Characteristics of newly created grapevine varieties Vozd and Vladun

This paper presents the most important morphological and production-technological characteristics of newly created grapevine varieties Vozd and Vladun, intended for the production of red wines. The newly created varieties were compared with the standard variety Cabernet Sauvignon during the three-year period of testing (2015-2017) in the relation studied properties. The variety Vozd obtained from the crossing combination Zacinak x Prokupac, and the variety Vladun from the crossing combination Merlot x Zupski Bojadiser. The investigated varieties differed considerably in terms of some morphological traits and represents unique genotypes. The newly recognized varieties have a hermaphrodite type of flower, dense bunch, globose berry shape and blue black color of berry skin. The yield, bunch weight, bunch length and bunch width were higher at both varieties than for the standard variety. The Vozd variety had a yield of 1.29 kg/m2 and a bunch weight of 174.3 g, and the Vladun variety had a yield of 0.87 kg/m2 and a bunch weight of 153.7 g. For the standard variety the grape yield was 0.78 kg/m2 and the bunch weight was 134.0 g. The content of sugar and total acids in the must of the Vozd variety was 20.5% and 6.5 g/l, while for the Vladun variety it was 21.8% and 6.0 g/l respectively. Wine of both varieties was drinkable, harmonious, with a specific varietal of smell and taste and contained 12.1 vol. % of alcohol (Vozd variety), or 12.6 vol. % of alcohol (Vladun variety). Due to the many positive features of the grapes and wines from the Vozd and Vladun varieties, their spread to the production vineyards of Serbia is expected.
