Such varieties of winter wheat as Ovidium, Kokhana, Blago, Maria, Andromeda possess high adaptive potential, there are possible to use on irrigated and unirrigated lands. New genotypes are able to guarantee yield on level accordingly 9,0-9,5 and 5,5-6,0 t/ha. They are form the grain of strong and valuable wh eats.

By means of directed hybridization and selection, a new donor of Winter Rye with combination of ultra short stem and absence of wax coating has been synthesized. Markings was offered for the first time for dominant genes of ultra short stem characteristic – HI-3HI-3, and for recessive genes of absence of wax coating characteristic – wcwc. Determination is made of genetic variability, coefficients of inheritance, phenotype and genotype correlation coefficients, on the basis of which a selection strategy by ten quantitative characteristics is proposed. Polypheny and cohesion effects were established. Under certain conception, strategy and tactic of improvement by breeding of Winter Rye characteristics, determination of genetic and statistic parameters between traits of parents and the offspring is required.

The article highlights Kharkiv Breeding Facility, later referred to as Plant Production Institute named after V. Iuryev in 20s-80s concerning breeding the Winter Wheat in Ukraine and impact of the varieties obtained on th productivity increase. It is established that thanks to the efforts of V. Iuryev, V. Didus, M. Ielnikov, A. Shulyndina and others for the period of 1920s-1980s a number of economically valuable varieties have been created – Multrum 120, Iuryivka, Lutetsnes 266, Zenitka, Salut, Kharkivska 1, Kharkivska 32, Khar-kivska 81 and others. Thanks to efforts in breeding the yield index was growing gradually and reached the average level of 4,3 tons per hectare. In particular, in 1921–1930 – 2,33 ton/hectare, 1931–1940 – 2,42, 1941– 1950 – 3,01, 1951–1960 – 26,5, 1961 – 1970 – 4,3, 1971–1980 – 5,05, 1981–1990 – 4,47 t/hectare. In recompense for significant achievements in agricultural crops varieties breeding a breeding center was founded at the facilities of Plant Production Institute named after V Iuryev was founded in 1976.

The article provides summary of the research on inheritance, stability and variability of the Wheat morphologic characteristics, genotypes identification and examination of distinctness, uniformity and stability. Proposal is made to use alter characteristics for identification of biotypes and new candidate varieties for reference collections.

Proposed system approach for freezing tolerance estimate of breeding material of winter wheat allows to differentiate the samples by physiological properties of resistance to low temperatures and based on to carry out selecting parents for hybridization in changeable environments of global warming.

The composition developed for conveyer production of commercial yield of Cutting Lettuce in the Ukrainian Woodland Conditions. Terms of the open ground conveyer commercial yield delivery to the customer depending on agrotechnologic growth actions are scientifically founded.

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.

Sowing dates and response to them of newly registered and perspective varieties of winter wheat were studied. Reasons provided for changing sowing dates to the later.

Water-soluble carbohydrates, cytokinins, ABA, salicylic acid and microelements content's dynamics in wintering underground organs of P.alba and G.nivalis were studied. Correlation between substance's level and air temperature, ground freezing depth, snow layer thickness fluctuations was determined. The role of phytohormons and free sugars in adaptive potential realization are discussed.
