Dacicus, new grape cultivar for white wines, with genetic resistance to cryptogamic diseases

Abstract

In the context of the current global and zonal climate changes, the practice of sustainable viticulture by capitalizing on the ecopedoclimatic conditions specific to each viticultural area and reducing the amounts of pesticides applied through phytosanitary treatments, requires the obtaining and promoting practice of new vine cultivars with complex biological resistance, with qualitative potential and superior productivity, with good tolerance to biotic and abiotic stress factors. To respond to this desire, at R.D.S.V.O. Odobesti, using the direct sexual hybridization between the cultivar ‘Traminer roz‘and the interspecific hybrid ‘Isabelle‘, was obtained and approved in 2022 the ‘Dacicus‘ cultivar. This new creation is characterized by medium to large sized grapes (227 g), with medium sized berries (1.64 g), with pink skin, and more intense on the sunny side. The pulp is juicy, with low firmness, without anthocyanin coloration. The average production of grapes is 6.10 kg/vine, respectively 23.0 tons/ha. It presents high biological resistance to the main cryptogamic diseases. The grapes reach full maturity in the 5th epoch. From this cultivar one can obtain high-quality white wines, dry or semi-dry, with a slight aromatic tinge, with high alcoholic potential (12.7 – 13.9 vol % alcohol), a total acidity of 5.9 – 6.5 g/L tartaric acid and a high values of the non-reducing dry extract (19.8 - 23.6 g/L).
