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. To create new competitive spring wheat varieties. Methods. Field study, laboratory test. Results. Based on the competitive variety trial, bread spring wheat line ‘Lutescens 07-26’ has been selected due to high values of such traits as resistance to fungal diseases, grain quality(protein content accounted for 15.0%), 1000 kernel weight (44.6 g) productivity (3.92 t/ha) and lodging resistance (9 points). In 2011, it was submitted to the State variety testing as ‘Panianka’ variety. Durum spring wheat line ‘Leukurum 08-11’ was characterized by a number of positive traits: quite a high productivity (3.05 t/ha), short stem (79 cm), resistance to fungal diseases and lodging(9 points), and in 2011 it was submitted to the State variety testing as ‘Diana’ variety. According to the results of the State variety testing in 2012–2014, spring wheat varieties ‘Panianka’ and ‘Diana’ in 2015 were put on the State Register of plant varieties suitable for dissemination in Ukraine. Conclusions. For farms in Forest-Steppe and Polissia zones of Ukraine, bread and durum spring wheat varieties were bred by V. M.Remeslo Myronivka Institute of Wheat of NAAS of Ukraine that demonstrated rather high potential of productivity and adaptability to stress conditions. This goes to prove that cultivation of domestic spring wheat varieties will promote formation of high and quality grain yields.

There are allocated some forms of distant hybrids with weak degree of fungal diseases lesion (Taphrina deformans (Berk.) Tul., Sphaerotheca pannosa (Lev.) var. persicae Woron., Clasterosporium carpophilum Aderh., Monilia cinerea Bonord. и Monilia fructigena Fr.) that are of practical interest for breeding such cultivars of peach and nectarine that will resist these pathogens.

Purpose. To create and study genotypes of the secondary triticale of the hexaploid level for their effective use in further breeding and plant growing. Methods. Field study, laboratory analyses, intraspecific hybridization with subsequent individual selection. Results. New genotypes of the secondary triticale of the hexaploid level have been created and characterized for economic characters and agroecological traits and properties. Series of short-stem winter triticale was represented by ‘Pshenychne’, ‘Chaian’ to be adapted to the conditions of both intensive and organic farming. They are characterized by high drought resistance and winter hardiness, resistance to lodging, grain shedding, grain germination in the spike and spike fragility as well as by immunity to fungal diseases providing a high level of yield and technological quality of grain. The following new constant forms of triticale as ‘ПС_1-12’, ‘ПС_2-12’, ‘ПС_3-12’, that have an average height of the stem and belong to the Polissia-Forest-Steppe and Forest-Steppe ecotypes, demonstrated high productivity and adaptability in organic farming, particularly in case of the use of biologized elements of agrotechnology. Conclusions. For the creation a new parent material during breeding of hexaploid triticale, the method of intraspecific hybridization is desirable with the use of parent material to be contrasting for eco-geographical origin and adapted local forms, followed by individual selection of genotypes with the desired characteristics and properties in cleavable hybrid populations. New genotypes of the secondary triticale have been created and characterized for breeding, genetic and agroecological traits and properties. In breeding practice, it is advisable to use a whole new approach of agroecological and genetic certification of genotypes for the effective solution of a number of theoretical and practical tasks facing modern ecological and adaptive breeding. New parent material of the secondary winter triticale and scientific support for its cultivation is proposed for further breeding and plant growing.
