As a result of the lead long-term selection works wint involving a World' s collection and intertype and intertype hybridization with purposeful selection on economic-biological attributes highly productive • grades of a winter wheat, with stability to various kinds of illnesses and high technological qualities of grain have been allocated. The adapted grades of a winter wheat for a various environment of various zones of the countries of the Central Asia that allows to realize potential opportunities of grades in different environments of cultivation and by that to prevent losses of a crop from biotic and abiotic stresses that allows to stabilize productivity and adaptability of culture in a zon winter husbandry are created. The long-term field experiences lead by us and laboratory analyses on a level of productivity, qualities of grain and stability to stresses allows to conclude, that alongside with a genotype, stabilityenvironmental conditions render strong and significant influence on all complex of selection attributes.

There provided ways of using valuable protein crop, soybean, as well as its production worldwide growth rates during recent years, possibility and necessity of attaching to the crop a strategic importance in our State and the tasks and outlooks of soybeanrecourses generation. A complete description of new soybean varieties listed in the Register of Varieties Suitable for Dissemination in Ukraine has also been provided.

Asa result of supervisions, estimation, description, and analysis of 13 morphological, biological, biometrycal and economic valuable signs 26 varietis of pea vegetable are set sizes of phenotypical coefficients of correlation between them.

The chemical composition and the links between different groups of substances (content of dry substances, monosaccharides, saccharose, sum of sugars, titratable acids, proanthocyanidins, anthocyanidins, water soluble pectine, protopectin, sum of pectines and sugar-acid index) have been studied in hybrids fruits of Persica vulgaris Mill, subsp. erytrocarpa Zajats and Persica vulgaris Mill, subsp. atropurpurea (Schneid.) Zajats. The obtained data were compared with the characteristics typical for fruits of P. vulgaris Mill, subsp. nectarina (Ait.) Shof. and P. vulgaris Mill. Brief information about the biology of obtained distant hybrids forms have been given. The content of anthocyanine pigments (Cy-3-Glu, Cy-3- Ara, Cy-3-(6-Kum)- Glu) in fruits and leaves of different taxons for genus Persica Mill, has been analysed.

Investigational development of modern treater seed of agricultural cultures status. The analysis of efficiency of work control the system modem treater seed is conducted. The ground of creation of cont rol the system by the concerted serve working liquid (liquid poison) and seed is conducted in the working area of treate.

In given article the historical way of development of selection of sugar beet at the Ivanivska research-selection station is opened. For 100 years of selection work at station by scientific employees are created and introduced into manufacture over 20 grades of sugar beet.

Tere are discussed results of joint Bukovino-moldavian corn breeding programmer, as a result which are created two registered hybrids, one perspective, and new material for the further work.

Outcomes of reciprocal crossings new Rye donor of super-short stem with electroidness Hl-3Hl-3elel and tall Rye Variety Viatka 2 are provided. The firs generation hybrids appeared to have a short stem with regular leaf blade. In the second generation the female parent effect of short stem domination was established, as well as complete domination of tall bushiness, long-spiked plants, increased number or grains in the ear. Weight of 100 grains in the ear made 22,79 і 29, 41% of the heterosis relative to the best parent. According to the results of the research of genetic and statistical parameters of F2 breeding characteristics plants with electoid leaf blade shape were selected.
