There is the method represented in the article for frost resistance determination for Winter Wheat (soft and hard) varieties by experts’ assessment of varieties submitted for Official Variety Studying. Prescribed temperature limits for artificial freezing of the plants, example varieties for frost-resistance groups, are indicated.

The yields result of different varieties winter wheat in four State variety testing station of Cherkassy region is shown. Most ecological plastic varieties are determined.

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

Possibility of heterosis effect approbation by using synthetic varieties of winter rye was discussed. Heterosis level of first five generation of rye synthetics did not decrease. Considerable yield decrease of winter rye grain took place in later generations. Concept of synthetic varieties of winter wheat creation in Ukraine is prospective, though it requires scientific, economical and legal improvement.

In the Mironivka Institute for wheat named by V.M. Remeslo UAAN new winter-hardy winter wheat variety material was obtained. The annual breeding was used for the selection df winter wheat forms from spring wheat varieties by the prevernalization, spring sowing and M2 at the beginning of optimal terms in autumn (the influence of low temperature on spring wheat seeds). On the basis of such material, winter-hardy wheat varieties were created, such as Myronivs’ka rannyostygla, Remeslivna, Vo- loshkova and such varieties as Bagira, Vdyachna and Svyankova were submitted to the State Service for Plant Variety Protection.

The study of impact of complex application of biological compositions based on fixing nitrogen by microorganisms and plant lectin and nitric fertilizers on productivity and quality of grain of winter wheat on the dark-grey soil in the field terms was conducted. It is shown, that presowing treatment of seed by biological compositions stimulated forming of greater productivity with the best quality.

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.

Бажаємо Михайлові Васильовичу здоров’я та нових здобутків у розвитку аграрної науки на користь суспільства і на радість людям.

The author has investigated the acclimation processes of the apple cultivars Ascolda and Spartan on nine clonal rootstocks bred in Ukraine. The degree of different tissues frost-resistance has been terminated and the acclimation processes in one - year germinations estimated. The cul- tivar-rootstock combinations have been selected which are the most adapted to the hibernation conditions under the conditions of the Ukraine’s northern.
