Purpose. To study the influence of agriecological conditions of edaphic-climatic macro- and microzones on adap­tability and productivity of new soft winter wheat, identification and selection of complementary varieties for appropriate conditions. Methods. Field, laboratory, analytical and statistical ones. Results. Peculiarities of the formation of productivity of varieties and its stability cultivation on the condions of cultivation in edaphic-climatic zones, subzones and microzones, including favourable and unfavou­rable years were studied. For realizing the potential of their productivity, it is advisable to introduce a differentiated approach to their cultivation in agri-climatic zones, subzones, microzones according to the requirements of biological characteristics of varieties, their natural adaptive capacity, natural and ecological environment of these zones. Complementary varieties were identified and recommended for use in edaphic-climatic zones, subzones and microzones that demonstrated high plasticity, better adaptability to favourable agri-ecological factors and were more tolerant and resistant to adverse ones. Conclusions. According to the set of productivity and ecological plasticity indices, it is desirable to cultivate varieties Sotnytsya, Kalancha, Hurt, Tonatsiya, Dobrochyn, Gubernator Donu in the Steppe zone; Sotnytsya, Oriyka, Lira Odeska, Tatsitus and Fidelius – in the Forest-Steppe; Tatsitus, Fidelius, Sailor, Etela – in the Polissia.

Purpose. Substantiating the selection of potato varieties for their ecological plasticity and stability to grow in Polissia. Methods. Field, laboratory, analitycal and statystical ones. Results. Impact of weather conditions during the growing season on the stability of potato varieties was estimated by indicators of yield, starch content and collection over the years by determining the average, standard deviation, minimum, maximum values and range of variation. ‘Memphis’, ‘Faluka’, ‘Arsenal’ and ‘Evolution’ were distinguished from the studied potato varieties by high genetic stability – their deviation from the average variance marked «minus» had values that were significantly less than zero. ‘Faktor’, ‘Flamenko’ and ‘Evora’ varieties are plastic (deviation is close to ±0), ‘Kolomba’, ‘Arizona’ and ‘Voliumiia’ ones – very plastic (deviation is most distant from zero). The studied varieties were distributed by homeostasis as follows: ‘Arizona’, ‘Colombo’, ‘Factor’ and ‘Memphis’ are the most valuable. Conclusions. ‘Evora’ potato variety can be considered intensive in terms of yield. ‘Evolution’ and ‘Flamenco’ varieties formed stable yields, during the years of study the difference between their maximum and minimum yields was the least – 8.2 and 9.3 tons per ha, respectively. Environmental assessment according to Eberhart and Russell indicates a high genetic stability of such potato varieties as ‘Arizona’, ‘Volyumiia’, ‘Kolombo’, ‘Evora’ and ‘Flamenko’. Conditions of Zhytomyr Oblast Plant Varieties Studying Centre are the most favorable among the studied regions to cultivate potato varieties.

Purpose. Identifying new scab-resistant apple varieties with high biological potential by the set of agronomic characters and the ability to realize it effectively in various soil and climatic conditions. Methods. Field, laboratory, comparison, generalization, statistical ones. Results. The author presents the results of study of 17 scab-resistant non-irrigated apple varieties on a semi-dwarf rootstock as to their adaptability to biotic and abio­tic stressors as well as their economic productivity. The studied varieties appeared to be winter-hardy, frost- and heat-resistant, but medium drought-tolerant ones. They are characterized by weak and moderate susceptibility to powdery mildew, high resistance to fruit rot and very low amounts of brown spot, except for Gold Rush variety. Such 10 year old varieties as ‘Edera’, Florina’, ‘Amulet’ and ‘Perlyna Kyieva’ and 8 year old ‘Afrodita’, ‘Vitos’, ‘Orlovskoie Polesie’ and ‘Topaz’ formed the highest productivity during the years of study. Due to the pollen quality and high interfertility, ‘Revena’ and ‘Gold Rush’ varieties were identified as universal pollinators for winter scab-resistant apple varieties. Conclusions. Such ecologically resistant winter varieties as ‘Topaz’, ‘Freedom’, ‘Edera’ and autumnal ‘Remo’, ‘Afrodita’, ‘Vitos’, ‘Amulet’ were recognized as promising for new intensive non-irrigated plantations in the Forest-Steppe zone of Ukraine. They can be the basis of new gardens occupying 25–30% of the area where ecologically safe fruits for various target purposes will be grown supplying demands of the population and processing industry.

To analyse the modern classification and nomenclature of species of pome fruit crops which varieties are listed in the State Register of Plants Varieties Suitable for Dissemination in Ukraine, and improve terminological system of the Ukrainian names of both species and garden crops. Results. Fruit cultivars and most apple clonal rootstocks belong to Malus pumila, and ornamental cultivars belong to Malus gloriosa. The most common scientific name of the cultivated apple, especially among horticulturists, is Malus domestica, although according to the principle of priority the name Malus pumila should have the advantage. As far as Nomenclature Committee for Vascular Plants has rejected the proposal to conserve the name Malus domestica, Malus pumila is correct name for the cultivated apple. The use of synonymic name Malus domestica should be avoided in both scientific and scientific-popular papers for stability of nomenclature. Pear cultivars listed in the State Register of Plants Varieties Suitable for Dissemination in Ukraine are presented by Pyrus communis, and pear rootstocks – by Cydonia oblonga. Fruit cultivars of the latter belong to separate fruit crop named quince. An apple-quince hybrid was registered as universal clonal rootstock for pome fruit crops. The State Register of Plants Varieties Suitable for Dissemination in Ukraine also contains nonconventional fruit crops such as Chaenomeles and hawthorn that consist of some species and nothospecies. Conclusions. In scientific publications one should stop the use of synonymic name Malus domestica in favour of the correct name for cultivated apple Malus pumila. Apple, pears and Chaenomeles cultivars listed in the State Register of Plants Varieties Suitable for Dissemination in Ukraine have a complex multispecies origin whereas quince, hawthorn and pear roostock cultivars systematically are monospecies. A universal roootstock of pome fruit crops is Cydolus, or apple-quince, that resulted from interspecies hybridization between quince and apple. Refusal Refuse to use obsolete names of fruit plants species will promote harmonization of professional language.

Проанализировать современную классификацию и номенклатуру видов семечковых культур, сорта которых занесены в Государственный реестр сортов растений, пригодных к распространению в Украине, и усовершенствовать терминологическую систему украинских названий видов и садовых культур. Результаты. Плодовые сорта и большинство клоновых подвоев яблони относятся к Malus pumila, декоративные сорта – к Malus gloriosa. Наиболее часто употребляемым названием культурной яблони, особенно в садоводческих кругах, является Malus domestica, хотя за принципом приоритета преимущество имеет название Malus pumila. Так как Номенклатурный комитет по сосудистым растениям отклонил предложение консервации названия Malus domestica, Malus pumila остается правильным названием культурной яблони. Синонимическое название Malus domestica не следует использовать в научных и научно-популярных работах, что будет способствовать стабилизации номенклатуры. Сорта груши в Государственном реестре сортов растений Украины представлены Pyrus communis, подвои груши – Cydonia oblonga. Плодовые сорта последней относятся к отдельной культуре – айве. Айвово-яблуневый гибрид зарегистрирован как универсальный клоновый подвой семечковых культур. В Государственный реестр сортов растений Украины занесены также сорта нетрадиционных плодовых культур хеномелеса и боярышника, которые состоят из нескольких видов и нотовидов. Выводы. В научных публикациях следует перестать применять синонимическое название Malus domestica в пользу правильного названия культурной яблони Malus pumila. Сорта яблони, груши и хеномелеса, занесенные в Государственный реестр сортов растений, пригодных к распространению в Украине, имеют сложное многовидовое происхождение, тогда как сорта айвы, боярышника и подвоев груши в систематическом отношении являются моновидовыми. Универсальный подвой семечковых культур – цидол, или яблонеайва, является результатом в результате межродовой гибридизации айвы с яблоней. Отказ от употребления устаревших названий видов плодовых растений будет способствовать гармонизации профессионального языка. | Мета. Проаналізувати сучасну класифікацію й номенклатуру видів зерняткових культур, сорти яких занесено до Державного реєстру сортів рослин, придатних до поширення в Україні, та вдосконалити термінологічну систему українських назв видів і садових культур. Результати. Плодові сорти й більшість клонових підщеп яблуні належать до Maluspumila, декоративні сорти – до Malus gloriosa. Найуживанішою науковою назвою культурної яблуні, особливо в садівничих колах, є Malus domestica, хоч за принципом пріоритету перевагу має назва Maluspumila. Оскільки Номенклатурний комітет з судинних рослин відхилив пропозицію консервування назви Malus domestica, Maluspumila залишається правильною назвою культурної яблуні. Синонімічну назву Malus domestica не варто вживати в наукових і науково-популярних працях, що сприятиме стабілізації номенклатури. Сорти груші в Державному реєстрі сортів рослин України представлено Pyruscommunis, підщепи груші – Cydoniaoblonga. Плодові сорти останньої належать до окремої культури – айви. Айвово-яблуневий гібрид зареєстровано як універсальну клонову підщепу зерняткових культур. До Держаного реєстру сортів рослин України занесено також сорти нетрадиційних плодових культур хеномелесу й глоду, що складаються з декількох видів і нотовидів. Висновки. У наукових публікаціях варто припинити вживати синонімічну назву Malusdomestica на користь правильної назви культурної яблуні Maluspumila. Сорти яблуні, груші й хеномелесу, що занесені до Державного реєстру сортів рослин, придатних до поширення в Україні, мають складне багатовидове походження, в той час як сорти айви, глоду й підщеп груші в систематичному відношенні є моновидовими. Універсальна підщепа зерняткових культур – цидол, або яблунеайва, походить від міжродової гібридизації айви з яблунею. Вилучення з ужитку застарілих назв видів плодових рослин сприятиме гармонізації фахової мови.
