Мета. Pозкрити сировинний потенціал інтродукованих у Національному ботанічному саду імені М. М. Гришка НАН України (НБС) представників роду Paeonia L. за вмістом біологічно активних сполук. Методи. Об’єктом досліджень слугували інтродуковані рослини роду Paeonia: півонія молочноквіткова (P. lactiflora Pall.), півонія лікарська (P. officinalis L.) та її гібридні форми: P. officinalis ‘Rubra Plena’, F1 (P. officinalis ‘Rubra Plena’ ´ P. peregrina Mill.), сорт селекції НБС ‘Квазімодо’ [P. lactiflora ‘M-lle Jeanne Riviere’ ´ F1 (P. officinalis ‘Rubra Plena’ ´ P. peregrina)], півонія незвичайна (P. anomala L.). Методами спектрофотометрії, титриметрії і колориметрії визначали вміст поліфенольних сполук, гомополісахаридів, аскорбінової кислоти та інших речовин. Аналіз біологічно активних сполук проводили методом високоефективної рідинної хроматографії ВЕРХ (HPLC). Результати. Зафіксовано видові й сортові відмітності в кількості поліфенолів у рослинах різних видів та форм. Установлено, що корені досліджуваних рослин F1 (P. officinalis ‘Rubra Plena’ ´ P. peregrina), сорту селекції НБС ‘Квазімодо’, P. lactiflora містять набагато більшу кількість полісахаридів порівняно з коренями P. аnomala. У рослинах півонії середня частка вітаміну С становить 37,65% та варіює між представниками роду в межах від 22,10 ± 2,18 [F1 (P. officinalis ‘Rubra Plena’ ´ P. peregrina)] до 47,60 ± 3,69 (P. anomala) і 49,30 ± 5,50% (P. lactiflora). Максимальний уміст каротиноїдів зафіксовано у коренях P. officinalis ‘Rubra Plena’ (2,10 ± 0,21 мг%) і F1 (P. officinalis ‘Rubra Plena’ ´ P. peregrina) (2,20 ± 0,13 мг%). Значна кількість вільної галової кислоти спостерігається в коренях P. anomala, галотанінів – у P. lactiflora. Висновки. Результати фітохімічних досліджень рослин видів, гібридів та сортів роду Paeonia, інтродукованих у Національному ботанічному саду ім. М. М. Гришка НАН України, показали, що вони накопичують значний уміст основних біологічно активних сполук: флавоноїдів, дубильних речовин, моно- та полісахаридів, пігментів. Перспективними за комплексом діючих речовин є корені P. lactiflora та P. officinalis, яких у них набагато більше, ніж у P. anomala. Створені на основі цих видів гібридні форми P. officinalis ‘Rubra Plena’, F1 (P. officinalis ‘Rubra Plena’ ´ P. peregrina) і сорт ‘Квазімодо’, не поступаються видам за вмістом фенольних сполук, цукрів, пігментів та аскорбінової кислоти. Частка пеоніфлорину в коренях становить для P. lactiflora (1,95%), P. anomala (1,09%), P. officinalis ‘Rubra Plena’ (0,95%), P. officinalis (0,78%). Досліджені види, гібриди та сорти пропонуються для вирощування в культурі з метою заготівлі лікарської сировини як джерела біологічно активних сполук з можливістю доповнення, а то й заміни офіційного виду півонії незвичайної (P. anomala).

Purpose. To reveal the peculiarities of the seasonal rhythm of growth and development of Itoh Group peony cultivars in the conditions of the M. M. Hryshko National Botanical Garden National Academy of Sciences of Ukraine. Methods. The objects of research were plants of 24 cultivars of Itoh Group peonies. The research was conducted on the experimental field of the Department of Flowering and Ornamental Plants of the M. M. Hryshko National Botanical Garden National Academy of Sciences of Ukraine during 2017–2020. The sum of effective temperatures was calculated by summing the daily air temperatures reduced by the biological zero. Results. The phenological phases of Ito Group cultivars growth were determined. Phenological spectra for different groups are presented. It was determined that the flowering of early cultivars: ‘First Arrival’, ‘Hillary’, ‘Julia Rose’, ‘Morning Lilac’, ‘Old Rose Dandy’, ‘Sonoma Apricot’ starts at the sum of effective temperatures ≥ 400 °С. The middle group hybrids bloom when the sum of temperatures reaches 450 °С. This group includes: ‘Bartzella’, ‘Callie’s Memory’, ‘Cora Louise’, ‘Lollipop’, ‘Scarlet Heaven’, ‘Sonoma Velvet Ruby’, ‘Yellow Dream’, ‘Yellow Emperor’, ‘Yellow Heaven’, ‘Yellow Waterlily’. Late flowering group includes: ‘Border Charm’, ‘Garden Treasure’, ‘Kopper Kettle’, ‘Pastel Splendor’, ‘Prairie Charm’, ‘Viking Full Moon’, ‘White Emperor’, ‘Yankee Doodle Dandy’; accumulation of effective temperatures above 500 °С is an essential requirement for their flowering. Conclusions. Itoh Group cultivars successfully pass all phases of seasonal development and manage to complete the growing season. Cultivars belong to the spring-summer-autumn-green phenorhythmotype. The onset of the corresponding phenological phases in peonies of the studied group of cultivars requires a certain sum of effective temperatures. Plant outgrowth begins on March 23 – April 2, when the sum of effective temperatures ranges from 20–40 °С. The flowering of varieties characterized as late spring, lasts 6–9 days ± 3–4 days, depending on the varietal characteristics and the year of cultivation. A rapid increase in the sum of effective temperatures up to 700 °C shortens the flowering phase by 4–5 days. An assortment of early (May 22–25 ± 2–3 days), medium (May 26–28 ± 3–5 days) and late-flowering (May 29–31 ± 4–6 days) cultivars has been selected, what ensures the continuity of peony flowering during two months.

Установити особливості сезонного ритму росту й розвитку сортів півоній Itoh Group в умовах Національного ботанічного саду імені М. М. Гришка НАН України (НБС).Методи. Об’єктом досліджень слугували рослини 24 сортів півоній Itoh Gp. Дослідження проводили на експериментальній ділянці відділу квітниково-декоративних рослин НБС протягом 2017–2020 рр. Суму ефективних температур обраховували через сумування добових температур повітря, зменшених на значення біологічного мінімуму.Результати. Виділено фенологічні фази росту й розвитку рослин півоній Іто-групи. Побудовано фенологічні спектри для різних феногруп. Установлено, що цвітіння ранніх сортів – ‘First Arrival’, ‘Hillary’, ‘Julia Rose’, ‘Morning Lilac’, ‘Old Rose Dandy’, ‘Sonoma Apricot’ – розпочинається за суми ефективних температур ≥ 400 °С. Сорти рослин середньої групи зацвітають, коли сума температур сягає 450 °С. До цієї групи належать ‘Bartzella’, ‘Callie’s Memory’, ‘Cora Louise’, ‘Lollipop’, ‘Scarlet Heaven’, ‘Sonoma Velvet Ruby’, ‘Yellow Dream’, ‘Yellow Emperor’, ‘Yellow Heaven’, ‘Yellow Waterlily’. Пізньоквітуюча група включає сорти ‘Border Charm’, ‘Garden Treasure’, ‘Kopper Kettle’, ‘Pastel Splendor’, ‘Prairie Charm’, ‘Viking Full Moon’, ‘White Emperor’, ‘Yankee Doodle Dandy’, необхідною умовою цвітіння яких є накопичення ефективних температур понад 500 °С.Висновки. Рослини сортів півоній Itoh Gp успішно проходять усі фази сезонного розвитку та встигають завершити вегетацію. За тривалістю вегетації вони належать до весняно-літньо-осінньозеленого феноритмотипу. Настання відповідних фенологічних фаз у півоній досліджуваної групи сортів потребує певної суми ефективних температур. Відростання сортів розпочинається 23 березня – 2 квітня, коли сума ефективних температур змінюється в межах 20–40 °С. Цвітіння сортів характеризується як пізньовесняне, триває 9–16 діб ± 3–4 доби й залежить від сортових особливостей рослин та року вирощування. Швидке наростання суми ефективних температур до 700 °C під час цвітіння рослин скорочує його тривалість на 4–5 діб. Аналіз фенологічних спектрів сезонного розвитку рослин дав змогу виділити сортимент ранньо‑ (22–25 травня ± 2–3 доби), середньо‑ (26–28 травня ± 3–5 діб) та пізньоквітуючих (29–31 травня ± 4–6 діб) півоній Itoh Gp, що забезпечує безперервність їхнього цвітіння загалом упродовж двох місяців.

Purpose. Reveal the features of the formation of a quali­ty indicator complex in winter bread wheat depending on the growing seasons, preceding crops and sowing dates, as well as differentiate and identify genotypes with high and stable levels of manifestation. Methods. Field, laboratory, statistical. Results. A different share of the influence of the year conditions, the preceding crop, the sowing date and their interactions on the quality indicators of some varie­ties was determined. A different reaction of varieties in terms of quality indicators, depending on the investigated factors was revealed. The variation was very low for test weight, water absorption ability of flour, crumb porosity. Strong variation was observed for flour strength after sunflower and soybean as preceding crops, alveograph configuration ratio after sunflower and soybean, index of elasticity dough after corn, valorimetric value after mustard, dough dilution degree after green manure, sunflower, corn and especially after mustard and soybeans. The varieties, which on average for 2016/17–2018/19 reliably exceeded the standard both in individual indicators and in general in terms of physical indicators of grain and flour quality and dough rheological properties. GYT biplot analysis identified the genotypes ‘MIP Vidznaka’ and ‘MIP Assol’ with a more optimal combination of increased yield and a complex of quality indicators in terms of different years, preceding crops and sowing dates. Some varieties, namely, ‘Estafeta myronivs’ka’, ‘Trudiv­nytsia myronivs’ka’, ‘MIP Valensiia’, ‘MIP Yuvileina’, ‘Balada myronivs’ka’, ‘Vezha myronivs’ka’ were inferior to them, but were significantly superior the others. Conclusions. The selected by quality indicators varieties as genetic sources can be used in breeding process. A more stable level of yield and quality indicators at different sowing dates after different preceding crops should be expected for growing varieties ‘MIP Vidznaka’, ‘MIP Assol’, as well as ‘Estafeta myronivs’ka’, ‘Trudivnytsia myronivs’ka’, ‘MIP Valensiia’, ‘MIP Yuvileina’, ‘Balada myronivs’ka’, ‘Vezha myronivs’ka’. The peculiarities obtained in the research should be taken into account when evaluating and differentiating genotypes in breeding process, as well as developing basic elements of technology for growing the varieties of winter bread wheat.

The energy value of plants was determined using an IKA C-200 calorimeter. The obtained results were analysed statistically. Results. The height of plants varied from 140.9 (Genotype 1) to 157.5 (Genotype 5) cm, stem diameter from 11.67 (Genotype 1) to 16.1 (Genotype 6) mm, the number of internodes from 18.7 (Genotype 1) to 25.7 (Genotype 6), the number of leaves on a stem from 14.11 (Genotype 1) to 21.8 (Genotype 5), leaf lamina length from 14.2 (Genotype 1) to 23.45 (Genotype 6) cm, leaf lamina width from 6.34 (Genotype 1) to 14.5 (Genotype 4) cm, inflorescence length from 27.4 (Genotype 1) to 45.4 (Genotype 3) cm, inflorescence width from 2.32 (Genotype 1) to 4.92 (Genotype 3) cm, and the number of stems from 2.55 (Genotype 2) to 5.33 (Genotype 1). The study of the content of structural and functional compounds and nutrients at the flowering stage showed that the dry matter content was in the range of 13.58–16.00%, sugars 5.07–8.86%, titratable acidity 3.28–4.25%, lipids 3.33–6.61%, ascorbic acid 382.83–693.82 mg%, b-carotene 0.94–3.48 mg%, ash 6.79–9.2%, calcium 1.00–2.44%, phosphorus 1.61–2.67% and energy value 3337.0–3498.0 cal/g. Conclusions. It was revealed that samples of various genotypes of B. orientalis are a valuable source of nutrients at the flowering stage. The biochemical composition of plants depended on the genotype and stage of growth. Results of the morphometric study showed variability of investigated parameters. The obtained data can be used to predict and evaluate the results of introduction and breeding studies with B. orientalis genotypes as promising crops in Ukraine.

Purpose. Determine the ecological plasticity and productivity of F1 sunflower hybrids created on the basis of maternal and parental lines, selected according to an accelerated selection system of lines resistant to herbicides (imidazoline and sulfonylurea groups) and broomrape (Orobanche cumana Wallr.). Methods. Statistical analysis of F1 sunflower hybrids was carried out using the methods of variation statistics, regression and analysis of variance using the Microsoft Office Excel 2016 application package. Molecular biological, biotechnological and classical selection methods were used for the accelerated system of line selection. Thus, for the purpose of targeted selection of sunflower sterility fixers, we used HRG01 molecular SCAR marker to identify the gene for the restoration of pollen fertility (Rf1). To accelerate the creation of parental lines resistant to tribenuron-methyl, we used a culture of immature embryos in vitro. Results. The results of testing of F1 sunflower hybrids at Kyiv, Chernihiv, Cherkasy (Uman and Shpolianskyi districts), Khmelnytskyi, Kharkiv, Kherson and Odesa regions. The hybrids were created on the basis of selected lines, chosen according to an accelerated selection system for herbicide-resistant lines (imidazoline (IMI-hybrids) and sulfonylurea (SU-hybrids) groups) and broomrape (Orobanche cumana Wall). The standards for comparison with hybrids were: for IMI hybrids – hybrids ‘NK Neoma’ (Syngenta) and ‘ES Genesis’ (Euralis), and for SU-hybrids – ‘SY Sumiko’ (Syngenta) and ‘P64LE25’ (Pioneer). As a result, it was found that among SU-hybrids, UA 2/106 had a 3.9% higher yield when compared to the standards (‘SY Sumiko’ and ‘P64LE25’). And for IMI-hybrids it was found that hybrids UA 1/67, UA 1/66, UA 1/84 have the same yield of 2.76 t/ha as the ‘NK Neoma’ standard. IMI hybrids UA 1/92, UA 1/102 have the same yield of 2.91 t/ha as ‘ES Genesis’. Conclusions. F1 hybrids were created on the basis of the original breeding material selected due to the accelerated system of sunflower lines selection. The hybrids were analyzed according to the yield indicator. The most productive among the tested SU-hybrids was UA 2/106 hybrid, among the IMI hybrids – UA 1/67, UA 1/66, UA 1/84, UA 1/92 and UA 1/102.

Purpose. To reveal the features of agrobiological parameters formation of sweet sorghum various varieties and hybrids in the conditions of the Right-Bank Forest-Steppe of Ukraine. Methods. During 2018–2020 twenty-one varieties and hybrids of sweet sorghum of various ecological and geographical origins (Ukraine, Russia, USA, France, Germany, Hungary, Brazil) were studied in the field. Parameters like plant height and indices of their individual productivity (grain weight per panicle, 1000 grain weight, etc.), yield of dry biomass and grain, content of sugar in juice and protein in grain, as well as estimated sugar and protein yield in a crop. The counts were carried out in the phase of physiological ripeness of the culture. Results. In the group of Ukrainian varieties and hybrids, the plants were from 272 to 306 cm high, in the foreign group – from 274 to 412 cm. Varieties ‘Red Amber’, ‘Sioux’, ‘Affas CJ 899’, ‘Freed’ and ‘Early Orange’ are of high value for breeding practice, their plants were the tallest – from 388 to 412 cm. The panicle length of sweet sorghum cultivars of Ukrainian breeding ranged from 16.0 to 17.3 cm, foreign – from 11.0 to 19.4 cm. Grain weight from one panicle varied from 32.8 to 41.6 g and from 29.2 to 43.5 g, respectively. In a wide range, depending on the varietal characteristics, the indicator of the number of grains per panicle also varied from 1338 to 1708 pcs. The mass of 1000 grains of sweet sorghum ranged from 28.0 to 31.0 g in varieties and hybrids of Ukrainian breeding, in foreign ones – from 19.3 to 31.0 g. The yield of dry vegetative mass of cultivars of Ukrainian breeding was at the level of 8.24–9.11 t/ha. The highest rates were shown in hybrid ‘Mamont’ and ‘Huliver’ variety – 9.05 and 9.11 t/ha, respectively. For cultivars and hybrids of foreign breeding, this indicator varied from 7.00 to 12.17 t/ha. Significantly higher biomass in comparison with the standard variety (‘Sylosne 42’) was produced by ‘Vorai Sumac’, ‘Sorgo Cucre’, ‘Sioux’, ‘Freed’, ‘Red Amber’, ‘Mohavk’, ‘Affas CJ 899’, ‘Early Orange’ – 9.03–12.17 t/ha. The sugar content in sweet sorghum juice varied from 15.2 to 17.2%. The estimated sugar yield in Ukrainian cultivars was at the level of 0.82–0.89 t/ha, in foreign ones – from 0.72 to 1.18 t/ha. In all studied varieties it was the highest in ‘Sorgo Cucre’, ‘Sioux’, ‘Freed’, ‘Red Amber’, ‘Mohavk’, ‘Affas CJ 899’, ‘Early Orange’ – 0.94–1.18 t/ha. Conclusions. The productivity of sweet sorghum varies greatly depending on the origin of the variety and hybrid. In the conditions of the Right-Bank Forest-Steppe, in order to obtain a high sugar yield, it is advisable to grow ‘Sylosne 42’, ‘Favoryt’, ‘Troistyi’, ‘Dovista’, ‘Huliver’ varieties and ‘Ananas’, ‘Medovyi’, ‘Mamont’ hybrids. Varieties ‘Vaconia Orange’, ‘Vorai Sumac’, ‘Sorgo Cucre’ and hybrids ‘Ald Sorghum’, ‘Sioux’, ‘Freed’, ‘Red Amber’, ‘Mohavk’, ‘Affas CJ 899’, ‘Early Orange’ provide high yields of vegetative masses. Hybrids ‘Freed’, ‘Affas CJ 899’ and ‘Early Orange’ produce a large vegetative mass (11.08–12.17 t/ha), grain yield (8.00–8.15 t/ha) and a high protein content (9.8–11.3%).

Purpose. Grapevines (Vitis spp.) are affected by many viral diseases which cause serious pathological problems. GLRaV-3 is among the most widespread leafroll viruses, while Grapevine Fanleaf Virus (GFLV) is a destructive pathogen which reduces the lifespan of grapevine. Considering the impact and the spread of these diseases, our objective was to analyse the presence of these two viruses in several grapevine varieties in grapevine collection at ATTC Vlore. Data gathered from plant pathogens serve to better understand and prevent the spread of pathogens, as a mandatory rule for the quality control of certified plant material during vegetative propagation. Method. The presence of two common viruses were tested using virus specific primers; LC1/LC2 primer pair designed from the hHSP70 gene for detecting Grapevine Leafroll-associated Virus-3 (GLRaV3) and C3390/H2999 primer pair, designed from coat protein coding regions for detecting Grapevine Fanleaf Virus (GFLV), in six varieties; ‘Merlot’, ‘Kallmet’, ‘Shesh i zi’, ‘Shesh i bardhё’, ‘Debinё’, and ‘Pulёz’, provided through a randomised sampling procedure. One Step Reverse Transcription Polymerase Chain Reaction assay was used to detect the viral presence. Results showed a high (100%) prevalence of GLRaV3 virus in all of analysed samples, as the most frequent among the two pathogens. Analysis for of GFLV virus showed low infection rate, being present in only one sample. Conclusions. We herein show an efficient, fast and reproducible method for detecting grapevine viruses through one step RT-PCR. Our results suggest that sampling of the infected plant material should be avoided due to the presence of viral infections.

Purpose. The objective of this study was to evaluate the morphological parameters of Lycium spp. seeds from the collections in M. M. Hryshko National Botanical Garden (NBS) NAS of Ukraine. Methods. Cultivars and varieties of three Lycium species (Lycium barbarum, L. chinense, L. truncatum) were studied in the period from 2016 till 2019. The following morphometric measurments were conducted: seeds weight, seeds length, seeds width and index of seeds shape. Basic statistical analyses were performed using PAST 2.17. Hierarchical cluster analyses of similarity between genotypes were computed on the basis of the Bray-Curtis similarity index. Correlation between traits was determined using the Pearson correlation coefficient. Results. Cultivars and varieties of different species of Lycium varied in weight, shape, and size of seeds. Seed weight varied from 0.54 to 3.54 mg, seed length from 1.90 to 3.06 mm, seed width from 1.43 to 2.53 mm. The shape indexes of seeds were found ranging from 0.73 to 0.80. The analysis of coefficient of variation showed the difference of variability in morphometric characteristics between some Lycium spp. cultivars and varieties. The most variable features: seeds weight (8.51–28.22%) and seeds length (5.07–24.81%) are important parameters for selection. The use of cluster analysis made it possible to establish the similarity between the species of the studied Lycium species. Conclusions. Diagnostic signs by seed morphometry for differentiation of Lycium species were revealed. The analysis of coefficient of variation showed the difference of variability in morphometric characteristics between some Lycium cultivars and varieties. The most variable characteristics of the studied genotypes were seed weight and length, which are important parameters for selection because they determine the pulp content and number of seeds, as well as the ratio of these parameters between them. It is through variability that promising varieties with low seed weight and length can be selected, Due to securing them later vegetatively.

Оцінити морфометричні показники насіння Lycium spp. колекції Національного ботанічного саду імені М. М. Гришка (НБС) НАН України.Методи. Упродовж 2016–2019 рр. досліджено 21 генотип (10 сортів і 11 форм) трьох видів (Lycium barbarum, L. chinense, L. truncatum). Установлено морфометричні показники насіння (маса, довжина, ширина та індекс форми). Статистичний аналіз виконували за допомогою PAST 2.17. Ієрархічний кластерний аналіз подібності генотипів здійснено за індексом подібності Брей-Кертіса. Наявніть зв’язків між параметрами встановлювали за коефіцієнтом кореляції Пірсона.Результати. Сорти та форми різних видів рослин Lycium варіювали за масою, розміром та формою насіння. Морфометричні параметри насіння були такими: маса – від 0,54 до 3,54 мг, довжина – від 1,90 до 3,06 мм, ширина – від 1,43 до 2,53 мм. Величина індексу форми насіння становила від 0,73 до 0,80. Аналіз коефіцієнта варіації показав різну мінливість морфометричних характеристик сортів та форм різних видів Lycium. Наймінливішою є маса насіння (8,51–28,22%) та його довжина (5,07–24,81%), які є важливими параметрами для селекції. Використання кластерного аналізу дало змогу встановити генетичні зв’язки між сортами й формами Lycium та розподілити їх у два основних кластери.Висновки. Виявлено діагностичні ознаки морфометричних параметрів насіння для ідентифікації видів Lycium. Аналіз коефіцієнта варіації показав мінливість морфомет­ричних характеристик між деякими сортами та формами Lycium. Наймінливішими параметрами досліджуваних генотипів були маса та довжина насіння. Останні є важливими для селекції, оскільки від них залежить уміст м’якушу та кількість насіння, а також співвідношення цих параметрів між ними. Завдяки мінливості можна дібрати перспективні сорти з невеликими масою та довжиною насіння, закріпивши їх потім вегетативно.
