Background. In the present-day situation, the problems pertaining to the nutritional quality of food and feed are quite pertinent for fodder production and cereal farming. The prospect to exploit hulless barley is regarded as a promising trend of agricultural research, because its grain contains chemical compounds of higher value than those in hulled barley. However, among the limiting factors of hulless barley cultivation, low yield should be mentioned, along with poor lodging resistance and susceptibility to fungal diseases. Therefore, the task of searching for and comprehensive studying of source material for hulless barley breeding is essential as the first step towards the development of high-yielding and adaptable cultivars.Materials and methods. Twenty hulless barley accessions, representing 15 botanical varieties, served as the target material for the study. Their genotypes were evaluated in the northern forest steppe environments of Tyumen Province (2015– 2017) according to the guidelines developed by the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) and field trial methods by B. A. Dospekhov. Correlation analysis was used for statistical processing of experimental data.Results and conclusion. The degree of interactions between the studied characters was measured, and their effect size in the formation of the yield was shown for hulless barley accessions. An inverse correlation of medium strength (r = –0.37) was observed between plant height and lodging resistance, and a direct relationship between plant height and yield was recorded (r = 0.37). The yield was most closely associated with grain weight per plant (r = 0.61) and 1000 grain weight (r = 0.54). The research results showed that C.I.10975 (k-30624, Ethiopia), Liguleless (k-29894, Tajikistan), Schwarze Nackte Kraftborn (k-25788, Germany) and ‘De printempe’ (k-23491, France) had relatively high yield combined with a number of other useful traits.

In the conditions of the Kirov region, 375 samples of soft spring wheat of various ecological and geographical origin (from 30 countries) of the Federal Research Centre N. I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) collection were studied. The assessment of the source material by yield, duration of the growing season, plant height, lodging resistance, productivity of the ear and plant, 1000-grain mass is presented in the form of a 9-point system of the severity of the trait for three years of field study. As sources for breeding, varieties that combine high yield (5.0...9.0 points) with a high level of economically valuable traits (7.0...9.0 points) were identified. The maximum average point (9.0) for yield capacity was noted by the variety Karabalykskaya 91 (Kazakhstan). The optimal height (53.9...74.0 cm) and lodging resistance were noted in the varieties: Estivum 155 (Russia), Kvorum (Ukraine), Epos, Ethos, Nandu, Schenk and KVS Akvilon (Germany), AC Phil and PT-741 (Canada), Hybrid (Mexico), Leguan (Czech), PS-133 (China) and SSL 25-2 (USA). Early maturation was distinguished in the domestic varieties Skala and Iren (80...87 days). The samples Line 3691h, Izida, FPCh-Ppd-m, Gerakl, Sibirskaya 16 (Russia), Kvorum (Ukraine), Attis and Nandu (Germany), Musket (England) were distinguished by the length (7.3...8.8 cm) and the number of grain of the main ear (32.1...39.9 pcs.). The varieties Voronezhskaya 16, Gerakl, Saratovskaya 72, Saratovskaya 73, Sibirskaya 16, Serebristaya, FPCh-Ppd-m and Ekada 6 (Russia), Anshlag and Kvorum (Ukraine), AC Gabrieland Hoffman (Canada), Attis and Nandu (Germany) were distinguished by a high grain weight per ear (1.28...1.58 g). The varieties Zakamskaya (Russia), Rassvet (Belarus), AC Cadillac (Canada) and PS-95 (China) are recommended as sources of high protein content. It is shown that the wheat yield in the region is closely related to the plant height (r = 0.67), the ear and plant productivity elements (r = 0.24...0.41), the protein content (r = -0.49) and does not depend on the 1000-grain mass (r = 0.04). Sixteen samples were identified with complex resistance to dominating fungal diseases. Samples Altajskaya 110, Kinelskaya 61, Line 2, Lutescens 30 and Estivum V313 (Russia) combined high yield with aluminum resistance. Varieties Altajskaya 100, Baganskaya 95, Line 3691h, Novosibirskaya 20 and Estivum 155 (Russia), Klein Vencedor (Argentina) and NOS Norko (Germany) were characterized by high yield and drought resistance. Based on the obtained results, a bank of sources of economically valuable traits was created, which allows to involve genotypes adapted to the conditions of the region in the breeding process.

An increase in spring barley acreage requires a detailed study of the interaction of agronomic and climatic factors, as well as the selection of a modern set of new varieties. The use of mineral fertilizers is one of the most important methods to improve the productivity of grain crops and maintain a deficit-free balance of mineral nutrients in arable soils. The current study of the effective use of various doses of mineral fertilizers (NPK) on the new spring barley variety ‘Znatny’ was carried out on dark-gray forest heavy loamy soil in 2018–2020 by the Institute of Seed production and Agrotechnologies, a branch of the Federal Budgetary Scientific Institution “Federal Research Agro-Engineering Center VIM”. There has been established that the date of the phenological phases and the length of interphase periods did not depend on fertilizer rates, but had a close correlation with weather conditions (r = +0.68). The analysis of the obtained data has shown that an increase in the rates of applied fertilizers increases the aboveground biomass, which, in turn, negatively affects productivity of the barley variety ‘Znatny’ (r = -0.77). The analysis of the yield structure and rates of fertilizers NPK has shown that in the trial, the spring barley productivity was influenced by 1000-grain weight (r = +0.60). There was found a high inverse correlation between productivity and length of head (r = -0.85). When length of head ranged from 7.5 to 8.4 cm, grain weight per head remained practically at the same level in all variants (1.1–1.2). This indicated that at a rate of N90P90K90 and N120P120K120, the variety ‘Znatny’ formed a not very dense head. Protein percentage at these rates also greatly reduced. According to the obtained data, an increase in the doses of applied fertilizers (N90Р90К90–N120Р120К120) resulted in the intensified development of most leaf diseases and a decrease in lodging resistance. Thus, the optimal dose of application of azophoska fertilizer on dark-gray forest soil is the norm N45P45K45, since on this option there was obtained maximum productivity and net income. the increase in the recom[1]mended norms of mineral fertilizers, sharply reduces profitability of crop cultivation.

The aim of the study is to isolate from collection samples of winter triticale the sources of short-stemming and high grain yield for their further involvement in the selection process in the forest-steppe conditions of middle Volga region. The studies were carried out in 2013–2017 on typical gray forest soils. 93 samples of winter triticale of Russian selection, obtained from the collection of All-Russian Institute of Plant Genetic Resources named after N.I. Vavilov. Standard is Bashkir short-stemmed. Weather conditions during the years of study varied significantly. The studied gene pool has a wide genetic diversity in plant height (65 ... 136 cm) and yield (277 ... 579 g/m2). According to the results of analysis of variance, a significant influence of the genotype and year conditions on the manifestation of these characters was established. Plant height and yield depended on both factors and their interaction, but the first trait is determined mainly by the heredity of the varieties (46.1%), and the second - by the growing conditions (61.8%). There was a significant variation in the values of the studied indicators, both by genotypes and by years: the coefficient of intervarietal variation in the average values of the traits of grain yield and plant height for 2013–2017 amounted to 15.0 and 17.2%, respectively, with variation by years 15 , 4 ... 30.7% and 15.1 ... 20.1%, respectively. According to the results of regression analysis, it was found that within the studied gene pool the highest grain yield was formed by samples with a plant height of 86 ... 105 cm. 13 sources of short-stemming with a plant height below 80 cm and 17 high-yielding samples with a yield of 515 ... 579 g/m2 were identified. In these genotypes, the yield excess over Bashkirskaya short-stemmed standard was significant and amounted to 33 ... 97 g/ m2, or 6.8 ... 20.1%. The varieties Tribun, Skif, Kentavr, Sotnik are characterized by the highest breeding value

A study was conducted to examine relationship between important traits of durum wheat and their direct and indirect effects on grain yield. Research work was conducted during the winter season of 2009-10 under irrigated optimum seeding condition at Regional Agricultural Research Station, Bangladesh Agricultural Research Institute, Ishurdi, Pabna with 10 advanced genotypes. A wheat variety was used as check. Positive and significant correlation was found for plant height, spikes/m2, and 1000-grain weight with grain yield. Head days and maturity days showed considerable negative correlation with grain yield. Maturity days, spikes/m2, and 1000-grain weight had significant positive direct effects on grain yield. Grains/spike had direct positive effect but in low magnitude. The indirect effect of head days and plant height on grain yield was found mainly through maturity days and 1000-grain weight. It can be concluded that more emphasis should be given on head days and plant height along with 1000-grain weight, spikes/m2, and grains/spike during selection for dururn wheat improvement.

The article discusses the results of a four-year study (2016-2019) of breeding lines of spring soft wheat of the selection of Federal Agricultural Research Center of the North-East named N.V. Rudnitsky in the soil and climatic conditions of the central and southern parts of the Volga-Vyatka region. The promising lines C-65, C-103, H-154 were selected as they exceeded the regionalized standard variety Simbirtsit in average yields (3.41...3.56 t/ha; the increase is 0.04...0.19 t/ha), and in terms of potential yield (5.61…6.93 t / ha; the increase is 0.48...1.80 t/ha). According to the long-term average indicators of the crop structure, the selection lines П-57, P-63, С-65 and С-103 were attributed to the sources of valuable properties. Genotypes P-63, H-154 showed higher values and stability of gluten formation in grain relative to the variety Simbirtsit (22.8-24.1%; the increase to the standard is 3.1 - 4.4%). Using the variation coefficient, the degree of variability of economically useful traits (productive bushiness, plant height, ear length, number of grains per ear, grain weight per ear, 1000 grain mass, yield, gluten content in grain) was determined in different ecological environments. It has been established that the variability values of individual characteristics of productivity in one variety are not always consistent with each other and have genotypic conditionality. Yield stability can be closely related to the level of variation of individual elements of its structure. Genotypes that were more stable in yield indicated high variability of productive bushiness and low variability of plant height, grain weight per spike, and mass of 1000 grains. It has been shown that from practical point of view the most valuable genotypes were the ones with steadily high values of the spike length and the number of spike grains, as having a high adaptive response to cultivation conditions.Conflict of interest: the authors stated that there was no conflict of interest.

One of the effective ways of creating high-yield tobacco varieties is the selection of donors of economically valuable characters and their optimal combination in new plant genotypes. Sources for selection and creation of such donors are gene pool collections, which concentrate source material of different geographical origin with a set of valuable breeding and genetic characters. The level of expression of these characters is modified by breeding conditions and the response of the genotype to environmental factors. Therefore, the main purpose of our research was to study the manifestation of morpho-biological features and properties of plants of tobacco collection samples in agroclimatic conditions of the Central Forest-steppe of Ukraine, establishment of breeding value of available gene pool of culture, selection of sources of economically valuable characters and formation of working tobacco collection. The strategic task of research is to create the varieties that are able to maximize the use of their genetic potential in a specific region, to be resistant to stressful environmental conditions, to ensure a high realization of the genetic potential of productivity. For the first time in the conditions of the Central Forest-steppe of Ukraine the analysis of 30 collection samples of tobacco of different ecological and geographical origin was carried out. New genetic sources for morphological character of plants, raw yield, seed productivity and early maturity, which are used at the Experimental station of tobacco farming National Research Center "Institute of Agriculture of the National Academy of Agrarian Sciences" in variety breeding, were identified. A certificate of registration of the working collection of tobacco gene pool of the present on morphological characters was received from the National Center for Plant Genetic Resources of Ukraine, according to the results of research in 2017–2019 (Certificate № 277 from 29.10.2019).

Introduction of semi-dwarfism and early maturity in rice cultivars is important to achieve improved plant architecture, lodging resistance and high yield. Gamma rays induced mutations are routinely used to achieve these traits. We report the development of a semi-dwarf, early maturing and high-yielding mutant of rice cultivar ‘Improved White Ponni’, a popular cosmopolitan variety in south India preferred for its superior grain quality traits. Through gamma rays induced mutagenesis, several mutants were developed and subjected to selection up to six generations (M6) until the superior mutants were stabilized. In the M6 generation, significant reduction in days to flowering (up to 11.81% reduction) and plant height (up to 40% reduction) combined with an increase in single plant yield (up to 45.73% increase) was observed in the mutant population. The cooking quality traits viz., linear elongation ratio, breadthwise expansion ratio, gel consistency and gelatinization temperature of the mutants were similar to the parent variety Improved White Ponni. The genetic characterization with SSR markers showed variability between the semi-dwarf-early mutants and the Improved White Ponni. Gibberellin responsiveness study and quantitative real-time PCR showed a faulty gibberellin pathway and epistatic control between the genes such as OsKOL4 and OsBRD2 causing semi-dwarfism in a mutant. These mutants have potential as new rice varieties and can be used as new sources of semi-dwarfism and earliness for improving high grain quality rice varieties.
