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.

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.

Results of amino acids composition studying in savoya cabbage assortment are served. The best samples namely Vertyu 1340 (Rusiia) and hybrid Saha F1 (Netherlands) were selected.

The sorts different by economic-biologic character of unshed seed, breeded in Ukraine and abroad obtained wide spreading in production. Expediency using lugansky or samarsky type of determinant stability to healthy growth. Breeding sorts with tendril type of leaf give the positive results in increase stability of the plants to damping-off. The sorts combining named recessive character with another aconomic-value traits of grain pea made and suggested to production.

Revealed main point of formation the matrix differences of lettuce seeds characteristics (Lactuca sativa L.), its correlation with other categories of heterogeneity. It’s been shown the ways of decreasing of the matrix differences of lettuce seeds characteristics with the aim to increase sowing quality of seeds.

It has been supposed to carry out bred-making valuation of wheat under native condition of protein substances and contents of the dough improvers (КВrO3, С6Н8О6) being practiced. It will allow both at present and in the future to carry out comparative valuation by this index between varieties of various breeding progenies.

Questions of winter wheat cultivation in rice crop rotations, which further to make the most efficient use of soil, increase of fertility and receive an additional yield per unit of crop area are studied in the article. The results of ecological variety test of winter wheat in rice check conditions have represented. The varieties with the best adaptive properties, yield and high qualitative indices of grain are park out. The conclusions about expediency of burther study improvements guestions of winter wheat ecological variety test are made with the purpose of selection varieties the most adapted to specific rice checks contions.

The genealogy of the separate sorts of mild winter of International Breeding Research Laboratory V. N. Remeslo Mironovka Institute of Wheat were analyzed. And sources of forming the sings, providing their high adaptability, were also found . it is shown that the main role in sort productivity, their stabilityto sickness and to unfavourable factors of environment played a starting material of west-european ecotype.

In clause the role and development of the Ivanovo skilled - selection station, as research establishment is determined. A creative way founder of selection work on sugar beet and grain cereals of Boris Nikolayevich Lebedinskiy, outstanding scientific, large connoisseur of a technique of research work, creator of an agricultural science also is directly opened.
