The article provides new approach to complex assessment of phenolic compounds composition in table grape involving high-performance liquid chromatography. It also offers results of optimizing methods for analyzing and sample preparing of a grape berry in order to scrutinize the composition of phenol compounds.

In the article was analyzed the system of organization variety examination in one of the most economic development state-member of Union for plant varieties of Plants - Federal Republic of Germany. The structure of administrative authority of plant variety protection - Bundessortenamt and variety testing station enlightened, suggested specific economic indices that could be an example for formation and development national breeding and seed production.

Methodology for detecting correspondence of soft wheat to the criteria of distinctness, uniformity and stability based on researching peculiarities of morphological characteristics expression, has been scrutinized. It is established that, in the complex of many of those characteristics characterizing variety phenotype, for its identification only those characteristics are used that are exposed to lesser degree to the influence of environmental conditions.

The article offers results of genetic value assessment for pollinators resulted from population of high-productive and sugary specialization of Uladivska breeding, to be used for their recurrent improvement and development of hybridization components valuable for combining in creation of synthetics and MS hybrids of sugar beet containing reduced amount of nitrogen α-amin ions.

The article offers short characteristic of Fj hybrid combinations and reveals type of inheritance by the folwiing characteristics: plant height, height of lower bean insertion, quantity of seeds per plant, quantity of seeds per plant, beans per plant, nodes and branches per plant, as well as determines proportion of dominations displaying high heterosis effect. Two superior hybrid populations, namely Amethyst/Miao-ian-Dou and Amethyst/Krasa Podillia, have been selected and are being used to scan for transgressive forms.

The article shows the dependence of economic efficiency of production of winter wheat cultivation technology and the degree of intensity of cultivation of the variety. Comprehensive considered one of the main characteristics of the variety, namely the degree of intensity of cultivation of the variety.

The results of investigation of pigmental complex and anatomical structure of red currant leaves in connection with the drought resistance are given. The genotypes of red currant: «Gazel», «Belka», «Jonker van Tets», «Viksne», «Selyanochka», «Niva», «Gollandskaya krasnaya», «1432-29-98» and «1426-21-80» have more xeromorphic structure of leaves, providing of ecological tolerance to drought and high temperature. Varieties «Roza», «Dana» have a low adaptation to drought resistance.

The high content of phenolic compounds (quercetin-3-O-glycoside, izoramnetine-3-O-glycoside, 4'-metoxykempferol-3-O-glycoside, 4'-metoxyqvercetine-3-0-glycoside, apigenine and luteoline) in flowers of Prunus cerasifera Ehrh. in comparison with Prunus armeniaca L. has been shown. That can be the reason weak susceptibility of generative organs of cherry-plum to Sclerotinia (Monilinia) laxa (Aderh et Ruhl.) Honey.

Assessment is made for heat-resistance of 10 promising domestic and foreign apple varieties, as well as for their drought- resistance (leaf tissue water content, water holding capacity and turgorescence); also, impact of weather conditions on implementation of its drought and heat resistance by the research subject is determined. The article highlights the best in Ukraine’s Forest-Steppe environment by the above economical and biological properties apple varieties.
