Purpose. To use GGE biplot analysis for assessing varia­bility of spring barley varieties yield and identify the most valuable genotypes. Methods. Field, mathematical-and-statistical ones. Results. GGE biplot in the form of polygon showed that environments Е1, Е3 and Е4 form the first «megaenvironment» in which Donetskyi 15 variety «wins», environment E2 – the second «megaenvironment» in which Vzirets variety «wins». The varieties Stepovyk and Donetskyi  14 had the highest average yield while the varieties Modern, Vektor, and Kozvan were marked by their high stability. The Stepovyk variety appeared to be an «ideal» genotype in terms of combining yield capacity and its stability as compared to other genotypes. The Donetskyi 14, Kosar and Alegro varieties are also valuable regarding yield capa­city and stability. Conclusions. According to the results of studies, GGE biplot is recommended to use for analysis of environmental test data.

Abstract The objective of this study was to document the infection by cestodes Crepidobothrium sp. in Bothrops atrox, which are from the Tapajós National Forest, located in the western part of Pará state, Brazil. Thirty-six specimens of B. atrox were examined, of which 13 individuals (36%) were infected by Crepidobothrium sp. and a total of 147 parasites were collected from these hosts. The mean abundance of these endoparasites was 4.1 and the mean infection intensity was 11.3. In relation to parasitic infection sites, 88.4% of these cestodes were found in the small intestine, 9.52% in the large intestine and 2% in the stomach of the hosts. This was the first report of Crepidobothrium sp. in B. atrox in the Brazilian Amazon.

Purpose. To study interactions among the representatives of the genus Salix L. through the cluster analysis, form groups of closely related species and hybrid forms basing on differences of morphological parameters of leaves. Methods. Field, cluster analysis and tree graphics. Results. Willow species were grouped according to absolute parameters of leaf, and three groups of clusters were identified. The degree of affinity between species were assessed using values of an Euclidean distance. Distinctive features of leaf parameters were defined: length of a leaf blade (Ll), distance (cm) between the leaf tip and its maximum width (SDmxT) and the distance between the leaf tip (cm) and the line of its width that corresponds to the length of petiole (SLpT). Conclusions. Using the willow species collection as an example, diagnostically valuable quantitative parameters of leaves were revealed, the use of which allows to identify willow species and hybrid forms through PC applications.

Purpose. To study the effect of growth regulators EpinTM and Emistym C on yield and quality of strawberry berries of five varieties (Fragaria ananassa (Weston) Duсhesne ex Rozier) with various ripening time. Methods. Field, laboratory, analytical and statistical ones. Results. It was found that there were no impact of growth regulators EpinTM and Emistym C on the speed of phenological phases of strawberry plants development. It was experimentally determined the impact of mentioned substances on the yield of most studied varieties. Laboratory analysis has confirmed the changes in biochemical composition of strawberries. Conclusions. The use of growth regulators EpinTM end Emistym C had a positive effect on fruit yield and quality of studied strawberry varieties. Spraying with these substances increased yields by 14–51% as compared with the control. Content of sugars, dry matter and vitamin C in berries of most of varieties was increasing. At the same time the level of acidity in case of spraying with growth regulators was significantly reducing.

Purpose. Determination of optimum dozes of foliar fee­ding for each cultivar that will provide the highest output of standard rootstocks. Methods. Field, analytical and statistical ones. Results. The author presents the results of study of the hazelnut plant foliar feeding in the mother plantation for vegetative propagation with applying different carba­mide concentration combined with 0.1% potassium sulfate (1.50.4 m) in case of horizontal method of growing. Biometric indices of hazelnut layers were analyzed; the influence of each factor on their height and diameter was determined. The rootstocks output per 1 linear meter for each cultivar as well as optimum foliar feeding doze was defined (0.5% carbamide with 0.1% potassium sulfate). Conclusions. The highest output of standard rootstocks in the mother plantation for horizontal vegetative propagation was achieved when applying the foliar feeding with 0.5% carbamide combined with 0.1% potassium sulfate, particularly (thousand rootstocks per 1 ha) for the cultivars: ‘Sviatkovyi’ – 66.7, ‘Dolynskyi’ – 62.1 and ‘Darunok Yunnatam’ – 50.7. For ‘Koronchatyi’ cultivar, the use of 3% carbamide was the most efficient.

Purpose. Reviewing the EU legislation on plant varie­ties protection including documents of the International Union for the Protection of New Varieties of Plants (UPOV) that related to the national laws of its member states. Results. Based on the sources processed, the authors give a brief analysis of the basic EU Council Regulation № 2100/94 of 27 July 1994 on Community plant variety rights and regulations of the European Commission adopted to implement it. Basic copyright concepts, features of plant varieties protection in the EU, including those under the UPOV Convention, are also considered. Conclusions. For Ukraine, obtaining full membership in the EU, on the one hand, requires harmonization of its laws with the re­levant EU legislation, on the other – improvement of the present system of plant varieties protection taking into account national interests of Ukraine.
