Pinot blanc
Confusingly, Bronner is also used as the name of an open pollination variant of Pinot blanc. The Pinot blanc-related Bronner, which is not the same variety as the 1975 German crossing, is known under the synonyms Weiße Bronnertraube and Weiße Gaman. Unlike most cultivated grape varieties, which are dioecious, Bronner/Gaman is monoecious, with only female flowers.
