Purpose. To enrich and improve the range of table grape varieties of Ukraine. Methods. Breeding, hybridological, mathematic, visual ones. Results. Modern Ukrainian gene pool of table grape varieties has been created on the base of the best introduced and homegrown cultivars and selections. New genotypes that are creating at the National Scientific Centre “Institute of Viticulture and Wine-Making named after V. Ye. Tairov” under the breeding program “Resistense plus Quality” are the basis of current and future regional assortments for the south and central areas of the steppe zone of Ukraine. The complexity of the origine explains the genetically determined high-level manifestation of commercially valuable characters. New varieties and selections are ecologically safe for humans and the environment, as the level of their resistance to the group of fungal main diseases is not less than 6.5 points according to the 9-point scale, therefore they do not require a large pesticide load. New promising table varieties demonstrate a stable yield and high marketability of grapes – 5–10 kg per plant with the marketability nearly 80–87% during the last five years. In addition, dense flesh of grapes is a guarantee of high transportability. The variety of table genotypes taste, shape and berries ripening from very early to very late embodied in the innovative and highly profitable development “Conveyor of table grapes”. Depending on the ecological and geographical conditions, the conveyor can include a diffe­rent quantity of varieties, but to in order increase the efficiency and profitability it is necessary to have a few groups (from 2 to 4 varietes) of different ripening. The approximate ratio (%) of varieties of different ripening time is recommended: very early – 22%, early – 22%, average – 17%, mid-late – 17%, and late – 22%. Conclusions. The variation of shape, flavour and color of new promising genotypes of table grapes makes them very popular on the market and may satisfy the most demanding consumer. The stability of the adaptive and technological traits makes the new table varieties very attractive for the producers of grape products.

Purpose. Study of winter wheat varieties that were bred at the Institute of Irrigated Farming NAAS through ecological testing in Turkey. Test procedures both in Ukraine and Turkey meet the requirements of the International Union for the Protection of New Varieties of Plants (UPOV). Methods. Field, laboratory ones: structural analysis, quality analysis, statistical analysis. Results. The Exporter Unions Seed and Research Company (ITAS) during 2011–2013 tested winter wheat varie­ties bred at the Institute of Irrigates Farming (IIF) NAAS at four areas of the Central Plateau of Turkey comparing them with local varieties registered in this country. According to the results of these tests the Exporter Unions Seed and Research Company identified Kohana variety as candidate for the state registration in Turkey. Conclusions. The realisation of the innovative product in Ukraine and entitlement to use intellectual property due to licensing agreements is expected. The Institute of Irrigated Farming NAAS continues to create new varieties of winter wheat which can be transferred to other countries for testing for the purpose of introduction and further expansion.

The research of 122 breeding lines of winter wheat to adaptability have been carried out for three years at three points. Samples for ecological variety testing were determined which have both high and average stability and plasticity, high average yield and are promising for qualified examination. The environments are analyzed for differentiating ability. Environments were selected which allow to identify genotypes for yield potential and adaptive ability. It is established that the parameters of adaptive ability and stability of winter wheat samples obtained during cultivation both in various geographical locations and at one point during some years were closely correlated. This confirms the hypothesis that the genotype estimate for adaptive ability in one location is reliable. The connection level was average only for the variance of genotype–environment interaction. However, this parameter is not principal therefore this connection level does not restrict significantly the use of the method in general.

Цель. Установить основные критерии адаптивности и определить адаптивную способность различных сортов картофеля, проходивших сортоиспытание в условиях Полесья и Лесостепи Украины для использования в семеноводстве. Методы. Продуктивный потенциал сортов картофеля для определения общей видовой адаптивности анализировали по показателю урожайности. Для этого использовали коэффициент адаптивности сортов (КА) по их урожайности в год выращивания к среднесор­товой урожайности года. Результаты. За годы исследований (2014–2016) при одинаковых условиях выращивания сорта по-разному реагировали на условия среды относительно года испытания. Общий коэффициент адаптивности 1,0 и выше свидетельствует о повышенной адаптивности сорта в почвенно-климатических условиях зоны выращивания к изменению погодных условий в течение вегетационного периода. В частности, на Полесье это сорта ‘Эсми’ (КА 1,12), ‘Катания’ (КА 1,06), ‘Констанс’ (КА 1,03), в Лесостепи – ‘Эсми’ (КА 1,16), ‘Катания’ (КА 1,12), ‘Констанс’ (КА 1,00). Специфическая адаптивная способность сортов отмечается при высокой среднесор­товой урожайности в годы, благоприятные по погодным условиям для культуры картофеля. Прирост урожая таких сортов на Полесье составлял 0,4–1,9 т/га, в Лесостепи – 0,7–2,8 т/га. К таким сортам в зоне Полесья относятся ‘Есми’, ‘Катания’, ‘Явир’, ‘Констанс’, в Лесостепи – ‘Есми’, ‘Катания’ и ‘Констанс’. Выводы. Использование коэффициента адаптивности (КА) позволяет определить продуктивную способность сорта в конкретных почвенно-климатических условиях. Выращивание сортов с повышенной адаптивностью является весомым фактором увеличения объемов производства высокопродуктивных сортов картофеля, прежде всего семенного материала высоких категорий для сортоcмены и сортообновления. По результатам исследований к таким сортам картофеля в условиях Полесья и Лесостепи относятся ‘Эсми’, ‘Катания’ и ‘Констанс’. | Purpose. To define the main criteria for adaptability and determine the adaptive capacity of different varieties of potatoes tested in Polissia and Forest-Steppe of Ukraine for use in seed production. Methods. The productive potential of potato varieties to determine overall species adaptability was analyzed in terms of yield. For this purpose, the coefficient of adaptability of varieties (CA) was used determined by their yield in the year of cultivation in ratio to the ave­rage yield of the year. Results. Over the years of research (2014–2016), under similar conditions of cultivation, the varieties responded in different ways to conditions of the environment in relation to the year of testing. The overall CA of 1.0 and higher indicates increased adaptability of the variety in the soil and climatic conditions of the growing area to changes in weather conditions during the growing season. In particular, in Polissia these are ‘Esmi’ (CA 1.12), ‘Catania’ (CA 1.06), ‘Constans’ (CA 1.03); in the Forest-Steppe – ‘Esmi’ (CA 1.16), ‘Catania’ (CA 1.12), ‘Constans’ (CA 1.00). Specific adaptive ability of varieties is manifested in high average variety yields in years favorable by weather conditions for potato cultivating. The increase in the yield of such varieties in Polissia was 0.4–1.9 t/ha, in the Forest-Steppe – 0.7–2.8 t/ha. ‘Esmi’, ‘Catania’, ‘Yavir’, ‘Constans’ belong to such varieties in Polissia, ‘Esmi’, ‘Catania’, and ‘Constans’ – in the Forest-Steppe. Conclusions. The use the coefficient of adaptability allows determining the productive capacity of a variety in specific soil and climatic conditions. The cultivation of potato varieties with increased adap­tability is a significant factor in increasing the production of high-yielding potato varieties, primarily seed material of high categories for varieties rotation and replacement. In particular, according to research results, such varieties of potatoes in Polissia and Forest-Steppe conditions are ‘Esmi’, ‘Catania’ and ‘Constans’. | Мета. Установити основні критерії адаптивності та визначити адаптивну здатність різних сортів картоплі, що проходили сортовипробування в умовах Полісся та Лісостепу України, для використання в насінництві. Методи. Продуктивний потенціал сортів картоплі для визначення загальної видової адаптивності аналізували за показником урожайності. Для цього використовували коефіцієнт адаптивності сортів (КА) за їх урожайністю в рік вирощування до середньосортової врожайності року. Результати. Упродовж років досліджень (2014–2016) за однакових умов вирощування сорти по-різному реагували на умови природного середовища відносно року випробування. Загальний коефіцієнт адаптивності 1,0 і вище свідчить про підвищену адаптивність сорту в ґрунтово-кліматичних умовах зони вирощування до зміни погодних умов упродовж вегетаційного періоду. Зокрема, на Поліссі це сорти ‘Есмі’ (КА 1,12), ‘Катанія’ (КА 1,06), ‘Констанс’ (КА 1,03); у Лісостепу – ‘Есмі’ (КА 1,16), ‘Катанія’ (КА 1,12), ‘Констанс’ (КА 1,00). Специфічна адаптивна здатність сортів виявляється за високої середньосортової врожайності в роки, сприятливі за погодними умовами для культури картоплі. Приріст урожаю таких сортів на Поліссі становив 0,4–1,9 т/га, у Лісостепу – 0,7–2,8 т/га. До таких сортів у зоні Полісся належать ‘Есмі’, ‘Катанія’, ‘Явір’, ‘Констанс’, у Лісостепу – ‘Есмі’, ‘Катанія’ і ‘Констанс’. Висновки. Використання коефіцієнта адаптивності дає змогу визначити продуктивну спроможність сорту в конкретних ґрунтово-кліматичних умовах. Вирощування сортів з підвищеною адаптивністю є вагомим чинником збільшення обсягів виробництва високопродуктивних сортів картоплі, передусім насіннєвого матеріалу високих категорій для сортозаміни і сортооновлення. За результатами досліджень до таких сортів картоплі в умовах Полісся й Лісостепу належать ‘Есмі’, ‘Катанія’ та ‘Констанс’.

Purpose. To establish adaptive capacity and reproduction time of the registered potato varieties elite bred at the Potato Research Institute of NAAS of Ukraine in various edaphic and climatic zones of Ukraine. Methods. Field and laboratory tests, statistical evaluation. Results. Potato varieties were tested in the Forest-Seppe, Polissia and Steppe zones of Ukraine. Over the years of testing (2012–2014), the highest yield of potatoes in the south-western part of the Forest-Steppe zone was produced by the early varieties: ‘Kimmeria’ – 46.9 t/ha, ‘Vedruska’ – 38.6 t/ha; middle-early varieties: ‘Partner’ – 33.2 t/ha, ‘Fantazia – 27.7 t/ha; mid-season varie­ties: ‘Okolytsia’ – 35.4 t/ha, ‘Mandrivnytsia’ – 25.1 t/ha. In the Central Polissia, ‘Kimmeria’ (31 t/ha) was the most productive early variety, the yield at the level of 27.6–29.2 t/ha was formed by such varieties as ‘Skarbnytsia’, ‘Serpanok’, ‘Radynka’, ‘Tyras’. Among the middle-early varieties, the yield of 33.1 t/ha was obtained from the variety ‘Partner’. In the conditions of Steppe zone, such early potato varieties as ‘Vymir’, ‘Glazurna’, ‘Strumok’, ‘Kimmeria’, ‘Svitoch’ and the middle-early variety ‘Ariya’ had the highest productivity in case of gro­wing as bivoltine crop under irrigated conditions. It was found that in the Forest-Steppe and Polissia zones such varieties as ‘Kimmeria’, ‘Vedruska, ‘Serpanok’, ‘Skarbnytsia, ‘Tyras’, ‘Radynka’, ‘Partner’, ‘Slovianka’, ‘Vernisazh’, ‘Mandrivnytsia’, ‘Poliske dzherelo’ and ‘Chervona ruta’ were characterized by high resistance to degeneration (viral diseases and loss of productivity of potato elite in the process of reproduction). According to the results of evaluation of the impact of elite potato reproduction time on affection by viral diseases, optimal time for elite renovation for investigated varieties was determined. Conclusions. In the process of testing in various edaphic and climatic zones of Ukraine, stable yield with a high seed tubers number, regardless of weather conditions during the growing season in the Forest-Steppe and Polissia zones, was formed by some early potato varieties (‘Kimmeria’, ‘Vedruska’, ‘Radynka) and middle-early one (‘Partner’). Among mid-season varieties ‘Vernisazh’, ‘Okolytsia’, ‘Mandrivnytsia’ were identified for high productivity, and among middle-late – ‘Poliske dzherelo’ and ‘Chervona ruta’. The most common viral diseases of potatoes were rugose mosaic and mosaic leaf curling. High efficiency of the use of bivoltine crop method for potato growing to obtain seed material in the Southern Steppe zone of Ukraine has been proved.
