In the article are presented the botanical, agrobiological and economic-technological characteristics of a new table grape variety with the working Name Pamyati Peytel (G-7-26-258), in the ecological conditions of Southern Daghestan. The hybrid form G-7-26-258 obtained by crossing the varieties Nimrang x Agadai, belongs to the group of varieties of the middle-late ripening period. The duration of the growing season is 140 days with the sum of active temperatures 2980 º. Bushes of great growth, annual shoots ripen by 90-95 %. The cluuster is large, cylindrical, of medium density and dense. The berry is large, flattened, slightly lobated, light yellowish. The skin is of medium strength. The pulp is dense, thick-walled. The taste is harmonious, pleasant, refreshing. The seeds in the berry are two or four, more often one or three. The yield is 13-15 kg per bush. The sugar content of the juice is 161 g/dm3 , the titratable acidity is 5.9 g/dm3 . The transportability is high. Resistance to fungal diseases and pests in comparison with other tablezoned varieties is high. The variety shows tolerance to the root phylloxera, reaching a yield of more than 10 kg per bush in its own rooted culture at the age of more than 20 years against the background of overall phylloxera infestation. Winter hardiness is high, and frost resistance is sufficient for the open-earth zone of the coastal areas of the Republic of Daghestan in 2012 at -17.8 º the death of eyes was 33.2 %.

The introduction of the variety into production will contribute to the expansion of the assortment and conveyor of the Republic of Daghestan table grapes.
The data of estimation of damage degree of native grape varieties buds, breeding DBESV&O and hybrid forms as a result of influence of critical winter temperatures in 2012 in Daghestan condition are presented. The coefficient of fruitfulness of studied varieties is determined and varieties with high degree of winter hardiness are revealed
