PREVALENCE OF INJURIES AMONG WASTE PICKERS. A CASE STUDY IN NIGERIA
Authors: Ali Ahmed Fate , Yusuf Farouk Idi
Published: December 2021

Waste picking might provide, in low-income countries, a livelihood for many individuals representing an important survival strategy. However, during their activities, waste pickers are at risk of encountering harmful waste, which could cause injuries and other infectious diseases. This paper investigates the occurrences of injury among waste pickers and the methods they use to treat the injuries in Bauchi city, Northeastern Nigeria. A total of 322 waste pickers were randomly selected across 80 waste pickers’ middlemen shops. Data was obtained through questionnaire and interview. Based on the data presented, 1474 frequencies of injuries were reported among 247 waste pickers. Age, education and working experience are significant parameters to the prevalence of injuries among waste pickers, and the incidence of injuries increased with the decrease in those parameters. The study shows that most of the waste pickers experienced injuries, most of whom do not attend clinic when injury occurs; instead, they used salt, ash, sand, hydraulic, kerosene, battery acid, among others, to treat their wounds. Cuts and pierces are good entry points for bacteria and viruses, which can eventually spread to the general public infectious diseases, such as Hepatitis, Cholera and Lassa fever. Provision of Personal Protection Equipment (PPE), a labor rights policy, immunization and the launch of an awareness campaign are among the recommendations made by this study.

Un mundo de músicas instrumentales. Aproximaciones sobre escenas de jazz-rock de la ciudad de Córdoba entre 1978/1997
Authors: Bruno María Sol
Published: December 2021

En este artículo indagamos una escena musical de la ciudad de Córdoba donde las producciones eran mayormente instrumentales, y pertenecieron a un género musical que fusionaba el rock y el jazz. Nos preguntamos por las formas y características que tomaron aquellas poéticas a partir de la trayectoria de dos conjuntos musicales integrados por artistas en común: el grupo Encuentro (1978/1982) y Los Músicos del Centro (1982/1997). Este texto, como señala el título, es una aproximación empírica, que carece de antecedentes locales que remitan específicamente al género del jazz o a los conjuntos abordados. El trabajo se estructura a través de tres ejes centrales. Para empezar, realizamos una breve presentación de los artistas, elementos distintivos de sus trayectorias, consumos culturales y formación musical. Posteriormente analizamos las producciones sonoras que se materializaron en discos de los dos grupos musicales. Por último, ahondamos sobre los sistemas de distribución y formas de financiamiento de las obras de arte.
Lo etnográfico y la génesis de una matriz disciplinaria en la antropología social argentina
Authors: Visacovsky Sergio
Published: December 2021

En este artículo trato el desarrollo de la antropología en la Argentina desde el retorno democrático a inicios de la década de 1980 hasta los inicios del corriente siglo. Mi pretensión es analizar cómo lo etnográfico llegó a ser una matriz disciplinaria. Como mostraré, lo etnográfico devino en el modo aceptado y normal de producción de conocimiento antropológico en la Argentina en los albores del presente siglo. Por un lado, centro mi atención en la enseñanza universitaria de la investigación en antropología y el liderazgo de figuras claves, como Rosana Guber. Por otro, muestro la influencia crucial de la antropología brasileña para la transformación de la matriz disciplinar, lo cual permitió la recuperación y legitimación de desarrollos locales precedentes. Finalmente, destaco la importancia de los posgrados para la cristalización de los proyectos disciplinares centrados en lo etnográfico, los cuales rompieron el monopolio de las definiciones legítimas que conservaban las carreras de antropología.
A formação do leitor no Ensino Médio: Competências e habilidades no ensino da Literatura Machadiana
Authors: Carvalho dos Reis Luciana
Published: December 2021

À luz de estudiosos acerca da leitura e da escrita como Emília Ferreiro e Ana Teberosky, e de críticos e ensaístas voltados para a análise das obras machadianas, a proposta apresentada nesta dissertação visou observar os aspectos que emanam o desinteresse dos alunos do Ensino Médio pela Literatura Clássica Brasileira, em especial a Literatura do escritor Machado de Assis. A pesquisa buscou comparar a presença do escritor no livro didático com os estudos acadêmicos mais recentes a seu respeito. Acreditou-se haver um descompasso entre esse Machado entrevisto na crítica e aquele no livro didático, implicando uma simplificação que não faria jus ao autor. Para fins desses apontamentos, elegeu-se como objeto de análise o livro didático: Português: Linguagens, volume 2, de William Roberto Cereja e Thereza Cochar Magalhães. Este foi selecionado e bem avaliado pelo Programa Nacional do Livro para o Ensino Médio (PNLEM), na edição de 2015, para o ano letivo de 2016. No entanto, trazer à baila o desinteresse pela Literatura Clássica no circuito das escolas públicas estaduais nesta pesquisa não quer pressupor a “demonização” do livro didático, mas rever a prática adotada no processo de ensino-aprendizagem. Para isso buscou-se estudar os fatores que contribuem para o desenvolvimento de competências e habilidades na formação de leitores da Literatura de Machado de Assis na escola estadual de Ensino Médio Emílio Nemer. e para se chegar a esse objetivo, procurou-se analisar os meandros textuais e estruturais das obras do escritor Machado de Assis e a concepção da crítica e do livro didático; analisou-se o PCNEM no que diz respeito a Literatura; examinou e refletiu-se sobre a prática pedagógica desenvolvida para o processo ensino-aprendizagem; elaborou e aplicou-se um questionário para os alunos sobre o hábito de leitura; estudou-se práticas alternativas para despertar nos alunos o gosto pela Literatura; elaborou e aplicou-se um questionário para os pedagogos e professores sobre o hábito de leitura. Para isso, na primeira etapa, houve a discussão e viabilidade do projeto de pesquisa; na segunda etapa, houve o levantamento bibliográfico para dar suporte à pesquisa, na terceira etapa, houve a construção da fundamentação teórico-conceitual e aplicação dos questionários abertos e fechados e a quarta etapa a discussão dos dados obtidos na pesquisa. O resultado é uma emocionante pesquisa ação de cunho analítico exploratório voltada para o aprofundamento do estudo do tema: Leitura e escrita.

Authors:   CHE, Kazan, Russia, Badamshina G.G. ,   KSMU, Kazan, Russia, Sizova E.P. , Fatkhutdinova L.M.
Published: December 2021

Abstract: Introduction. In the course of their work, medical workers are exposed to a biological factor, including bacterial, viral nature. Medical personnel come into contact with patients with measles, rubella, diphtheria, tuberculosis, hepatitis, coronavirus infection and other infectious diseases. The aim of the study is to assess the humoral immunity by the presence antibodies to the measles, rubella, hepatitis B viruses, to the causative agent COVID-19, tuberculosis and diphtheria bacteria in health care workers. Methods. Antibodies to measles, rubella, hepatitis B viruses, diphtheria and tetanus pathogens were measured in blood serum samples of 1221 MW; total antibodies to mycobacterium tuberculosis - in 120 MW; antibodies to the nucleocapsid protein of the SARS-CoV-2 virus – in 301 MW. The study was carried out by the method of enzyme immunoassay using commercial test systems; antibodies to diphtheria toxoid were detected in the passive hemagglutination reaction. The control group consisted of persons of engineering and technical personnel, comparable in age, gender and work experience. Results. Medical personnel were found to have significantly more frequent detection of seronegative reactions to the presence of antibodies to the hepatitis B virus (40.9% and 13.5%, p<0.001) of measles (28.8% and 3.9%, p<0.05); significantly high prevalence in the presence of total antibodies to mycobacterium tuberculosis (7.5% of cases in medical, 0% of cases of workers in the control group, p<0.05). In comparison with doctors, nurses had a significantly higher prevalence of antibodies to the nucleocapsid of the SARS-CoV-2 virus (38.9% and 23.7%, p<0.05). Conclusions. The study of post-vaccination immunity in medical workers showed the presence of a high proportion of seronegative individuals among vaccinated (viral hepatitis B, measles) medical workers and, accordingly, significant biological risks. A higher seroprevalence in total antibodies to Mycobacterium tuberculosis may also indicate insufficient immune protection among MW. The biological significance of seroprevalence to SARS-CoV-2 virus proteins (for nurses) requires further study.

Abstract: Introduction. Air pollution with particulate matter (PM) is a serious global problem. In the Russian Federation, regular field measurements of PMs in the ambient air are carried out only in a number of cities, and the data, as a rule, are not systematized. Aim of the study: retrospective analysis of the data set on concentrations of fine particles in the ambient air of the city of Kazan. Methods. Retrospective analysis of pollution by fine fractions of suspended solids in the ambient air of Kazan in the period from 2016 to 2020 has been carried out. To study the effect of individual factors (time period (year), measurement time during the day, climatic conditions, the presence of other pollutants) on the pollution levels PM 10 and PM 2.5, regression analysis was applied based on the method of mixed models. Results. The PM 10 concentrations remained stable over a 5-year period, while the PM 2.5 concentrations decreased. At the same time, an increase in the maximum annual concentrations of both fractions was observed. The concentrations of PM 10 and PM 2.5 significantly depended on weather factors. The presence of nitrogen oxides and organic carbon in the ambient air was associated with significantly higher concentrations of PM 10 and PM 2.5. Conclusion. A statistically significant upward trend in the dynamics of the years of the maximum annual values for both fractions of suspended particles can increase health risks. Secondary pollutants (nitrogen oxides, organic carbon) is an important factor for the formation of secondary particles in the ambient air. Implementation of preventive measures in relation to industrial emissions, regional urban planning policy and a scientifically based program of social and hygienic monitoring are the most important tools for effective management of health risks caused by exposure to fine particles.

[ALLELOCHEMICAL POTENTIAL OF AQUEOUS EXTRACT AND MULCH OF PLANT BIOMASS OF SORGHUM (Sorgum bicolor L. Moench)]. This study was aimed to examine the allelopathic potential of sorghum through aqueous extract and mulch from biomass on seed germination and early growth of three tested plants, namely rice, mustard and cucumber. The results showed that the aqueous extract of the sorghum biomass significantly inhibited the germination of mustard and cucumber seeds, reduced the vigor-index of the germination of rice, mustard and cucumber seeds, and suppressed the growth of radicle length of mustard sprouts. The same thing was seen when sorghum biomass was tested as mulch which also suppressed the early growth of the tested plants on the variables of stem height, fresh and dry weight of biomass of rice, mustard and cucumber. The higher the concentration of allelochemicals extract or sorghum mulch, the stronger the inhibition on germination and early growth of the three test plants. At a concentration of 10% allelochemicals suppressed the germination of mustard and cucumber to 76 and 79%, respectively, while a dose of 10% mulch suppressed early growth in the height of rice, mustard, and cucumber to 56, 55, and 68%; and dry weight to 53, 30 and 60%. The results of this study are important information about the allelochemical potential of sorghum as a natural herbicide in integrated weed management

Authors: Pokhrel Laxman
Published: December 2021

Background: Social Media has become a prevalent platform for students to receive information content such as admission notices, holiday notices from business schools. Students are communicating, collaborating, and resource sharing by several social media in the names of support groups.

Objective: The purpose of the research paper is to examine social media adoption intention among undergraduate students of business schools in Kathmandu Valley in 2020.

Method: The data were collected with the self-administered questionnaires from 200 undergraduate students. Partial Least Square (PLS) - SEM was applied to test the direct and mediated effect of the proposed hypotheses.

Result: The results revealed that perceived ease of use, perceived usefulness, collaboration, resource sharing, communication and intention of social mediation adoption. Perceived ease of use partially mediates the relationship between communications, resource sharing on the intention of social media adoption.

Conclusion: The study concludes that undergraduate level students of business schools could intent to social media when they find the social media useful, easy to use, collaborative, communication, and resource sharing among students. Moreover, students could intend to use social media when they perceived ease of social media use over communication, resource sharing for educational purposes. The conclusion could provide information for business schools in creating an atmosphere of collaboration, communication, and resource sharing to increase engagement in social media.

Originality: Social media adoption in the Nepali context is a relatively less explored phenomenon. This research established that social media adoption is impacted by collaborative learning, resource sharing, perceived usefulness, and communication.

Authors: Bhagat Meghna , Joy Rosewine
Published: December 2021

Background: Progressive degradation of the environment due to the intervention of humans in the natural processes brought into light the need and the concept of sustainable development. The three pillars of sustainable development are Economic, Social, and Environmental. Sustainability has become one of the important tools to overcome the threats and is the dire need of the hour. This paper illustrates the detailed concept of Space-based solar power (SBSP) which defines the collection of solar energy in outer space and directing it towards the earth using electromagnetic waves. The edge of collecting solar power from space and not by the conventional methods include the strong collection rate and improved collection period. This is mainly because of the absence of the earth’s atmosphere that consists of a lot of external impurities and the decreased effects of reflection and absorption on solar energy on its way to earth.
Objective: To put forward the importance of the use of space-based solar power system in India and to establish how space-based solar power is one of the answers of sustainable energy development for a better future for the country.
Method: The study is based on secondary data. The findings indicate the need for sustainable energy development and the effective use of space-based solar power which would answer to the never-ending demands of human beings.
Result: The article also delineates the opportunities of space-based solar power as well as the challenges that might be faced while building the system.
Conclusion: The paper is a descriptive and conceptual study which illustrates SBSP as an innovative and important breakthrough in the field of science and one of the most important topics of discussion that needs to be addressed. The paper suggests the need for conducting more study on the topic and development of projects to measure its feasibility in the future, in terms of Indian context.
A Slap in the Face of Socialist Taste: The Novel "Nikolai Nikolaevich" by Yuz Aleshkovsky As a Contestation of the Rules of Socialist Realism
Authors: Tyszkowska-Kasprzak Elżbieta
Published: December 2021

Yuz Aleshkovsky wrote the novel „Nikolai Nikolaevich” in the 1970s. For a long time, the work was disseminated in samizdat and it appeared in print for the first time only in 1980. Composed under the censorship conditions of socialist realism dominant in the arts, this work violates strict taboos imposed on subjects related to sexuality and stylistic solutions which exclude sub-normative vocabulary. In many aspects, the composition of the novel resembles the pattern of the production novel. At the same time, the writer negate the values propagated in the art of socialist realism: the main character is a former pickpocket, who built a comfortable life for himself as a sperm donor in a laboratory and talks about his professional achievements in a language saturated with profanity and elements of criminal jargon. The plot of the work is based on an amalgamation of components characteristic of ideologized literary texts with elements that were unacceptable in such texts. The introduction into the novel of the theme of corporality, and human sexuality, which was a taboo topic in socialist realist literature, introduces a major dissonance and induces produces a comic effect.
Zapiski diarystyczne Poliny Żerebcowej jako forma protestu
Authors: Pawletko Beata
Published: December 2021

Artykuł to próba analizy działalności twórczej oraz społeczno-politycznej Poliny Żerebcowej jako formy protestu. W powstającym dekadę diariuszu możemy zaobserwować przyspieszone dojrzewanie jego autorki (pierwsze zapiski, rysunki, wiersze tworzy niespełna dziewięcioletnia dziewczynka, ostatnie pisze dziewiętnastolatka). Wraz z przyspieszonym dojrzewaniem wymuszonym przez okoliczności wojenne w diariuszu możemy zaobserwować zmieniającą się perspektywę oglądu rzeczywistości. Diarystka wciąż skupia uwagę na problemach osobistych, przede wszystkim przybierającym na sile konflikcie z matką, u której coraz częściej dają o sobie znać symptomy stresu pourazowego, co przekłada się na wrogość wobec córki i zapisków jej autorstwa, skutkując przemocą słowną i fizyczną, a także szantażem emocjonalnym. Z czasem dziennik Żerebcowej staje się coraz wyraźniej aktem oskarżenia wobec stron konfliktu rosyjsko-czeczeńskiego, zawierającym niewygodne dla wielu ludzi szczegóły potwierdzające, że z republiki, w której przed wojną w pokojowej atmosferze żyli przedstawiciele różnych narodów i wyznań, Czeczenia stała się areną barbarzyńskich aktów terroru, nienawiści, gwałtów, tortur, korupcji i patologizacji życia, zdziczenia obyczajów i norm. Diarystka potwierdza, że największymi ofiarami konfliktu są cywilni mieszkańcy Czeczenii, pozbawieni pomocy materialnej czy duchowego wsparcia, zwracając przy okazji uwagę na koszmar życia uchodźców, często okaleczonych fizycznie i psychicznie, którzy samotnie i często bezskutecznie walczą o prawo do odszkodowań i godnego życia w powojennej rzeczywistości.

Scientific data on distribution and abundance of endangered species are the foundation for their effective conservation and management. In this paper, we present results of the first scientifically – based estimation of lynx population size in Croatia. The goal of the study was to determine the area of lynx distribution and to estimate the minimum size of lynx population in Croatia in the period 2018 - 2020. To determine lynx distribution, 902 signs of lynx presence were collected in the period from the beginning of May 2018 until the end of April 2020. Out of those, 92.8% of lynx observations were categorized as C1, 2.8% as C2 and 4.4% as C3. Permanent lynx presence was confirmed in Primorsko – Goranska and Ličko – Senjska county, in southern part of Karlovac county and north-eastern part of Zadar county on the total surface of 7200 km2. For the minimum population size estimation, 804 camera trap photographs led to identification of 89 – 108 adult lynxes. Among 108 identified individuals there were 29 females, 22 males, while for 7 animals the sex was not determined. During the two reproductive seasons, we photographed 44 cubs in 25 litters. Future important steps in lynx population monitoring are correcting the deficiencies identified in this study and implementation of methodology that will allow us to use spatial capture recapture models for estimation of lynx abundance in Croatia.

Although sessile oak is one of the most important deciduous forest tree species in Europe, data on the diversity of ectomycorrhizal (ECM) fungi on sessile oaks in the Republic of Serbia are scarce. The aim of this study was to provide the first insight into the diversity of ECM fungi on sessile oak in Serbia. Two sites Info center and Brankovac, located in National Park Fruška gora were chosen. ECM fungi were identified combining morphological and anatomical characterization with molecular analysis of nuclear rDNA internal transcribed spacer (ITS) region. All vital ECM root tips were counted, diversity indices were calculated, and ECM fungi were classified into the exploration types. The granulometric and chemical composition of soil were analyzed as well. At both sites, 26 different ECM fungal taxa were recorded in total, 17 taxa were observed at the site Info center and 12 taxa at Brankovac. ECM communities consisted of a few abundant taxa and a larger number of rare taxa. Lactarius quietus, Cenococcum geophilum, and Tomentella sublilacina were recorded at both sites. High abundance of contact and short-distance exploration types recorded in studied stands suggests that soils are sufficiently rich in total nitrogen and organic matter. Values of diversity indices recorded in studied sessile oak stands from Fruška gora were lower in comparison to those obtained in stands of different oak species across Europe which is likely induced by drought. To get a more thorough insight into the diversity of ECM fungi on sessile oak, research should be continued at more sites and seasonal dynamics should be included.

Published: December 2021

The analysis of data from the first two decades of the 21st century shows that the area under forests in Bosnia and Herzegovina is gradually decreasing. In order to gain a detailed insight into this process, the paper will analyse the forest databases of the European satellite monitoring program Copernicus. This program, among other things, monitors the condition of forests in 39 European countries by using the High Resolution Layer (HRL). The HRL Forests database consists of 3 types of (status) products, and additional change products. The status products are available for the reference years 2012, 2015, and 2018. The status layers provide information on the Dominant Leaf Type and the Tree Cover Density at pixel level for the reference year 2018 in 10 m resolution. The Forest Type layer largely follows the Food and Agriculture Organization (FAO) forest definition.
Also, the paper will use the data on forests from the CORINE Land Cover project for 2000, 2006, 2012 and 2018. The time-series includes a land change layer, highlighting changes in land cover and land use. The CLC Changes database will be analysed separately for three periods: 2000-2006, 2006-2012 and 2012-2018, due to more accurate data on forest losses.
The results of the research show that forests in Bosnia and Herzegovina were reduced by 2.95%, in the period 2012-2018, where 2.55% of them were coniferous. Forests are primarily endangered by the process of conversion to transitional forest / shrub and fires.
Partner supportive dyadic coping and relationship stability among parents of children with autism spectrum disorder
Authors: Löw Ajana
Published: December 2021

Studies involving parents of children with autism spectrum disorder (ASD) have reported negative relationship outcomes for some couples and positive for others, indicating the need to determine the moderators of the link between stress and divorce. This study aims to examine the moderating effect of partner supportive dyadic coping, i.e., interpersonal coping that involves providing comfort, empathy, or practical advice to one’s partner, on the association between parental stress and relationship stability among parents of children with ASD. The study was conducted on a sample of parents (N=89) who met the criteria of being in a relationship and parenting at least one child diagnosed with ASD. The questionnaire included the Parental Stress Scale, a subscale of the Dyadic Coping Inventory, an item assessing the potential for divorce, and sociodemographic variables. The logistic regression analysis model explained a substantial amount of the variance of relationship stability. Higher probability of having a stable relationship was associated with lower levels of parental stress and higher levels of supportive dyadic coping. Additionally, supportive dyadic coping buffered the negative effect of parental stress: the effect of stress on relationship stability was evident only among participants whose partners showed low supportive dyadic coping. The results indicate that a relationship does not necessarily end in divorce when a couple experiences stressful circumstances, such as raising a child with ASD. The key factor could be supportive dyadic coping that prevents negative effects of stress on relationship maintenance. Support services should aim to enhance supportive dyadic coping skills among parents, and advocate for the fact that both stress and coping are joint processes of partners in a relationship.
Pojavnost problema u ponašanju djece u ustanovama ranog i predškolskog odgoja i obrazovanja

Published: December 2021

Problemi u ponašanju djece rane i predškolske dobi povezani su s kasnijom socijalizacijom, prilagodbom na školu, školskim uspjehom i drugim obrazovnim postignućima u adolescentskoj i odrasloj dobi, što ukazuje na važnost pravovremenog prepoznavanja odstupanja od uobičajenog psihosocijalnog funkcioniranja i ponašanja djece. Poznato je da je za prevenciju nepovoljnih razvojnih ishoda, uključujući razvoj problema u ponašanju, ključno razdoblje do šeste godine djetetova života. Cilj je ovog istraživanja analizirati pojavnost problema u ponašanju djece rane i predškolske dobi u Republici Hrvatskoj s obzirom na spol i razvojni status djece, na temelju procjena roditelja i odgojitelja. Procijenjeno je ponašanje 447 djece u dobi od pet i šest godina u 10 hrvatskih programa ranog i predškolskog odgoja i obrazovanja. Utvrđeno je da s učestalošću manifestiranja problema u ponašanju opada njihov udio u populaciji te da izražajnije probleme u ponašanju prema procjenama odgojitelja manifestira 7%, a prema procjenama roditelja 9% djece rane i predškolske dobi. Na uzorku ovog istraživanja nisu utvrđene razlike u procjenama učestalosti manifestiranja internaliziranih problema u ponašanju između dječaka i djevojčica, ali se pokazalo da odgojitelji i roditelji češće procjenjuju prisutnost eksternaliziranih problema u ponašanju kod dječaka u odnosu na djevojčice. Odgojitelji i roditelji procjenjuju da djeca s teškoćama u razvoju u odnosu na djecu tipičnog razvoja češće manifestiraju internalizirane probleme u ponašanju, dok razlike u procjenama učestalosti manifestiranja eksternaliziranih problema s obzirom na razvojni status djece nisu utvrđene. Ovim istraživanjem potvrđuju se mogućnosti ranog prepoznavanja problema u ponašanju djece i ukazuje se na relevantnost i povezanost procjena ponašanja djece od strane njihovih roditelja i odgojitelja.

Udomiteljstvo se definira kao oblik pružanja socijalne usluge smještaja djetetu ili odrasloj osobi, koju pruža udomitelj sa svojom obitelji ili udomitelj koji živi sam, pod određenim uvjetima. U radu je prikazano udomiteljstvo za osobe starije životne dobi kroz teorijsku i istraživačku prizmu te udomiteljstvo u kontekstu procesa deinstitucionalizacije. Svrha je udomiteljstva osiguravanje skrbi i potpore korisniku u poticajnom i pozitivnom obiteljskom okruženju u skladu s njegovim individualnim planom promjene. Iako se posljednjih godina uočava porast broja osoba starije životne dobi smještenih u udomiteljske obitelji u Hrvatskoj, izostalo je zanimanje i kritički osvrt znanstvene zajednice za ovaj oblik
skrbi. Stoga je svrha rada opisati udomiteljstvo za osobe starije životne dobi u RH s ciljem unapređenja ovog oblika
skrbi.

Correlation between quantitative traits that affect grain yield of maize hybrids
Authors: Krivosheev G. Ya. , Ignatiev A. S.
Published: December 2021

The selection of pairs for hybridization requires knowledge about the correlation of the most important quantitative traits that affect grain yield of maize hybrids. The current study was carried out in the Agricultural Research Center “Donskoy” located in the south of the Rostov region with unstable moisture. The years of study (2018–2020) were arid (HThC 0.32–0.89). The purpose of the current study was to evaluate the correlation between quantitative traits and their influence on grain yield of maize hybrids under arid conditions. The objects of research were 96 interline maize hybrids. The analysis has identified the correlation between grain yield and such quantitative traits as ‘one maize ear weight’ (r = 0.64...0.87), ‘number of grains per one maize ear row’ (r = 0.37...0.75), ‘number of grains per maize ear’ (r = 0.32...0.51), ‘number of maize ears per plant’ (r = 0.41...0.53), ‘grain yield’ (r = 0.45...0.64). The traits ‘1000-grain weight’ and ‘number of grain rows’ had either no or slight effect on the formation of grain yield of maize hybrids (r = -0.12...0.28). There have been established the traits, the high values of which were well-combining in one genotype. The values of the trait ‘one maize ear weight’ raised due to an increase of the trait ‘number of grains per one maize ear row’ (r = 0.27...0.74), ‘number of grains per maize ear’ (r = 0.26...0.55), ‘grain yield’ (r = 0.21...0.52). The trait ‘number of grains per maize ear’ raised with an increase in the values of such constituent components as ‘number of grains per one maize ear row’ (r = 0.70...0.76), ‘number of grain rows per maize ear’ (r = 0.59...0.66), and also with an increase of ‘number of maize ears per plant’ (r = 0.32...0.51) and ‘grain yield’ (r = 0.36...0.38). There have been identified difficulty-combining quantitative traits, when the value of the trait ‘1000-grain weight’ decreased with the increase of the ‘number of grain rows per maize ear’ (r = – 0.18...-0.56), ‘number of grains per a maize ear row’ (r = -0.15...-0.31) and ‘grain yield’ (r = -0.01...-0.36).

The current paper has presented the characteristics of the new winter bread wheat varieties of unified type developed by the FSBSI Agricultural Research Center “Donskoy”. Winter wheat is the most valuable grain food crop grown in vast areas. Breeding plays an important role in increasing production volume and improving grain quality as the basis of the country’s food fund. Expanding grain crops area, among which wheat predominates, there is a problem of crop rotation. Therefore, the development of unified varieties capable of producing stable high grain yields after various forecrops is one of the most urgent areas of breeding work for winter bread wheat. The purpose of the current study was to characterize the new winter bread wheat varieties of unified type developed by the FSBSI Agricultural Research Center “Donskoy” according to the main economically valuable traits. Due to the intensive breeding work over the past decade, on the basis of some of the best zoned varieties ‘Ermak’, ‘Stanichnaya’, ‘Donskoy syurpriz’ there was developed a number of new promising genotypes, which are already being used in production sowings of winter wheat in the Rostov region and other regions of our country. The new winter bread wheat varieties of unified type ‘Lydia’, ‘Kapitan’, ‘Lilit’, ‘Krasa Dona’, ‘Volnitsa’, ‘Volny Don’, ‘Zhavoronok’ and ‘Polina’ are more productive than their parental forms. In combination with grain of high quality, resistance to bio and abiotic environmental factors, they are very valuable, beneficial for cultivation and improvement of the production of commercial wheat grain of high quality.
