The white grape variety is a new breed between Muscat Ottonel x Prachttraube. Synonyms are Moravian Muscat, Mopr (after the first letters of the parents), Mopr Blanc, Moravský Muskát and Moravian Muscat. The cross was made in 1987 in Czechoslovakia by Václav Křivánek (1927-2009). The early maturing vine is susceptible to botrytis. It yields flowery, rather low-acid white wines with muscatel. The variety has become the most widespread new variety in the Czech Republic and is cultivated mainly in the Moravian Slovácká wine region. In 2010, 351 hectares were designated in the Czech Republic and 163 hectares in Slovakia (Kym Anderson).
