Results of systematization and morphological characteristics of two wheat species-bread (Triticum aestivum L.) and hard (Triticum durum Desf.) are given. Detail descriptions of 55 main varieties of bread wheat and 32 varieties of hard wheat arep- resented in table version. In practical application these result enable plant breeders, seed producers and variety testers to determine wheat varieties easily sinse it is method for morphological systematics of wheat.

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 peculiarities of ice-forming in the stems of 7 cultivars and forms of blackberry have been determined by means of the differential thermal analysis. The authors have established the possibility of controlling the acclimation and loss of frost- resistance by tissues caused by dehydration. The control is possible on the basis of the data about exothermal processes in the tissues.

Indicators of the morphological signs of type of sort on white cabbage plants Dutch flat, Belarus, Amager, Langendijker winter and their variability are the presented. It is established low and average factor of a variation at the majority of the morphological signs. Strong high-quality and ecological variability of signs “height external rake” and “its size leafy parts” at type of sort Dutch flat is defined.

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.

Results of research on application of plant growth regulators in cultivation of Onion Napiform from seeds in non-irrigated grain-vegetable crop rotation of Northeast Forest-steppe of Ukraine. Efficiency of seeds presowing damping was established, in the solutions of preparations Baikal EM and Emistim С and in the solution of preparation Emistim С for double use - of seeds presowing damping and of plants spraying in 5-6 leaves phase.

The article deals with agronomic characters of sugar beet MS hybrids developed on the basis of parental components with resistance to Fusarium rots during vegetation period, which were found in studies with the ecological variety test of Be- taintercross. Possibility of combining high productivity and disease resistance in one genotype was confirmed as matter of principle.

There has been studied impact of main productivity components (number of spurs, peduncles, flowers, ovaries and average berry weight) on formation of Strawberry yield of introduced varieties and varieties and hybrid forms of national breeding. It is established that high Strawberry yield in the crop of first fruit-bearing year is caused by not less than 9 spurs, 14 peduncles, 153 flowers, 115 ovaries per linier meter and average berry weight over 18 g.
