Breidecker is a white wine variety that was crossed in 1962 by Heinrich Birk at the Geisenheim Research Institute in Geisenheim from Silvaner x Riesling and Chancellor . The largely fungus-resistant ( powdery mildew and downy mildew of the grapevine ) was named after Hans Breidecker, who made it popular in New Zealand . In 2007, the area under vines was still stagnating at 9 hectares . In the literature, the Müller-Thurgau variety is often mistakenly stated as one of the parents. Due to the use of the Chancellor variety, the variety is a hybrid vine from European and American parents; in Germany it is only approved for trial cultivation. In addition to New Zealand, plantings are also known in Canada and the USA .
