An early cider variety, a cross between Muscat Ottonel and Prachtraube (sometimes abbreviated MOPR). She was bred in Polešovici by Ing. V. Křivánek. It was entered in the State Variety Book in 1987.
It produces fine, muscat and floral wines with lower acidity. The taste is fruity, fresh and soon harmonious, which is why it is used for the production of St. Martin's wines.
