It’s belong to the group of Black see pool varieties on morphologic-physiological characteristics (convar. pontica subconvar. balcanica Negr.). The variety is used for making dry red wines of excellent quality. It is very perspective variety in Southern zones of Europe where the grape couldn’t get good acidity in the juice of berries
In article there are new modern technologies of using young vineyards, which help to give higher growth of roots and shoots, higher degree of life and coming in full fruitless in time. It is the most fast and easy method of using tendril, clips and forcing of wires of the system Gripple [3].
In the article color photos of perspective grades of grapes of the North Caucasus, having valuable characteristics for their use for production workers of the south of Russia and selectors as initial forms are presented. These grades are certified as perspective on the basis of long-term studying by originators and statements of Gov. sort committee of the Russian Federation after insertion into the State sorts book
In the article the short description of theoretical bases of vine bushes trimming, ways of trimming, methods of setting the optimum loading of a bushes when trimming, optimum terms of trimming young and fructifying plantings, key rules and techniques of trimming of bushes are specified
In the article the innovations developed by the department are presented. The short characteristic of the basic forms of the bushes applied at vineyards in zones of uncovered, conditionally covered and covered vine growing is given. New energy and resource saving technologies of cultivation of grape are examined
In innovational section the results of researches of application of “RADIKS” biologically active substance are presented at prelanding processing of cuttings and desktop inoculations on an amount and quality of own-rooted, imparted and vegetative grapes saplings
The grade of grapes "Academician Eryomin" is introduced in Greece by P.Zamanidi and L.Troshin in 2002 by crossing of Greek Trapsa grade with French Alikant Bush.
