In eco-friendly farming systems, the biologicals help to increase winter wheat productivity and improve grain quality. These include both stubble biodestructors that accelerate the return of nutrients from by-products to the soil and multifunctional biologicals with fertilising, growth-regulating and protective properties. Purpose. To determine the influence of the stubble biodestructors and multifunctional biologicals under different fertilization backgrounds on the formation of individual plant productivity, yield and grain quality of winter wheat in the conditions of the Right-Bank Forest-Steppe. Methods. Field method was used to study the interaction of the investigated factors on the plant growth and development, as well as and the winter wheat yield; quantitative-weight method – to determine the structure of the yield; mathematical and statistical method – to analyse the reliability of the obtained results. Results. It was established that the application of stubble biodestructors and multifunctional biologicals had an impact on the formation of the winter wheat yield and provided an increase in the number of productive stems by 4–9 %, grain weight per head by 3–7 %, and yield by 8–17 % against the background without fertilizers. The application of N90Р60К60 resulted in an increase in the number of productive stems by 10 %, the grain weight per head by 14 %, and the yield by 31% compared to the background without fertiliser. The use of biological preparations against this background provided an additional increase in productivity in the range of 9–15 %, which was accompanied by an increase in the number of productive stems and the weight of the ear of grain by 3–6 % and 5–8 %, respectively. On this background, the application of biologicals provided an additional increase in yield within 9–15 %, as well as an increase in the number of productive stems and grain weight per head by 3–6 % and 5–8 %, respectively. The highest yield of winter wheat was provided by the combination of the stubble biodestructor Organic-Balance with the of seed and crop treatment with a multifunctional biologicals Organic-Balance on a non-fertilised background – 5.27 t/ha and on a mineral background – 6.79 t/ha due to high productive stem density and the highest grain weight per head. Conclusions. In the Right-Bank Forest-Steppe on the non-fertilised background and mineral background with N90Р60К60, the maximum grain yield of winter wheat grown after sunflower was obtained due to the combination of technological elements, including the application of stubble biodestructors and multifunctional biologicals for seed and crop treatment.

As an important food crop, red lentils account for 70 % of gross consumption, and the demand for these lentils among consumers in Ukraine is constantly increasing, so it is important to develop and promote varieties of this species into production. Purpose. To create and evaluate a new initial material based on a set of economically valuable traits for the red lentil breeding. Methods. The research was conducted at the State Enterprise \"Experimental Farm Krasnohradske\" in the 2020–2022. The main method used for lentil breeding is intraspecific hybridization followed by individual selection in nurseries. Records and observations were carried out according to generally accepted methods. Results. Plant height of the most productive hybrids ranged from 47.0 to 56.5 cm. The coefficient of variation for this indicator was in the range of 6.4–10.8 %. The number of lateral branches in the studied samples was 5-18 pcs, the coefficient of variation ranged from 15.2 to 26.2 %. The highest number of beans per plant was in the following combinations: natural hybrid with CN 111395 – 281 pcs, and CN 111396 × (Stanka 2 × K. 1212) – 261 pcs on average, the coefficient of variation of this trait was within 32-45 %.

In Ukraine, up to 5 million hectares of land were removed from agricultural crop rotation. These lands can be successfully used for bioenergy due to soil recultivation. They are represented by both ordinary soils contaminated with heavy metals and completely degraded alumina with high salinity. Issues. The land improvement aims to obtain biomass for the bioenergy industry, also to restore fertility, improve the ecological condition of the man-made region, and create new jobs. With proper use, considering all the above aspects, soils can gradually return to agricultural crop rota-tion. Aim. To study and select an initial material for the development of high-yield hybrids of sugar sorghum and broom millet for solid fuel production. Materials. Variety testing trials on sugar sorghum was carried out at the Synelnykove Breeding and Research Station, where 59 samples were examined, their yield was 23–79 t/ha. Results. We identified the promising hybrid combinations with the highest yield of green mass: F1 (Nyzkorosle 93s x Karlykove 45) – 79.7 t/ha, and F1 (Dn71s x Karlykove 45) – 73.6 t/ha. The yield of samples F1 (Rannie 776s x Karlykove 45) and F1 (Yefremivske bile 2s x Karlykove 45) was slightly less, and amounted to 67.4 and 67.0 t/ha, respectively.

The economic crisis requires modern winter wheat cultivation technologies based on the principles of financial feasibility, energy saving and environmental safety. Issues. Changes in animal husbandry have led to the differentiation of fodder crops, which are used as predecessors of winter wheat. Now, other types of perennial legume grasses are grown along with its traditional predecessor meadow clover. However, it is necessary to carry out research and calculations due to the lack of results of the ecological, economic and bioenergy feasibility of non-traditional perennial legume grasses as predecessors of winter wheat. Aim. To investigate the indicators of ecological, economic and bioenergy efficiency of winter wheat cultivation after six species of perennial legume grasses as predecessors, such as meadow clover, alfalfa, sand esparcet, white sweet clover, bird's-foot-trefoil, eastern galega, and also after the maize for silage (control). Methods. Field studies with subsequent calculation of economic efficiency of winter wheat cultivation based on technological charts and costs, as well as the energy efficiency of the technologies under study according to the methods of O.K. Medvedovskyi, P.I. Ivanenko and VASKHNIL were conducted. Results. The highest grain yield was 6.52 t/ha when winter wheat was cultivated after maize for silage with high rates of mineral fertilizers and pesticides. When winter wheat was cultivated after perennial legume grasses, the rates of mineral fertilizers and pesticides were significantly lower. Accordingly, the grain yield of winter wheat grown after perennial legume grasses was by 11.1–38.2 % lower than after silage maize, and it was 4.03–5.80 t/ha. The highest grain yield was observed after meadow clover, and the lowest – after bird's-foot-trefoil. The highest level of profitability (90.7 %) is provided by the cultivation of winter wheat after the predecessor meadow clover. When winter wheat was grown after such predecessors as meadow clover, white sweet clover, sand esparcet and eastern galega with limited rates of pesticides and mineral fertilizers, the level of profitability was 5.7–46.8 % higher than indicator for winter wheat after silage maize with high rates of mineral fertilizers and pesticides At the same time, winter wheat profitability after bird's-foot-trefoil and alfalfa equaled to the indicator for silage maize.

The efficiency of the grain production industry allows to provide the population with food and the state with currency. A significant place in the increase in the volume of grain crops is assigned to maize, which is in stable demand both in the domestic and foreign markets. Issues. Due to the lack of programs of grain maize breeding in the Western Forest-Steppe zone, it is necessary to purchase the hybrids and seed material in the originating institutions of the Central Forest-Steppe and Steppe zones. The choice of high-yield hybrids depends on their biological char-acteristics, effective use of soil and climatic conditions and positive response to the cultivation technology. Aim. To conduct a comprehensive and economic evaluation of maize hybrids depend-ing on the implementation of their genetic potential in the soil and climatic conditions of the West-ern Forest-Steppe and their response to the system of basic and foliar plant nutrition. Materials and methods. The studies were carried out during 2019–2021 on the fields of the Department of Seed Production and Seed Science at the Institute of Agriculture in the Carpathian region NAAS. We studied next maize hybrids: Pochaivskyi 190 MV, DN Meotyda, DN Khortytsia, Orzhytsia 237 MV (the originator – State Enterprise Institute of Grain Crops of NAAS, Dnipro). Yield accounting was carried out by direct combining of experimental plots with subsequent weighing, and the obtained data was recalculated for standard grain moisture content. Processing statistical data - by analysis of variance (Excel, Statistica 6.0) according to V. A. Ushkarenko, R. A. Vozhehova, S. P. Golobo-rodko, S. V. Kokovikhin (2013), economic assessment – by the method of V. I. Boiko, E. M. Lebid, V. S. Rybka (2008). Results. The highest grain yield of maize hybrids (7.49 t/ha for early-ripening group and 7.62 t/ha for mid-early group) was obtained in 2019; in 2020, the grain yield was lowest – 7.07 and 7.22 t/ha, respectively. The highest yield of 7.68 t/ha was obtained for DN Meotyda hy-brid of the early ripening group, and 7.67 t/ha – for Orzhytsia 237 MV hybrid of the mid-early rip-ening group. Over the years of research, the variability of grain yield for the early ripening hybrids (FAO 100–199) ranged within 0.32–0.52 t/ha, for the mid-early ripening hybrids (FAO 200–299) – 0.22–0.35 t/ha. Pre-sowing seed treatment with chelated forms of microfertilizers was effective on gray forest surface-gley soils of the studied region with hard-to-reach forms of nutrients. Microferti-lizers used in pre-sowing seed treatment increased grain yield by 0.21–0.43 t/ha. Conclusions. The growth of economic indicators for farms of various forms of ownership in the Western Forest-Steppe zone is facilitated by the expansion of the range of simple linear maize hybrids of domestic selection.

The of the growing season is the main breeding trait, which determines the practical use of the initial material of popcorn in a particular agroclimatic zone. Thus, so the differentiation of samples on this trait is important and relevant. Issues. Most methods for determining FAO index of popcorn lines and hybrids (Zea Mays L.) are based on the standard with a certain maturity group, while for maize (Zea Mays L. everta Sturt.) such standards are not available. Purpose. To determine the FAO index of new popcorn lines on three indicators: the number of leaves per a plant, the effective temperature sum during the growing season, and the growing season duration. Materials and Methods. The initial material was 46 popcorn lines in S5, which were developed in the Food Maize Breeding Laboratory at the Institute of Grain Crops of NAAS of Ukraine. The field trials were carried out at the Synelnykove Breeding and Research Station during 2020–2021. The FAO index of popcorn lines was determined according to Adryushchenko and Kryvytsky’s method. Results. We have determined the growing season duration of new popcorn lines according to the FAO classification by three indicators: the number of leaves per a plant, the effective temperatures sum during the growing season and the number of days until full ripening. Conclusions. It was noted that the indicator values that determine the maturity group of S5 popcorn lines can vary with growing conditions. Therefore, when only one indicator is used, we cannot obtain the accurate results. It is possible to reliably identify the maturity groups of initial material by the means of the proposed method of FAO determination on three indicators. Based on the results of the research, the new popcorn lines were divided into 3 groups. It was found that the mid-early ripening group (FAO 240-250) includes 4 lines in S5 - IKR 2-1, IKR 11-9, RV 3 and RV 1; to the mid-ripening group (FAO 320-390) – 32 lines in S5, including RR1, RR11, RS 13, RB 3, RK 43, RK 32, IKR 11-3, etc.; to the mid-late ripening group (FAO 400 - 410) - 10 lines in S5, including RV 18, RV 11, RP 61, RS 3, RV 6, etc.. It is proposed to select the lines of mid-early and mid-ripening groups for developing the new popcorn hybrids with full-value food popcorn grain. The formed working collection includes 80.4 % of samples of these maturity groups. Key words: breeding, popcorn, line, FAO maturity index, growing season, effective temperature sum.","PeriodicalId":23071,"journal":{"name":"The Scientific Journal Grain Crops","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88364539","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 level of genetic yield potential and adaptive properties of modern bread winter wheat varieties at this stage of breeding development is at a fairly high level. So breeding, improve-ment of bread winter wheat is becoming increasingly difficult. For this purpose, the creation and identification of new genetic sources of valuable traits and creation of genetic diversity, evaluation and selection of desired genotypes is extremely relevant. Issues. Introduction of alien translocations into the gene pool of bread winter wheat can serve as one of such sources of new original genetic material. However, the effects of these translocations are manifested to varying degrees depending on the genetic environment of hybrids and agroclimatic conditions of genotype selection. Aim. To compare the changes in the yield of recombinant lines and plant productivity elements based on their drought and heat tolerance depending on their genetic effects of wheat-rye translocations (WRT) 1AL.1RS and 1BL.1RS. To determine the use effectiveness of each WRT in order to create more perfect varieties of bread winter wheat under the conditions of soil-air drought in the Steppe zone of Ukraine. Materials and Methods. In 2010-2020, field trials were carried out on the Institute’s fields on the by black fallow as the annual predecessor with the optimal agricultural background for breeding work. During the analysis of experimental data, all changes in meteorological conditions over the years of research were taken into account. In general, weather conditions were arid, which is typical for the Steppe zone. The studies of 112 lines (9.2 %) were carried out in the Department of Genetic Basis of Breeding of the Plant Breeding and Genetics Institute at the National Center of Seeds and Cultivar In-vestigation led by A. I. Rybalka, the rest 1093 lines (90.8 %) were studied in the Institute of Plant Pro-tection NAAS led by N. A. Kozub and I. O. Sozinov. The material of competitive variety trials was tested on the presence of translocations and their state by DNA markers in the Department of General and Molecular Genetics of the the Plant Breeding and Genetics Institute at the National Center of Seeds and Cultivar Investigation led by V. I. Fait. Mathematical processing and analysis of the study results were performed using the methods of B. A. Dospekhov and P. F. Rokitskyi, and with Microsoft Excel 2007. Results. It was established that genetic effects of the most widespread in the world breeding practice wheat-rye translocations 1АL.1RS and 1ВL.1RS are considerably modified by features of their interaction in genetic environment and depending on agroclimatic conditions of growing introgressive genotypes. The positive effect of 1AL.1RS on the yield, total and productive tillering, and head productivity elements was significantly revealed due to simultaneous positive effect of translocation on drought and heat tolerance of plants.
