The study of vernalization requierement of winter bread wheat 87 modem varieties from Ukraine and Russia showed significant domination - 81.6% - of varieties with short vernalization requierement (30-40 days). Vernalization requierement differences among varieties from different climatic zones were revealed.

Morphological and cultivation value characteristics description of new perspective ornamental peach varieties bred in Nikita Botanical Gardens has been given. The varieties were bred as a result of using genoplasm Persica vulgaris Mill, varieties with different type of flower, P. mira (Koehne) Koval, et Kostina and Amygdalus communis L. They differ in high ornamental idices in flowering period and in bioecilogical indexes.

Creation of Initial raw for breeding of winter wheat by change of the development type under low temperatures influence was described. Seeds of spring wheat were vernalized in aluminum weighting bottle. By using low temperatures at sawing of M2-6 at the begin ind of optimal terms of sawing of winter wheat, new winter-hardy variety of Voloshkova was bred.
