Under conditions of climate change, the assessment of the stability of genotypes is of particular importance. To conduct directed selection of genotypes with a narrow or broad reaction rate, it is necessary to assess their stability already in the early stages of breeding. The aim of the study was to study the stability of breeding significant traits of oat and barley samples in contrasting ecological and geographical conditions. 25 oat samples and 25 barley samples were studied over 3 years under contrasting conditions in St. Petersburg and the Tambov region. Varieties are characterized by average values of economically valuable traits and genotype regression coefficients on the influence of the bi environment according to Eberhart and Russell. The most sensitive to a change in the ecological and geographical situation were the durations of the germination-heading, germination-harvest periods and grain yield. These characters varied to a greater extent depending on the cultivation conditions than on the genotype. According to regression coefficients for environmental conditions, significant differences in genotypes were only in yield. Contrasting groups of varieties were distinguished by regression coefficients on environmental conditions, genotypes with high productivity. The durations of germination-heading, germination-harvest, the plant height reacted to the change in the environment the same in different varieties. The duration of the growing season was determined by the sum of effective temperatures above 15C. The reduction of the growing season in both crops was 3 days with an increase in the sum of effective temperatures above 15C by 100C.

At the first stage of breeding, the new source material was created to obtain a variety of daikon resistant to abiotic factors with high productivity and commercial qualities, better taste, and biochemical properties. Eighteen samples from Russia, Ukraine, Belarus, China, Korea, and Japan were in the nursery of the original forms. The following breeding types were used in the hybrid nursery: 1) crossing of several morphologically close samples originating from geographically remote areas; 2) paired crosses of morphologically and biologically different samples. Breeding was carried out on an accelerated scheme: before harvesting, samples were evaluated for resistance to bolting, shape and color of the roots, taste qualities, and affection with diseases; in February, the roots were planted in temporary greenhouses in pairs for hybridization; seeds were threshed in mid-July; the hybrid seeds were sown on the roots in early August; the roots were harvested and evaluated 60-65 days after the moment of sprouting. Then, the 1.5-year cycle was repeated until the constant lines were obtained. Yield fluctuations were determined by taking into account the sum of effective temperatures and precipitation for the period “sprouting – harvest” [4]. Slight variability in the yield at high agronomic stability was observed for the varieties Sokol, Gulliver, and hybrid No. 41. The standard (variety Klyk slona) differed from other varieties by high variability in the yield and insufficiently high agronomic stability (66%). We found that there was the fluctuation of the yield of modern varieties: Klyk slona by 22 t/ha, Gulliver by 9 t/ha, Sokol by 14 t/ha, and hybrid No. 41 by 15 t/ha. It was estimated that for every 1 degree Celsius rise in the amounts of effective temperatures the yield of the aforementioned varieties decreased: 9.7; 38; 7.4 and 66 kg/ha, respectively. And, vice versa, if the amount of precipitation increased by 1 mm, the yield of Klyk slona would increase by 17 kg/ha, Gulliver - by 10 kg/ha, Sokol - by 11 kg/ha, and hybrid No. 41 – by 6 kg/ha. The technology and method for initial seed production of daikon have been developed with the preserved economic and biological characteristics. The daikon variety Sokol was created and included in the State Register.

Подсолнечник в Российской Федерации – это основная масличная культура. Для рекомендации оптимальных регионов возделывания и активного внедрения в производство сортов и гибридов подсолнечника важно знать адаптивный потенциал, который оценивают по величине параметров экологической пластичности и стабильности. Выбор сорта должны определять лимитирующие факторы того региона, в котором его будут выращивать. В условиях Пензенской области изучены гибриды подсолнечника компаний Сингента (четыре гибрида), Евралис (один гибрид), Майсадур (один гибрид) и Пионер (один гибрид) по комплексу хозяйственно-ценных признаков и экологической пластичности. Установлено, что самый короткий период вегетации был у гибрида Бакарди и составил 114 дней. Более позднеспелым оказался гибрид компании Майсадур Мас 80 ИР, вегетационный период которого составил 125 дней. Высота растений у изучаемых гибридов подсолнечника находилась в пределах 166-174 см. Низкорослым гибридом в опыте был гибрид Амис компании Евралис, высота которого составила 166 см, а высокорослым гибрид Фортими (174 см). В среднем за два года урожайность гибридов подсолнечника в опыте колеблется от 2,05 до 3,25 т/га. Средняя урожайность по всем гибридам составила 2,7 т/га. Превысили среднюю урожайность гибриды компании Сингента – Фортими (2,9 т/га), Тристан (2,85 т/га), Бакарди (3,25 т/га) и гибрид ПЕ 63 ЛЕ 10 компании Пионер (2,95 т/га). Индекс экологической пластичности изменяется от 0,76 до 1,2. Экологически пластичными являются все гибриды компании Сингента (Неома, Фортими, Тристан, Бакарди) и гибрид компании Пионер (ПЕ 63 ЛЕ 10). Индекс экологической пластичности, соответственно, равен 1,0-1,2 и 1,09. Остальные гибриды требуют к себе повышенного внимания при возделывании. Sunflower in the Russian Federation is the main oilseed crop. To recommend the optimal cultivation regions and the active introduction of sunflower varieties and hybrids into production, it is important to know the adaptive potential, which is assessed by the value of the parameters of phenotypic plasticity and stability. The selection of a variety should be determined by the limiting factors of the region in which it will be grown. In the conditions of the Penza region, sunflower hybrids of Syngenta (four hybrids), Euralis (one hybrid), Maysadur (one hybrid) and Pioneer (one hybrid) were studied for a set of economically valuable traits and phenotypic plasticity. It was found that the Bacardi hybrid had the shortest growing season of 114 days. The Mas 80 IR hybrid by Maysadur turned out to be late ripening, the growing season of which was 125 days. The plant height in the studied sunflower hybrids was in the range of 166-174 cm. The low-growing hybrid in the experiment was the Amis hybrid by Euralis, the height of which was 166 cm, and the tall one was the Fortimi hybrid (174 cm). On average, for two years, the yield of sunflower hybrids in the experiment ranged from 2.05 to 3.25 t/ha. The average yield for all hybrids was 2.7 t/ha. The Fortimy (2.9 t/ha), Tristan (2.85 t/ha), Bacardi (3.25 t/ha) hybrids by Syngenta and the PE 63 LE 10 hybrid by Pioneer (2.95 t/ha) exceeded the average yield. The phenotypic plasticity index varied from 0.76 to 1.2. All hybrids of the Syngenta company (Neoma, Fortimi, Tristan, Bacardi) and the hybrid of the Pioneer company (PE 63 LE 10) are environmentally plastic. The phenotypic plasticity index is 1.0-1.2 and 1.09, respectively. The rest of the hybrids require increased attention during cultivation.

The ascorbic acid content of five varieties of black currants during 15 years of research is given. During the growing season of black currant it was counted: the sum of effective temperatures above 5 °C; the sum of effective temperatures above 10 °С; amounts of active temperatures; amount of rainfall; hydrothermal coefficient (HTC). The research objective was to analyze ascorbic acid content in black currant fruit during many years of research. Research tasks were meant to establish black currant growth duration and agroclimatic indicators during this period; ascorbic acid content in black currant fruits depending on the variety and the year of the harvest. It is established that the duration of the black currant growing season in the conditions of the Right-Bank Forest-Steppe of Ukraine is 96±3–4 days for thermal resources: the sum of effective temperatures is above 5 °С – 750–950°, the sum of effective temperatures is above 10 °С – 300–600°, the sum of active temperatures is 1050–1300° and the rainfall is 120–300 mm, for the HTC it is 0,7–3,0. The regularities of ascorbic acid synthesis are shown depending on the features of the variety and agroclimatic indices during vegetation of plants. The analysis of the received data shows the ambiguous influence of the HTC indicator on the accumulation of ascorbic acid in black currant fruits. A comprehensive and comprehensive study of the most complex details of the metabolism of substances showed that ascorbic acid plays one of the crucial roles in the entire cycle of intrauterine development of plants from emergence to disappearance - the role of a direct participant in the process of respiration, photosynthesis, regulation of the activity of enzymes and coenzymes, general metabolism and transport of substances, protecting cells from oxidative stress caused by abiotic factors. Thus, the high C-vitality of black currant fruit depends to a large extent on the variety, and only then on weather conditions during the formation of the harvest.

Purpose: Comparative assessment of the fullness of lactation of primarmels of different genotypes.Materials and methods. The article presents the results of the assessment of the lactation activities, which was carried out in the SEC "Kazminsky" Kochubeevsky district of the Stavropol region on the livestock of the black and motley breed of local and brown populations from the Vologda region from LLC "Zaozerier" (farm №. 1) and SHPK "Proseukhon" (farm №2). Three experienced animals groups of 30 goals were formed in each, studies were carried out according to generally accepted methods.Results. The greatest amount of milk for 305 days I lactation was obtained from the first elevations brought from LLC "Zaozerier" - 7368 kg, which is 3.64% more than from the cows of their own reproduction and 8.85% more than from animals grown in SEC "Proseukhonskoye". The lactation stability ratio was calculated in two ways, and in both cases there was more than 100, the factor of the fullness of lactation in the cows of the studied genotypes this indicator was also very high and amounted to 87.7-91.6, which indicates a high level of breeding and tribal work, and On the significant influence of genetic factors on the lactation activity of the studied animals. According to the nature of the lactation curve, the pilot of all three genotypes can be attributed to the I type - high stable lactation. However, the greatest amount of milk from cows was obtained in the third phase of lactation.Conclusion. Thus, it can be concluded that the period of adaptation did not have a significant impact on the lactation activity of the delivered first elements. The animals studied were characterized by high productivity and sustainable lactation.It is desirable when evaluating the cows, along with productivity for 305 days of lactation, consider individual qualities and the ability to hold high productivity to a large part of the lactation period. For more differentiated selection of cows in the breeding group, we recommend using the stability coefficients and the usefulness of lactation.

The article presents the results of mathematical modeling based on the construction and usage of different images of an object, process or system. The research expected to study the dependence of the productivity level and the economically valuable features of corn hybrids in the form of mathematical models. Field studies were carried out during 2011-2017 at the field of research of the Department of Plant, Selection and Bioenergy Crops of SE EF “Kordelivske” of IP NAASU of Vinnytsia National Agrarian University under the conditions of the Forest-Steppe of the Right-Bank, in accordance with the recommendations presented in the Methodology Of The Maize Field Study. The soils in the study variants are represented by black earth soil of deep medium loamy on the loessial soil. The humus content (according to Tiurin) in the tilth soil was 4.60%. Soil reaction - pH (salt) 5.7. The soils contain lightly hydrolyzed nitrogen (according to Kornfield) 106 mg per 1 kg of soil, mobile phosphorus and exchangeable potassium (according to Chirikov) 186 and 160 mg per 1 kg of soil, respectively. The experiments established the economic and biological evaluation of corn hybrids depending on the sowing period, the size of the fraction and the depth of seed wrapping, foliar fertilizers by micro fertilizers. The plot area for hybrids was 10.5 m2. Repeatability in experiments for hybrids is 3 times. Placement of plots is by the method of randomized blocks. An ecological-genetic model of quantitative features was used to study the phenotypic productivity of maize hybrids and to establish the influence on the formation of their traits. The model construction is based on the hierarchy of production traits demonstration in ontogeny and the correspondence of their manifestation in organogenesis. The model consists of three modules of features, i.e. the resultant and two components which reflecting the phenotypic implementation of the genetic formula. Resulting features are those that have an environmentally stable relationships and the highest total contribution to the intended property, yield. As a result of the conducted research, the mathematical models of the duration of the growing season of early-maturing maize hybrids allowed us to determine that the biggest influence does sums of effective temperatures (≥ + 10° C) for May, June, August and September over correlation rate at r = -0.62 and r = -0.51, r = 0.59 and r = 0.39, respectively. Also precipitation amount significantly influenced on the duration of the growing season and the correlation coefficient was r = -0.44, and the influence of the HTI was at the level of r = -0.34. For middle-early hybrids the sum of effective temperatures (≥ + 10° C) in May and June r = -0.46 and r = -0.28, respectively, and also the sum of effective temperatures (≥ + 10° C) in August – r = 0.18 had a strong effect. However, for medium-maturing maize hybrids, the duration of the growing season was determined by the sum of effective temperatures (≥ + 10° C) for May, June and July – r = -0.37, r = -0.34 and r = -0.28, and the sum of effective temperatures (≥ + 10° C) in August – r = 0,18. It is also possible to note the influence and the total sum of effective temperatures (≥ + 10° C) during vegetation at the level of correlation coefficient r = -0.51. According to the research results of mathematical models of the influence of weather conditions on the formation of phenotypic productivity of maize hybrids of different maturity groups both general biological regularities and group differences of features formation were established. Thus, if we analyze the differences between groups of early-ripening and middle-early corn hybrids, their growth and development in general are influenced by the sum of the effective temperatures, rainfall and HTI. In fact, the studied groups of ripeness differ slightly and the main differences are observed only in the variability of the studied features or their close relationship with each other. However, middle-aged hybrids respond somewhat differently to environmental factors, which allow developing the elements of adaptive growing technology for each of the maturity groups. Key words: corn, hybrid, phenotype, mathematical model, productivity, economic and valuable features.

Phenological Phases

<p>The duration of phenological phases of 1-7-yeats-old <em>Hyssopus</em><em> officinalis</em> and its seasonal rhythms depending on the abiotic conditions of growth are established. It has been proved that hyssop belongs to late species by the terms of regrowth, the spring phase of which begins with the establishment of stable heat in April-May. The hyssop is attributed to the summer flowering plants, the flowering is the longest phase, and mass flowering is registered in July-August. Hyssop is a spring-summer-autumn-green plants, which begin the vegetation in spring, and in autumn they stay under the snow in green. Climatic conditions during the years of research were marked by temperature and precipitation fluctuations that affected the duration of the growing season and individual phenophases. First year seedlings of H. officinalis had the period of intensive growth and development from sowing to a period of rest was 159 days, whereas in Zhytomyr Polissya the sum of active temperatures was 2610 °С and sum of effective temperatures – 1180 °С. For 2-7-year-old hyssops the period from the spring regeneration to the death of the blooming plants and the formation of seeds lasted an average for 144 days (from 133 days in 2010 to 147 days in 2014). The range of temperatures required for the entire period was insignificant: active - from 2548.2 °C (2011) to 2696.3 °C (2012); effective - from 1152 °C (2009) to 1402.2 °C (2010). Compared with other phenological phases during the blooming period, plants require considerably more heat. The water scarcity did not affect significant on the duration of H. officinalis season rhythms. It is shown that to complete the development cycle of H. officinalis from the total amount of active temperatures was spent on average: for germination of seeds and spring regrowth – 5.9%, for stem formation phase – 13.5%, budding – 22.11%, blooming – 29.5%, fruiting – 16.5%, seeds maturation and pedicels dying – 12.6%; effective temperatures, respectively - 5.2%, 11.9%, 22%, 32.6%, 17.7%, 10.5%. The climatic conditions of Ukrainian Polissya allow to obtain hyssop plant raw material during one growing season, that indicates the adaptation of the species to the new conditions of growth.                </p>

Purpose. The aim of the study was to identify samples of chickpeas with economically valuable traits on the ground of the basic collection of parent material as a source of traits for breeding in conditions of the Right-Bank Forest-Steppe of Ukraine; to systematize them by yielding capacity, elements of crop structure, duration of the growing season, morphological features, areas of use in accordance with the two main groups of culture morphotypes – kabuli and desi – in order to plan areas of breeding. Methods. Field (conducting phenological observations), laboratory (assessment of the studied material). Results. 223 samples of chickpeas originating from different countries of Asia and Europe were screened in order to determine their breeding value in conditions of the Right-Bank Forest-Steppe of Ukraine. It is established that promising for selection in such conditions are samples originating from Russia, Syria and India, as well as varieties and new highperformance lines obtained from Plant Breeding and Genetics Institute – National Center of seed and cultivar investigation of NAAS of Ukraine, characterized by a set of features such as grain productivity (number of beans per plant, weight of 1000 seeds and others), and suitability for the mechanized harvesting (height of the plant, height of attachment of the lower bean and others). The studies were conducted in contrasting conditions of two years, 2018 and 2019, which differed significantly in the amount of precipitation and the sum of effective temperatures, and the nature of their distribution during the growing season, which allowed to obtain more objective information about breeding material. The nature of variability of the main economically valuable traits by groups of morphotypes as well as correlations between them is determined, this will allow to make targeted selections in breeding for the above mentioned traits, using this experimental material as genetic sources. Conclusions. A set of chickpea samples of different ecological and geographical origin with valuable breeding traits have been identified, which can be used as genetic sources in practical selection to create new varieties with specified parameters in conditions of the Right-Bank Forest-Steppe of Ukraine. The selected sources were unique in one feature as well as combined a set of features.
