PROMISING NEW HIGH YIELDING VARIETIES OF GRAPES
The high productivity and quality of a crop are the main priority objectives in the grapes breeding. The selection of donors and sources with positive qualities among varieties, collected in one agric-ecological zone and on one plot, significantly facilitates this task. Ampelografic collections have considerable impact on formation and enrichment of industrial assortment in the areas of the developed wine growing and wine-making, therefore the research work on an ampelografic and the varieties description are important and actual. We selected five technical grapes varieties which show the high productivity and quality of a crop during several years. Their frost resistance in 2006 and 2012 and the high crop capacity in 2006-2011 and 2013 put them in a row of the perspective varieties. Ariatika grapes has the average term of ripening, it is endures the frosts to -21C °. Resistance to diseases and wreckers is average. Productivity is high. The Vaznisubishavi grapes has the average term of ripening, it endures the frosts to -25C °, for the winter it doesn't take a cover. Resistance to diseases and wreckers is average, the productivity is high. Stepnyak grapes has middle early term of ripening, it is endures the frosts to -25C °. Resistance to diseases and wreckers is high, the productivity is high. Bakator white has the early term of ripening, it endures the frosts to -25 C°. Resistance to diseases and wreckers is high, the productivity is high. Cosmopolita grapes has a very early term of ripening, it endures the frosts to -20C °. Resistance to diseases and wreckers is high, the productivity is high. The grapes varieties selected in a collection can be recommended as donors and sources of useful traits.
