Divona, new white grape variety
The first white grape variety bred by Agroscope that is resistant to both downy mildew (Plasmopara viticola) and powdery mildew (Erysiphe necator) and which boasts low susceptibility to grey mould (Botrytis cinerea) has just been approved. The outcome of a cross of Bronner and Gamaret carried out in 1997, this variety was named Divona as a tribute to a Celtic fountain goddess. Its resistance to disease – not far short of Divico’s – is high, although not absolute. Depending on disease pressure, one to three phytosanitary treatments applied around the flowering/fruit-set period are sufficient for effective protection. This grape variety displays a fairly high productivity which often requires harvest regulation. Divona is an early variety that ripens at the same time as Müller Thurgau, so the warmest spots in the vineyard should be avoided. The wines obtained from the grape are structured and highly esteemed at tastings; their bouquet can be fairly complex (exotic fruits, citrus fruits, floral notes, mineral notes upon ageing).
