The article reflects economical value of a valuable food crop, field pea used chiefly as a vegetable (Pisum sativum L partim), its origin and distribution both in the worldwide scale and in our country, establishment of its varietal resources. Exhausting description is provided to new varieties of pea used chiefly as a vegetable, which have been listed in the State Register of Varieties Suitable for Dissemination in Ukraine in 20010-2011 for the harvest in 2012, and for which official description is available.

The varieties and forms of nectarine resistant to fungi diseases (Clasterosporium carpophilum (Lev.) Aderh., Taphrina deformans Tul., Sphaerotheca pannosa (Wallr.) Fr. Lev. var. persicae Woronich) having the practical interest for modern technology growing and for breeding on these characteristics have been selected.

Expediency explanation is provided for foundation in the Ukrainian Institute for Plant Variety Examination of Winter Wheat Varieties Resistance to Abiotic Environment Factors Diagnostics Laboratory, as well as for examination of varieties on their suitability for dissemination to provide new approaches and techniques of plant varieties resistance diagnostics; for systematic, indepth and comprehensive studying of the most important adaptive features of plant varieties, which to take into account when registering varieties, national varietal resources formation and seed production organization.

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.

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 prospect of rapeseed production in Ukraine Discussed competition of rapeseed oil on the world market, its use for the production of alternative fuels. An assessment of the capacity of rape variety, which is listed in the State Register of plant varieties suitable for distribution in the Ukraine.

Deals with scientific activities distinguished scholar in agricultural science. His practical advice - a plan for raising farm after the October Revolution in 1917, the provision of agronomic assistance.

The article represents results of researches of 20082010 years and evaluation of the new registered and promising varieties and hybrids winter rape (seed) by their genetic potential productivity and adaptability. Changeability varieties according to high-yielding properties and elements of productivity depending with adaptability to the environmental conditions of areas of Forest, Forest-steppe and Steppe of Ukraine. There are discussed the prospects of the trends.

The pomological description of studied samples has been given; the chemical composition and relation between biochemical characteristics in fruits of Prunus cerasifera subsp. macrocarpa (Erem. et Garcov.) var. pissardi Bailey has been studied. The obtained data are compared with characteristics, typical for fruits of varieties Prunus cerasifera Ehrh. and forms of Persica vulgaris subsp. atropurpureae (Schneid.) Zajats.

Визначено рівні індивідуальної мінливості елементів технологічної якості коренеплодів у популяцій запилювачів урожайного і цукристого напрямів добору уладівської селекції. На основі генетично статистичних параметрів сформовано групу з кращих генотипів для подальшого селекційного опрацювання. Популяції У 1948-Z та У 752-E придатні для рекурентної селекції на покращання технологічної якості сировини.
