Advantages of heterotic hybrids of the winter rape in the competitive and in the production testing proven. While certain advantages in the productivity of cultivar of the Czech selection of Odila above the domestic cultivar of Dangal got in the competitive testing in the production testing confirmed. It is established that the greatest productivity in the production testing was had hybrids Vsesvit F1t Zapalnyj Fb G-3 Fi and G-4 Fi, which are characterized the stable and yearly high productivity and combine the productivity with adaptability to the environmental conditions of area of Forest- steppe of Ukraine.

The history of creation and distribution of apple cultivar Renet Burhardta created by N .A. Gartvis is described.

The study results for many years (1972- 2006) of pear gene pool in the All- Russian Research Institute of Horticultural Breeding are given. The cultivars and selections have been singled out for wide dissemination and use in breeding.

It was studied the impact of mineral fertilizers on productivity and grain quality of wheat durum spring. Glassiness of grain, protein and gluten contain increase along with increase of doses of nitrogenous fertilizer. Maximum grain productivity was achieved by mineral fertilizers in combination on autumn fallow N60P60K60. after pea - N90P60K60

Methodical approaches to the cutting lettuce new varieties morphological characteristics grouping are found with regard to the botanical classification of the species. New morphological characteristics, used for new varieties of plants grouping and examination for distinctness are defined.

Results of four-years assessment of approximately 90 winter wheat varieties at post- registration research on the background of crops chemical protection and in its absence at Biloczerkivska DSDS (forest- steppe zone) and Borodianska DSDS (subforest zone) are represented in this article. Methods of their immunological assessment and determination of potential productivity have been developed too. Authors are recommending to conduct immunological assessment of varieties on their natural background of diseases development and assess potential productivity in conditions of plants chemical protection as this is the element of crop growing technology.

On the base of examinational institutions activity results summarizing by the Experts Council of State Variety Service, decision to recommend varieties for state registration of the proprietary right of intellectual property for dissemination, state registration of the proprietary rights of intellectual property, to approve the List of Perspective for Dissemination in Ukraine in 2008 Varieties, to decline state registration of the proprietary right of intellectual property, has been approved.

The author presents the results of studying of black currant 9 varieties resistance against pathogenic fungi.

The fruit of apple scab immune hybrids, obtained from the targeted crossings for suitability for juice production, were estimated. The most perspective hybrids were selected. They are not inferior to the world juice cultivars in the basic technological characters (juice output), and even surpass them in a number of these characters (the content of SDS and P-active catechols in juice).

The history of creation and distribution of apple cultivar Renet Burhardta created by N .A. Gartvis is described.
