Purpose. To determine the possibility of the domestic viticulture transition to the ecological (adaptive) management system, based on the use of highly adaptive varieties. Methods. Procedures are conventional in viticulture. All stages of agrobiological research were carried out according to the M. A. Lazarevskiy technique. The resistance of genetic resources to fungal diseases was assessed using the 9-point scale on the natural infectious background with maximum damage. Organoleptic evaluation of wine and fresh grapes was performed using 8-point and a 10-point scales respectively. Results. The main agrobiological traits (resistance to diseases, productivity and yield quality) of 22 perspective grape varieties and forms were studied. The level of resistance to fungal diseases was determined as one of the main criteria of the variety suitability for ecological (adaptive) viticulture. During five years, the average resistance level of this group of table and wine varieties was not lower than the relative one (6.5–7 points), and in ‘Zagrei’ variety – up to 7,5 points. The level of quality characteristics of products of new grape varieties and forms was determined (wine evaluation, marketability and assessment of fresh table grapes). Samples with a combination of high wine and grape quality characteristics and high productivity were selected. To replenish the gene pool of grapes by adaptive varieties, such perspective hybrid combinations as ‘Opalovyi’ ´ ‘Burmunk, ‘Avgustin’ ´ ‘Oryhinal and ‘Ohoniok tairovskyi’ ´ ‘Kardyshakh’ were studied. The level of group resistance to fungal diseases was identified and the perspective genotypes were preliminarily selected. Conclusions. The level of display of a number of economic characters in the group of perspective table and wine grape varieties and forms was determined. Highly adaptive and highly productive varieties and forms suitable for the use in the adaptive viticulture were defined. Prospective hybrid combinations were considered, from which highly adaptive varieties will be selected as suitable for the ecological system of viticulture.

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. Reveal the peculiarities of the formation of national varietal resources of grapes, considering current state of the market, needs of consumers, problems and prospects of the viticulture industry in Ukraine. Results. The monitoring of the national varietal resources of the common grape vine in the chronology of the formation of a well-known varie­ties collection used both for food purposes and in the further breeding process. As of the beginning of 2019, 51 grape varieties of the common grape vine are included in the State Regis­ter of Plant Varieties suitable for dissemination in Ukraine. In recent years, there has been a tendency to a decrease in the number of new varieties, reduction in the total area of vineyards and young plantings. Technical varie­ties of the crop dominate in the Register of plant varieties of Ukraine; the assortment of the table grapes and universal groups needs to be expanded. The largest share among the common varieties in Ukraine is occupied by ones of domestic breeding. The results of monitoring of renewal dynamics of the common grape vine varieties in the State Register of Plant Varieties of Ukraine over the past five years indicate a negative trend: 2013 – 11 varieties, 2015 – two, 2018 – one variety. Therefore, the issues of the formation of national varietal resources of grapes are relevant and require a scientific approach to the breeding process, the state scientific and technical examination of the application for a variety of plants and their commercial circulation. New varieties of the common grape vine are included in the State Register of Plant Varieties of Ukraine based on the results of the state scientific and technical expertise on the plant variety; it provides for the establishment of criteria for distinctness, uniformity and stability using the morphological description of the identification signs of vegetative and generative organs of grapes and the determination of economically valuable indicators of new varieties. Conclusions. The total number of the common grape vine varieties in Ukraine for the period 2015–2018 decreased, due to the low level of applications for new varieties of both domestic and foreign breeding. The search for modern methods and directions of breeding, the use of new methods for crop varieties and clones identification remains a reserve for expanding the common grape vine assortment
