Purpose. Evaluation of collection samples of the genus Calendula L. available at the Experimental station of medicinal plants (ESMP) for the levels of display of morphological characters in order to identify the reference varieties and form a collection of standards. Methods. Field, laboratory, mathematical and statistical ones. Results. During 2012–2014 years the collection of the genus Calendula L. was evaluated, that includes 145 samples of 4 species from 18 countries, for the eight morphological characters (plant height, inflorescence number, full inflorescence number, the color of ligulate and tubular florets, number of rows of ligulate florets, inflorescence diameter, disk diame­ter) and varieties were distributed by the level of manifestation according to current technique for distinctness, uniformity and stability (DUS). Conclusions. Samples of marigold were identified that can be sources of standards or starting material by plant height, inflorescence number, inflorescence full number, color of ligulate and tubular florets, number of rows of ligulate florets, inflorescence diameter, disk diameter and by all degree of their manifestation. For the highest level of manifestation of character complex (inflorescence diameter, disk diameter, the number of rows of ligulate florets, inflorescence full number and their manifestation pattern) ‘Mandarin Twist’ variety appeared to be the best

Purpose. Conduct a generalized assessment of samples of the base collection of hops Humulus lupulus L. Institute of Agriculture Polissia of NAAS of Ukraine according to the level of manifestation of the main morphological characters to highlight domestic varieties with reference characters.Methods. Field, visual estimation, laboratory, analytical.Results. During 2011–2017 samples of the base collection of Humulus lupulus L. hops were evaluated in the conditions of Polissia; the level of manifestation of their main morphological characters was determined. An information base has been formed on the morphological characteristics of hop varieties with a list of foreign standard varieties and domestic applicants for standards on certain characteristics. It was revealed that breeds have varying degrees of characters manifestation. In particular, according to the intensity of the anthocyanin color of the stem from very weak – ‘Slavianka’, ‘Zahrava’ to very strong – ‘Hranit’; according to the color of the upper part of the leaf blade: from yellow-green, characteristic for the ‘Alta’ and ‘Khmeleslav’ varieties to green, for the ‘Zahrava’ and ‘Clon 18’ varieties. By flowering time and onset of technical ripeness of cones, the varie­ties are divided into groups: early – ‘Alta’, medium – ‘Clon 18’, ‘Zahrava’, later – ‘Xanta’, ‘Haidamatskyi’, ‘Hranit’. Among domestic applicants for standards in the form of a bush, the variety ‘Zmina’ – spindle-shaped, ‘Slavianka’ – cylindrical, ‘Alta’ –conical, and others; in the shape of a cone – variety ‘Clone 18’ – cylindrical, ‘Slavianka’ – narrow oval, ‘Ruslan’, ‘Alta’ – oval, ‘Zlato Polissia’ – wide oval and ‘Zhytych’ – spherical.Conclusions. Based on the results of long-term investigations, a comparative assessment of the reference varieties of foreign breeding and samples of the collection of domestic origin was carried out according to the characteristics of the vegetative (stem, leaf, bush), plant generative organs (cone) and phenological descriptions (time of flowering and cone harvesting), which allowed to determine the varieties with stable manifestation of the main identification signs of hops. Domestic varieties that are carriers of individual (‘Zlato Polissia’, ‘Zhytych’, ‘Ruslan’, ‘Poliskyi’) or several traits (‘Slavianka’, ‘Zahrava’, ‘Haidamatskyi’, ‘Clon 18’, ‘Khmeleslav’, ‘Alta’, etc.) are isolated and proposed for use as standards. | Цель. Провести обобщенную оценку образцов базовой коллекции хмеля Humulus lupulus L. Института сельського хозяйства Полесья НААН (ИСГП НААН) по уровню проявления основных морфологических признаков для выделения отечественных сортов с эталонными признаками. Методы. Полевой, визуальной оценки, лабораторный, аналитический. Результаты. В течение 2011–2017 гг. была проведена оценка образцов базовой коллекции хмеля Humulus lupulus L. в условиях Полесья, определен уровень проявления ихних основных морфологических признаков. Сформирована информационная база морфологических признаков сортов хмеля с перечнем иностранных сортов-стандартов и отечественных претендентов на стандарты по определенным признакам. Установлено, что сорта имеют различную степень выявления признаков. В частности, по интенсивности антоциановой окраски стебля от очень слабого – ‘Слов’янка’, ‘Заграва’ к очень сильному – ‘Граніт’; по окраске верхней части листовой пластинки: от желто-зеленой, характерной для сортов ‘Альта’ и ‘Хмелеслав’ к зеленой – для сортов ‘Заграва’ и ‘Клон 18’. По времени цветения и наступления технической спелости шишек сорта распределены по группам: ранние – ‘Альта’, средние – ‘Клон 18’, ‘Заграва’, поздние – ‘Ксанта’, ‘Гайдамацький’, ‘Граніт’. Среди отечественных претендентов на эталоны по форме куста предложено сорт ‘Зміна’ – веретенообразная, ‘Слов’янка’ – цилиндрическая, ‘Альта’ – коническая и др.; по форме шишки – сорт ‘Клон 18’ – цилиндрическая, ‘Славянка’ – узкоовальная, ‘Руслан’, ‘Альта’ – овальная, ‘Злато Полісся’ – широкоовальная и ‘Житич’ – шаровидная. Выводы. По результатам многолетних исследований проведена сравнительная оценка сортов-эталонов иностранной селекции и образцов коллекции отечественного происхождения по характеристикам вегетативных (стебель, лист, куст), генеративных органов растений (шишка) и фенологическим описаниям (время цветения и сбора шишек), что позволило определить сорта со стабильным проявлением основных идентификационных признаков хмеля. Выделены и предложены для использования в качестве эталонов отечественные сорта, которые являются носителями отдельных признаков (‘Злато Полісся’, ‘Житич’, ‘Руслан’, ‘Поліський’) или нескольких (‘Слов’янка’, ‘Заграва’, ‘Гайдамацький’, ‘Клон 18’, ‘Хмелеслав’, ‘Альта’ и др.). | Мета. Оцінити зразки базової колекції хмелю звичайного (Humulus lupulus L.) Інституту сільського господарства Полісся НААН (ІСГП НААН) за рівнем прояву основних морфологічних ознак для виділення вітчизняних сортів з еталонними ознаками.Методи. Польовий, візуального оцінювання, лабораторний, аналітичний.Результати. Упродовж 2011–2017 рр. проведено оцінювання зразків базової колекції хмелю звичайного (Humulus lupulus L.) в умовах Полісся, визначено рівень прояву їхніх основних морфологічних ознак. Сформовано інформаційну базу морфологічних ознак сортів хмелю з переліком іноземних сортів-еталонів та вітчизняних претендентів в еталони за певними ознаками. Сорти мають різний ступінь виявлення ознак. Зокрема, за інтенсивністю антоціанового забарвлення стебла: від дуже слабкого – ‘Слов’янка’, ‘Заграва’ до дуже сильного – ‘Граніт’; за забарвленням верхньої частини листкової пластинки: від жовто-зеленого забарвлення, характерного для сортів ‘Альта’ та ‘Хмелеслав’ до зеленого – для сортів ‘Заграва’ та ‘Клон 18’. За часом цвітіння та настанням технічної стиглості шишок сорти розподілено за групами: ранні – ‘Альта’, середні – ‘Клон  18’, ‘Заграва’, пізні – ‘Ксанта’, ‘Гайдамацький’, ‘Граніт’. Серед вітчизняних претендентів в еталони за формою куща запропоновано сорт ‘Зміна’ – веретеноподібна, ‘Слов’янка’ – циліндрична, ‘Альта’ – конічна та ін.; за формою шишки – сорт ‘Клон 18’ – циліндрична, ‘Слов’янка’ – вузько-овальна, ‘Руслан’, ‘Альта’ – овальна, ‘Злато Полісся’ – широкоовальна та ‘Житич’ – куляста.Висновки. За результатами багаторічних досліджень проведено порівняльне оцінювання сортів-еталонів іноземної селекції та зразків колекції вітчизняного походження за характеристиками вегетативних (стебло, листки, кущ) і генеративних органів рослин (шишка) та фенологічними описами (час цвітіння і збирання шишок), що дозволило визначити сорти зі стабільним проявом основних ідентифікаційних ознак хмелю. Виділено та запропоновано для використання у ролі еталонів вітчизняні сорти, які є носіями окремих ознак (‘Злато Полісся’, ‘Житич’, ‘Руслан’, ‘Поліський’) або декількох (‘Слов’янка’, ‘Заграва’, ‘Гайдамацький’, ‘Клон 18’, ‘Хмелеслав’, ‘Альта’ та ін.).
