

Perspective on Artisinal and Small-scale gold Mining: Ecological and Socio-economic Inovation

Global aspirations for stringent mercury regulations have not been translated effectively in Russia, largely due to the emergence of new domestic cinnabar mining ventures. These initiatives have increased locally sourced mercury, reducing its cost and undermining efforts to curtail its use. This study employs Stochastic Multicriteria Acceptability Analysis (SMAA) within an environmental finance framework to rigorously assess the challenges associated with mitigating mercury use in artisanal and small-scale gold mining (ASGM) in Russia. The sampling period for the research spans from June to September 2018 in the Krasnoyarsk Krai area, comprising Yeruda and Chebyzhek villages in the Kurakhinsky district and Abalatskoye village in the Minusinsky district. The paper investigated these complexities using SMAA to identify the multifaceted challenges in implementing the Minamata Agreement, a global treaty committed to regulating and curtailing mercury use. The findings revealed that mercury management is associated with various socioeconomic factors, labor relations, and power structures that have collectively hindered mercury-free practices in gold mining. Therefore, this study highlighted the critical need for a holistic, sustainable economic framework by incorporating new insights into the societal metabolic functions of dynamic mineral finance. Utilizing SMAA within the specific context of native employment conditions, the authors challenged the prevailing norms and offered robust, data-driven strategies aimed at reducing or eliminating mercury usage in ASGM.

«Печально зимой в Булуне»: А. В. Боголепов о повседневности заполярной Якутии в 1913–1916 гг.

Goals. The article introduces an unknown manuscript by A. Bogolepov titled ‘Bulun Village of Verkhoyansk District (Yakutsk Oblast)’ and compiled during an exile to the isolated Arctic locality of Yakutia. The narrative was written before the revolutionary events of 1917 and is of certain interest since it lacks any political bias, being characterized by restrained neutrality and sufficient depth of observations over everyday realias of the small northern settlement. A. Bogolepov’s text is attractive for the breadth of issues covered, its consonance with the social and cultural problems faced by the era and discussed by the advanced public. So, it seems reasonable enough to publish the identified document for further discussion in an interdisciplinary perspective. Materials and methods. The manuscript was discovered at the State Archive of Irkutsk Oblast (Coll. 293 ‘East Siberian Department of the Russian Geographical Society’). Furthermore, in search of additional data on the former’s author we investigated the State Archive of Altai Krai (Barnaul), State Archive of Krasnoyarsk Krai (Krasnoyarsk), National Archive of Sakha-Yakutia (Yakutsk), Archive of the Russian Academy of Sciences (Moscow) and its St. Petersburg Branch, and the efforts have yielded a variety of precious finds. The methodological basis rests on the principles characteristic of the field the researchers are actually engaged in — cryoanthropology. Results. The discovered materials open a previously unknown page in the Yakut pre-Soviet Northern studies. A. Bogolepov’s manuscript is rich in data on natural conditions, economic and cultural activities in the small remote settlement somewhat representing the polar world in miniature. The author highlights the interpenetration of Russian and Yakut cultures, mentions some specific local sociocultural phenomena resulting from the geographical location and climatic features. The long cold period — as is stressed by A. Bogolepov — shapes the entire life cycle of the settlement: it completely determines the functioning of the transport network, household and trade agendas, everyday life and leisure pursuits of locals. The isolation and scarcity of social activity, temporal and event-based ‘frozen’ everyday life of the northern society are emphasized. The manuscript is an important source for the research of cryoanthropology, and also contains valuable information on Yakutia’s socioeconomic and cultural history throughout the early decades of the twentieth century.

Роль имперских органов власти в процессе выборов мусульманского духовенства в общинах Енисейской губернии во второй половине XIX – начале XX в.

Introduction. The article discusses some actual conditions experienced by Muslim clerics of Yenisei Governorate (Eastern Siberia) in the context of Imperial Russia’s religious policies throughout the mid-nineteenth to early twentieth centuries. Attention is drawn to that the mid-to-late nineteenth century witnessed a Muslim population increase across the region, which implied that increased spiritual needs be duly satisfied. Goals. The article aims at specifying the role of official authorities in electing Muslim clerics within Yenisei Governorate. Materials and methods. The study focuses on corresponding imperially approved regulations for Muslim clergy and archival materials housed at the State Archive of Krasnoyarsk Krai, Central State Historical Archive of Bashkortostan, and Russian State Historical Archive. It is noteworthy that quite a number of the archival materials are being newly introduced into scientific circulation. The work rests on the methodological principles of objectivity and historicism that prove instrumental in assessing the government’s role in shaping the institution of Muslim clergy in Yenisei Governorate. To accomplish this, the chronological and historic-genetic methods are used. Results. The region’s sociohistorical agenda made any elections of required clerics somewhat problematic. The imperial statutes banned exiled (relocated) believers from participating in such processes, but sometimes legally capable members of a community were even fewer that the former. The obtained status of a mediator between the mahalla and government agencies would, inter alia, give rise to internal controversies. However, believers tended to perceive their mullah as a defender of their interests even at the government level. Our insights into archival materials attest to governorate-level executives had no clear understanding of how to arrange elections of Muslim clerics. Virtually being a government-sanctioned body, Orenburg Mohammedan Assembly would take pains to guarantee trustworthiness of to be appointed candidates. In the early twentieth century, such applicants would face even more restrictions enshrined by regulations and procedures of the Ministry of Internal Affairs.

Maps of Soil Organic Carbon Sequestration Potential in the Russian Croplands

Adoption of the farming systems that aim to sequester carbon in agricultural soils is one of the ways to mitigate global climate change. This study focuses on the estimation of organic carbon sequestration potential of the Russian croplands in the upper (0–30 cm) soil layer by creating a set of maps using the data from global and national databases as the input data. The maps are generated within the FAO Global Soil Organic Carbon Sequestration Potential Map (GSOCseq) project according to the unified methodology using the RothC model to predict the rate of carbon sequestration in 2020–2040 under a business as usual scenario (BAU), as well as under sustainable soil management scenarios with additional different C input (+5, +10, and +20%) resulting from the use of sustainable soil management (SSM) scenarios. The total potential sequestration rate by the croplands of the Russian Federation in the 0–30-cm layer under a BAU scenario is assessed at 8.5 Mt/year and the estimate under SSM scenarios, up to 25.5 Mt/year. The carbon sequestration by the cropland of each soil ecological zone (except for the light chestnut (Eutric Cambisols (Protocalcic)) and brown semidesert (Luvic Calcisols) soils, where it is around zero) and on a national scale is positive. The Altai krai, Omsk oblast, Novosibirsk oblast, and Krasnoyarsk krai have the greatest potential for sequestration. Several subjects of the Russian Federation—Krasnodar krai, Republic of Crimea, Rostov oblast, Primorskii krai, Republic of Adygea, and Kaliningrad oblast—demand the adoption of sustainable management of soil resources.

Forecasting Dendrolimus sibiricus Outbreaks: Data Analysis and Genetic Programming-Based Predictive Modeling

This study presents an approach to forecast outbreaks of Dendrolimus sibiricus, a significant pest affecting taiga ecosystems. Leveraging comprehensive datasets encompassing climatic variables and forest attributes from 15,000 taiga parcels in the Krasnoyarsk Krai region, we employ genetic programming-based predictive modeling. Our methodology utilizes Random Forest algorithm to develop robust forecasting model through integrated data analysis techniques. By optimizing hyperparameters within the predictive model, we achieved heightened accuracy, reaching a maximum precision of 0.9941 in forecasting pest outbreaks up to one year in advance.

Sociological analysis of the functioning of early assistance services for children under 3 years in the Krasnoyarsk Krai

The purpose of the study is a comprehensive sociological analysis of the functioning of early intervention services for children under 3 years of age in the Krasnoyarsk Territory. The tasks of the analysis include: 1) studying the structure of the early intervention service as a social organization, the functions of its elements, systemic connections and relationships between them; 2) studying the satisfaction of representatives of client families with the work of early intervention services; 3) studying the subjective perceptions of employees of early intervention services and representative’s client families about the content and meaning of the services. The authors used the methods of a sociological survey, in-depth interviews, participant observation. Based on a number of indicators, the authors concluded that early intervention services were predominantly highly effective. The article shows the problem area of the functioning of early intervention services, which lies in the difference in understanding the goals and results of working with children on the part of client families and early intervention service specialists. Specialists see as the main goal the development of functional skills by children that contribute to socialization and independence, and then the improvement, the acquisition of educational, cognitive skills. Parents often prioritize learning skills when setting class goals. This difference may reduce parental satisfaction with the results of early intervention and the effectiveness of classes. The authors revealed the dependence of the level of involvement of parents in work with children together with specialists from early intervention services on the length of service and the age of the child. The more experience and the older the child, the less parents are involved in working with children. The authors proposed a social typology of representatives of client families on the grounds of their involvement in work with children and their attitude to the results of work with a child.

Inflation on agricultural products and food stuff as a threat to food security (Based on the materials of the Siberian Federal District and the Krasnoyarsk Krai)

Subject. The article addresses the issues of economic availability of food for the population. Objectives. The purpose is to develop measures to minimize negative effects of inflation and ensure sustainable access of the population to high-quality and affordable food products. Methods. The study employs methods of statistical analysis. Results. Measures to increase the affordability of food should include: regulating food prices and targeting food inflation, ensuring outstripping or commensurate with the rate of inflation growth of incomes of the population, improving the quality and accessibility of food stuff for low-income citizens. Conclusions. Despite the growth of incomes of the population, food inflationary dynamics reduces the level of economic affordability of food products in the Siberian Federal District as a whole and in certain regions of Russia.

Variability of Genetic Diversity of Spring Barley by Hordein-Coding Locus over a 40-Year Period of Scientific Breeding in Krasnoyarsk Krai
