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.

The infection by phytoviruses and the productivity formation in the new varieties of winter bread wheat in the different years with virus damage were investigated. There were identified the varieties being more tolerant to the observed diseases, among these - the samples with different constituents of tolerance, which could be used in the breeding programs.

The fruit of apple scab immune hybrids, obtained from the targeted crossings for suitability for juice production, were estimated. The most perspective hybrids were selected. They are not inferior to the world juice cultivars in the basic technological characters (juice output), and even surpass them in a number of these characters (the content of SDS and P-active catechols in juice).

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.

History of Winter Wheat breeding rise at the South of Ukraine since the end of XIX century till the beginning of October Revolution by the example of Breeding department at Odessa Research Field is represented. Odessa Research Field was established in 1894 to study the agrotechnics of agricultural crops, in particular, Winter Wheat. The Breeding department at Odessa Research Field was established in 8th of March, 1912, and headed by Private- Docent of Novorossiysk University, A.O. Sapegin. The main procedure applied in breeding was individual multifold selection of elite ears from the existing local blends and artificial crossing of lines selected to the purpose of improving economically valuable characteristics and identifying the inheritance. Five years of breeding (1912-1917 pp.) resulted in creation of three Winter Wheat varieties: Kooperatorka (0194), Zemka (0158) and Stepniachka(0119). In 1918, the Council of People’s Commissars of USSR has parted the Breeding department of Odessa Research Field to independent Odessa agricultural breeding station recognizing development of plant varieties by the Department.

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.
