In the article the results of research of sowing properties - emergence rate and laboratory germinating capacity seeds summer rape are resulted depending on variants of fertilizers and terms of harvesting.

The authors presents the results of the collectional, primary and promotional investigation of the myrobalan plum large-fruited introduced and "tome cultivars under the conditions of the Ukraine's Southern Polissya and Northern Lisosteppe. On the background of the best standard cv <ubans’ka kometa a number of promise cultivars with both red and yellow fruits has been singled out to be introduced in the farm orchards of differ- ant forms of property. These cultivars are characterized with different Opening terms and purpose of fruits use.

The main principles of the forming of the scientifically based variety policy of Ukraine are described. A great role during the creating of varieties and hybrids with certain quantitative and qualitative characteristics belongs to the producers of the cereal and seed production, enterprises of the processing industry, firms, which supply their varieties to the world market.

Based on study of 42 collection entries, results of creating winter wheat initial material of high grain quality value and its relationship with agronomic traits are presented.

The influence of different conditions of conservation to sprout and germinating power of seed varieties of wheat under conditions of conservation are expounded in the article.

Ability of poly-unsaturated fatty Arachidonic Acid and Micosan bio-fun-gicide with 3% h.c.s.(alkali extract of alkilofraiic glucans mushroom - Fomes fomentarius) to oppress the pathogens' parasitism on the vegetable crops is experimentally proved. There is also studied biological efficacy of fungicides and their tank blends on the cucumber crop.

Regarding to the unstable climate and diversity of the Ukrainian soils, approved by the authors Conception of adaptive planting systems foundation owing to the implementation of local, complex, integrated, selective-agro-technical programs, theoretical background and construction princi-pals of which described in the study, are grounded, for different ecological zones of Ukraine.

It’s been shown the ways user impotent nucleotide plant of soybean, agriculture growing in the world last years. Revealed main point of formation nationality plant varieties resource of soybean.

Sugar beet hybrids are considered as a factor of intensification of the beet-sugar branch. At the modern stage of development of agriculture under condition of reduction of sugar beet sown area, shortage of material - technical resources which influence the formation of productivity of sugar beet as a crop of intensive type, hybrids must have a high genetically conditioned biological potential of productive ability, resistance to pests and diseases, abiotic stress factors, must have broad adaptive abilities. Analysis of the modern sugar beet hybrids included bately in the state Register of plant varieties of Ukraine is presented. Transfer of the branch to the intensive way of development is possible only under conditions of a complex approach to solving this problem.

In the article there are surveyed approaches to the use of biological - ecological potential of white head cabbage plants, given parameters of varieties adaptability and economically-valuable signs variability, depending on a temperature factor, water supply. The yield prognosis is worked out.
