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.

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.

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 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 pomological description of studied samples has been given; the chemical composition and relation between biochemical characteristics in fruits of Prunus cerasifera subsp. macrocarpa (Erem. et Garcov.) var. pissardi Bailey has been studied. The obtained data are compared with characteristics, typical for fruits of varieties Prunus cerasifera Ehrh. and forms of Persica vulgaris subsp. atropurpureae (Schneid.) Zajats.

The article considers national varietal sources of sugar beets, namely the progress of their generation, as well as general characteristics of productivity. Main trends in breeding reflecting the needs of society are highlighted. Importance of official qualifying examination for generating high-quality varietal diversity aimed at meeting the needs of national beetroot industry is emphasized.

The article reflects the progress of genetic decrease of Rye F 3k- 10029/ Saratovske (Саратовське) 4 height by means of the shortest stem plants selection during the period from 1974 to 2010. 37 years selection of the shortest- stern genotypes decreased the plants height from 119.33 cm to 22.57cm. Targeted selection into minus direction decreased the plants height in 5,29 times on the background of the dominant HI expression. In average, the height of plants in the course of 27 breeding cycles were decreasing by 2.69 cm, but that was not going gradually. A new donor Gnom 3 had been created for ultra short-stem trait of the Winter Rye, with the marking of alleles HI-3HI-3. Relative influence on the minus selection efficiency has been established by height of plants for the selection differential (38%) and coefficient of inheritance in narrow sense (14,56%). Realized efficiency of selection in decrease of winter rye height in 72,08% of cases corresponded to predicted hit ration of the breeding. Analyzes of genetic and statistical parameters and correlation clusters of 11 utilitarian average characteristics of ultra short- stem rye Gnom 3 for the period of 1974 to 2010 has been performed.

Purpose. Determining prospects of introducing Callistephus chinensis cultivars of foreign breeding for further cultivation under conditions of the Central Forest-Steppe zone of Ukraine. Methods. Field, laboratory, analytical and statistical ones. Results. Ten C. сhinensis cultivars of theGerman breeding were tested under conditions of the Central Forest-Steppe zone of Ukraine. Biomorphological traits of the varieties of five sort types were identified, and their comparative analysis was conducted. Seasonal dynamics of growth and development of cultivars in the growing area was studied. Conclusions. Cultivars with short and mean duration phases of development can be grown under conditions of the Central Forest-Steppe zone of Ukraine by direct sowing that does not affect their seed productivity and sowing quality of seeds. Seeds of late cultivars can reach complete maturity only in case of seedling use. C. chinensis cultivars of the German breeding have successfully passed the initial test for suitability to introduction into the studied area.
