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.

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.

Scope of protection of plant variety rights granted to variety owner as provided for by Ukrainian legislation is established. Thus, basis is created to enable comparative analyzes of the national system of plant variety protection with analogous sys-terns existing in other countries, in particular, the protection available with utility patent.
