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

Adaptibility, plasticity, stability and stress resistance of the oats variety are seen as significant for obtaining stable oat yields with high grain quality. The research aims at assessment of the adaptive capacities of oat varieties selected at Omsk Agricultural Research Centre. The assessment was carried out by means of statistical parameters calculated on the basis of protein concentration in the grain. The experiment was conducted in 2011-2016 on the experimental fields of Omsk Agricultural Research Centre which is located in the southern forest-steppe of Omsk. Protein concentration in the oat grains averaged 11.2% in chaffy varieties and 16.2% in huskless varieties. Following S.A. Eberhart and W.A. Russell assessment, such varieties as Orion, Irtysh 13, Irtysh 21, Irtysh 23, Tarskiy 2, Fakel and Sibirskiy Gerkules combined high stability and response to better environmental conditions. Sibirskiy golozernyy, Progress, Skakun and Levsha varieties are characterized as varieties that responded to the conditions of cultivation (following S.A. Eberhart and W.A. Russell the coefficient of linear regression was 1.06 ÷ 1.72; according to V.A. Dragavtsev the coefficient of multiplicity varied from 2.05 to 2.60). The authors observed high resistant varieties (-1.60 ÷ -2.47) as Pamyati Bogachkova, Irtysh 13, Irtysh 23, Tarskiy 2, Skakun and Irtysh 21. Levsha, Sibirskiy golosernyy and Progress varieties were characterized by high degree of correspondence between environmental factors and genotype (according to A.A. Rossielle and J. Hemblin, compensatory capacity was 15.02 ÷ 16.32). Levsha, Sibirskiy golozernyy and Progress varieties refer to plasticity varieties (according to A.A.

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).

Spring Soft Wheat

In 2013-2019 in the conditions of Kirov region 178 varieties of spring soft wheat from the collection of the Federal Research Center of N.I.Vavilov All-Russian Institute of Plant Genetic Resources (VIR) were studied according to loose smut resistance, plasticity and yield stability. Among studied varieties 36 immune and 12 practically immune to loose smut infestation samples have been revealed. They can be used as sources of resistance in selection. The most favourable conditions for infestation of spring soft wheat plants with loose smut develop since the beginning of blossoming till grain filling. The higher the air temperature and the amount of precipitation during this period, the higher is the percentage of wheat plants affected with this disease. As the percentage of the stems affected by loose smut increased, total yield losses grew as well (r = 0.99). Nineteen varieties of spring wheat significantly exceeded the standard variety Bazhenka (Russia) in yield on an infection background. Five mid-susceptible varieties which showed tolerance to the disease have been selected. They are Tulaykovskaya Nadezhda (Russia), Samgau, Dostyk, Karabalykskaya 91 (Kazakhstan) and Visa (Belarus). During the years the following varieties revealed the highest and stable productivity: Stepnaya 50, Dostyk (Kazakhstan), Kazanskaya Yubileynaya, Niva 2, Provincia, Egisar 29, Sudarushka, Tulaykovskaya Nadezhda (Russia), Hoffman (Canada), UL Pettit (USA) and Leguan (Czechoslovakia). The following varieties were designated as the intensive type: Tyumenskaya 26, Elizaveta, Maria 1, Melodiya, Niva 2 (Russia), Kharkovskaya 10 (Ukraine), Samgau (Kazakhstan), Visa (Belarus), and American varieties Ranger and UL Pettit (b i > 1). Varieties Ranger and UL Pettit showed high productivity in favorable cultivation conditions. Varieties Mazhor (Ukraine), Favorit (Russia) and Karabalykskaya 91(Kazakhstan) (bi<1) should be used on an extensive background. By deterioration of cultivation conditions the productivity of these varieties decreased insignificantly. The relationship between productivity and adaptability parameters has been established (bi , Ноm). The highyielding varieties have been characterized as more plastic (r = 0.69) and stress resistant (r = 0.73).

The aim of the article is to summarize the results of plant gene pool samples introduction into the National Plant Genebank from different countries and ecological and geographical zones for use in domestic breeding. Results and Discussion. In 2016 – 2018, 5984 samples were introduced to the Centre for Plant Genetic Resources of Ukraine using various information sources, including 2093 samples from Ukraine and 3891 from foreign countries. The greatest samples variety was attracted by cereals, leguminous, fodder, medicinal and essential oil, vegetable and melon crops, corn. Seeds of new forms having valuable properties are attached from research and breeding institutions of Ukraine. The samples of foreign origin were most actively introduced through cooperation with research institutions of Russia, Belarus, and Moldova. A significant number of samples came from genebanks in Europe: the Czech Republic, Italy, France, Germany, the Netherlands; Asia: Kazakhstan Turkey, Israel, China as well as from South (Mexico) and North America - USA, Canada. The ways of pre-adaptation and adaptation of samples from geographically remote regions for use in Ukraine are indicated. To collect local cultural and wild-growing samples of different crops, collecting missions were carried out in the central and southern regions of the forest-steppe and northeastern regions of Ukraine during which 1641 gene pool samples were collected. For the Red Book species of plants and species that are not listed in the Red Book of Ukraine but are rare or are threatened with extinction under natural conditions, a points have been identified for possible arrangement of in situ conservation reserves. A number of objects with a rich genetic diversity of fodder and medicinal plants have been identified, on which it is necessary to monitor coenoses and ensure in situ conservation. The introduced samples were transferred for use in research and breeding programs in Ukraine. Conclusions. The definition of a model of ecologically adapted in Ukraine genotypes of different crops that are carriers of valuable traits from countries with similar climatic conditions as well as from geographically remote regions, has made it possible to increase the efficiency of introduction and to more specifically search and attract to the National Genebank the plant samples with the necessary manifestation levels of economic and biological traits.

Wide Range

Among the many diseases of spring wheat caused by pathogenic fungi, loose smut Ustilago tritici (Pers.) Jens. remains to be a dangerous disease with a wide range of distribution. In fields where there is no control over the emergence and spread of the disease, the yield reduction can be up to 10 %, and in the case of highly susceptible varieties, up to 40–50 %. Taking into account the increasing cost of seed protectants and their environmental damage, the cultivation of varieties resistant to loose smut is still the most affordable way to protect plants, reducing the pesticide load on agrocenoses. The crucial point in breeding for resistance is the use of resistant varieties as parental forms. The aim of our research was to isolate samples of spring wheat that are immune to loose smut against the background of artificial infection of plants with a population specific to the West Siberian region. The article presents the results of long-lasting studies of 350 genotypes of spring wheat of different ecological and geographical origin for resistance to disease. Physiological specialization of races was carried out on the basis of a differentiating set consisting of six varieties of soft wheat and three varieties of durum spring wheat. The obtained results in combination with literature data reveal changes in the racial composition of the pathogen population over the past 30–35 years. Varieties of foreign and domestic selection resistant to the West Siberian population of loose smut have been identified. Based on the analysis of pedigree samples, highly and practically resistant to loose smut, we concluded that in breeding for immunity to U. tritici, the same sources of resistance genes are most often used. Among the gene pool of spring wheat of foreign selection, the largest number of genotypes resistant to loose smut is assigned to the countries of the North American geographical zone (USA, Canada, Mexico). These are largely samples containing Ut1 genes, genes from spring wheat ‘Thatcher’ and its sister line ‘DC II-21-44’. Resistance genes in Russian wheat varieties can be traced from cultivars Beloturka, Poltavka, Selivanovsky Hare (using Saratovskaya 29 and its derivatives), and genes from wheatgrass lines AGIS 1 and Grecum 114.

Early Ripening

Over the past century and at the beginning of the current one, Siberian breeders have been intensively breeding spring soft wheat for improving the yield and grain quality. The ecologically and geographically diverse source material has been used at the breeding and educational institutions of the region. Thus, in the severe Siberian conditions, the wheat gene pool has been painstakingly created. It has been very difficult here to solve the problem of improving the grain quality, but, given the determination and the talent of many breeders and geneticists, the gene pool of valuable and strong wheat varieties has been created. As a result, being formerly a consumer of food wheat, Siberia has now become a region producing high-quality grain for domestic use and sale in the foreign market. The gene pool of spring soft wheat, which is so rich in the volume and quality, has not been studied in full, and not used throughout Siberia. In 2013 – 2015, sixteen valuable and strong varieties of Siberia-bred wheat had been studied in the northern zone of the Tyumen region on the experimental field of the Northern Trans-Ural State Agricultural University. It has been found that the average productivity of the early-ripening Novosibirskaya 16, Tulun 15, and Polyushko varieties over the three years amounted to 2.52 – 2.89 t/ha, and was close to the yield (2.35 – 3.10 t/ha) of the middle-early ripening varieties. In the midseason-ripening group, the Alyoshina and Altayskaya 110 and 325 varieties exceeded the Tyumen-bred standard Lutescens 70 by 0.23 – 0.69 t/ha with the yield of the latter being 2.54 t/ha. In terms of the content and quality of gluten, the following varieties stood out: Iren, Novosibirskaya 15, Tulun 15, Polyushko, Omskaya 36, Skala, Boyevchanka, Pamyati Vavenkova, Tyumenskaya 80, Alyoshina, and Altayskaya 325. In terms of baking properties (3.7 – 4.2 points), the following varieties stood out: Iren, Novosibirskaya 15, 29, 31, Polyushko, Skala, Boyevchanka, Pamyati Vavenkova, Tyumenskaya 80, Tulunskaya 12, and Altayskaya 325, which can be used as the source material for further wheat breeding.

Assessment of adaptability, environmental plasticity and stability of crop varieties in different climatic conditions is an important direction of the selection process. The purpose of the research was to assess the ecological plasticity and stability of 5 varieties (Premiera, Slavyanka, Ros, Kinelskoye 63, Dershavnoe) and 3 lines (L-28/14, L-141/14, L 34/14) of grain sorghum, to identify the role of abiotic factors in the dynamics of its grain yield at the final stages of selection in the competitive testing of varieties. The studies were carried out in the forest-steppe of the Samara region in experimental fields and in the laboratories of the Volga Research Institute of Breeding and Seed Production in 2015-2018 according to the dispersion methods of A.V. Kilchevsky and L.V. Khotyleva, S.A. Eberhart and W.A. Russel. According to the ecological plasticity variety Ros and line L-34/14 were of intensive type. Varieties Derzhavhoe, Kinelskoye 63, Slavyanka and line L-28/14 belonged to the semi-intensive type. Variety Premiera and line L-141/14 were of extensive type. The combination of high productivity and stability was observed in varities Kinelskoye 63, Derzhavnoe, L-28/14 with high parameters of breeding value of genotype. Promising sample L-28/14 with high productivity and environmental stability is recommended for transfer to the state variety testing.
