The perspective hybrid forms between genus Prunus persica (L.) Batch and Prunus amygdalus Batsch, having high ornamental qualities and high resistance to Sphaerotheca pannosa (L v.) var. persicae Woronich., Taphrina deformans (Berk.) Tul., Clasterosporium carpophilum (L. v) Aderh., Monilia cinerea Bonord. have been obtained for using in breeding of peach and nectarine varieties and their rootstocks.

On the basis of literary sources history of origin and development of agriculture is rotined in Ancient. The first Civilizations arose up on fat streamside lands of the large rivers: Nile, Euphrates, tiger, Inda, Ganga and other Earths and plenty of water are fertile during an overflow, a warm climate allowed to Ancient civilizations to grow 2-3 harvests in a year. For the receipt of high harvests, a man had to study the modes of overflow of the rivers, look after heavenly bodies, determine the areas of scopes and terms of leadthrough of the field works. The decision of these questions resulted in the origin of agronomics, astronomy, mathematics. Large harvests were instrumental in the origin of peculiar, enriching of the states, to development of trade and culture on the whole. Riches of country and overpopulation resulted in the origin of wars which one states perished as a result of, second – blossomed. Scientists consider that a high culture, intensive exploitation of soils and aggressiveness of man, brought the most Ancient Civilizations over to the ecological crisis and their elimination.

The estimation of drought hardiness of sea buckthorn varieties of different environmental and geographical origin was made in the field and laboratory conditions. In late August the drought hardiness was estimated according to leaf injures and abscission in the field conditions. In the laboratory conditions were determined the main characteristics of water regime: tissue water saturation, water deficit, leaf water retaining ability. As a consequence, the studied varieties were divided into groups with different drought hardiness degree.

The article researched genetic potential, morpho-biological characteristics and features of new varieties of winter wheat varieties of semi-dwarf and short-stem types. It was established that new generation of such varieties displayed improved architectonic of plants, as well as a complex of morphological and economical value chararacteristics and features, combined high genetic potential of productivity with good adopting features, and short stem with high resistance to drowning, and generated higher crop capacity compared to conventional mid-ripening varieties.
