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.

The studying results of drought resistance for 15 varieties and 6 forms of apricot in the condition of South of the Ukraine have been given. The plants with different level of drought resistance have been selected from apricot varieties and forms introduced on the South Coast of the Crimea. From the studied varieties the most drought resistance ones are: Vardaguin Vagdaas, Luchak Sumbarskiy, Sulina, LE-132. Two best apricot varieties have been recommended for use in selection on this character

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.

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.

It is presented the description of garden pea new varieties which are included into the State Register of plant varieties, which are suitable for the dissemination in Ukraine in 2008 year, morphological features of the crop and its value, either food or dietetic plant.

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.

Results of four-years assessment of approximately 90 winter wheat varieties at post- registration research on the background of crops chemical protection and in its absence at Biloczerkivska DSDS (forest- steppe zone) and Borodianska DSDS (subforest zone) are represented in this article. Methods of their immunological assessment and determination of potential productivity have been developed too. Authors are recommending to conduct immunological assessment of varieties on their natural background of diseases development and assess potential productivity in conditions of plants chemical protection as this is the element of crop growing technology.

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.

Purpose. Determination of peculiarities of anatomical and morphological characters of stevia plants to accelerate the identification of tetraploid forms. Methods. Field, laboratory and analysis-of-variance methods. Results. It was established that larger leaf area index (19–38%), fewer stomata per unit area (by 39–48%), larger diameter of pollen grains (by 42–92%) is a characteristic feature of anatomical and morphological characters of stevia tetraploid forms as compared to diploid ones. Conclusions. The parameters of leaf plate, the size of stomata and diameter of pollen grains are auxiliary selection criteria (rapid test). For tetraploid forms of stevia, leaf area index (the ratio of leaf blade length to width), size of stomata and diameter of pollen grains is truly larger as compared to diploid forms. Chromosomes number determination based on cytological analysis is the major and the most accurate criterion for selection of tetraploid forms, that seems advisable to use it at later stages of selection.

The problems concerning selection of winter wheat and grain quality have been studied. It has found out the regularity of formation of technological values required in hybrid plants; questions of intensification of protein and gluten producing in grain; questions of their quality and inheritability in varieties. Key words: winter wheat, mass of 1000 seeds, protein and gluten contain, sedimentation, flour power, bread volume, heredity, selection steps, falling time.
