Abstract
Currently, hybrid vine cultivars are not significantly used for wine making in Europe due to technological and legal reasons, nor as table grapes.
VITENERGY1 is a project finalized to the evaluation and selection of grapevine hybrid cultivars suitable for production of biomasses destined to the production of bioenergies (e.g., bioethanol, cellulose). Anthocyanins, flavonoids, flavonols and seed oil triglyceride composition of 34 grape cultivars collected from the CRA-VIT vine germplasm collection were characterized to evaluate their production of by-products useful for the food, nutraceutical and pharmaceutical industry. Seibel 8357, Burdin 4077 and Bacò 30-12 grape had very high total anthocyanins content (between 3-5 g/kg) and total flavonoids (5-6 g/kg grape). Seibel 19881, Siebel 8745 and Seyve Villard 12-347 had total flavonol contents between 100-200 mg/kg; Bacò 1 showed high percentage of unsaturated triacylglycerols, and Seibel 10878 high seed oil production.
The considerable commercial value of these bioactive compounds can play an important role in the economic sustainability of a vineyard dedicated also to production of biomass for energy uses.
