Purpose. To develop an algorithm of creation of new highly productive clonal varieties of Salicaceae family representatives with improved agronomic characters that can be used at energy plantations Methods. Field investigations, laboratory analysis, analytical approach, selection method. Results. Flow chart of selection process with representatives of Salicaceae family included the following stages: the Ist stage – creation of primary families (F0); the IInd stage – creation of the second families, or branches; the 222rd stage – interfamily (individually-familial) selection; IVth stage – familial-group selection; the Vth stage – clonal selection (selection of ramets). Conclusions. Breeding process with the use of complex of advanced methods of selection (individual, familial, group and clonal ones) allows to get model populations with high-frequency of valuable alleles and genotypes and with the high level of genetic variety. Due to a negative multi-stage individual intrafamilial and interfamily selection, cleaning of artificial populations from undesirable forms takes place without the substantial decrease of genetic variety level.

Purpose. Developing methodical aspects of assessing grape breeding material in hybrid combinations for a number of indicators of adaptability and productivity. Methods. Breeding, hybridological, statistical ones. Results. Main requirements were determined for a new generation of table and technical grapes that was based on the set breeding task and patent searches, literary sources and Internet resources. 12 main indicators of adaptability, productivity and quality of products were analyzed, a high level of their display is required for pre-selection of grape seedlings for further study. Gradation from the lowest level of display of the above economic characters of grapes to the medium and high ones was developed. For their definition points-based system is used – the lowest level of display corresponds to one and three points, average – five, and high – seven and nine. As a result, studied plants can score 12 to 108 points. Variation in the plant evaluation over the years should not exceed 10 points. A seedling cannot be selected by the maximum level of displaying only one parameter, in the same manner as it shall be rejected with a minimum level of display of any of the said indicators. Seedlings that display a stable middle level of traits can be placed to the breeding nursery to study the level of display of the essential parameters and properties of the grafted culture. Conclusions. Criteria and basic parameters of genotypic values in hybrid combinations were determined. Plants that have been estimated in 60 points or higher may be considered as promising ones, that is those which require further studying. Valuable genotypes correspond to the level of 80–100, very valuable – of 101–108 points.

Purpose. To develop and improve adaptive technologies of winter wheat cultivation which provide high productivity and quality of grain. Methods. Field and laboratory stu­dies, mathematical and statistical analysis. Results. During 2011–2015, the impact of cultivation technologies on the formation of grain quality and yield of winter wheat varie­ty ‘Stolychna’ (with pea as predecessor) was studied. When using alternative technologies with only predecessor by-products application, the yield of winter wheat with integ­rated crop protection system was 4,56 t/ha, with minimal protection – 4.25 t/ha with grain quality of the 5th class of B group. Resource saving cultivation technologies with limi­ted application of fertilizers (Р45К45N30(II)+30(IV)) provided productivity at the level of 4,87–5,50 t/ha with grain qua­lity of the 2nd–3rd class of A group. Grain yield of 6.01 t/ha with indicators of the 2nd–3rd class of quality was obtained with the use of intensive cultivation technology with application of mineral fertilizers (Р90К90N30(II)+60(IV)+30(VIII)) on the background of applying predecessor’s by-products and integra­ted crop protection. The highest yield of grain (6.22 t/ha) with indicators of the 2nd class of A group quality on average for the research period was provided by energy-intensive technology, that requires the application of mineral fertilize­rs (P135K135N60(II)+75(IV)+45(VIII)) and incorporation of predecessor’s by-products in the soil, and integrated plant protection. Conclusion. It was found that in the northern part of the Right-Bank Forest-Steppe zone of Ukraine, the highest productivity of winter wheat was obtained in dark grey podzolic soils when using the energy-intensive technology with application of P135K135N60(II)+75(IV)+45(VIII) on the background of predecessor’s by-products and integrated crop protection. This technology ensured the grain yield of 6.22 t/ha of the 2nd class of A group quality.
