The white grape variety is a new breeding between Riesling x Madeleine Royale. Some synonyms point to the parentage Riesling x Sylvaner, which was wrongly assumed for a long time. Within the European Union, those names that refer to it, such as Riesling-Sylvaner, are no longer permitted. The most important are Müller-Thurgau Rebe, Müller Thurgau Weiß(Germany); Müller-Thurgau Blanc (France); Uva di Lauria (Italy); Riesling-Silvaner, Riesling x Silvaner, Riesling-Sylvaner (New Zealand, Switzerland); Rivaner (Austria, Luxembourg), Rizlingszilvani (Hungary), Rizvanac, Rizvanac Bijeli (Croatia); Rizanec, Rizvanec (Slovenia); Muller Thurgau White (USA). Due to its characteristics, it is a popular crossing partner of new varieties. These are among others Albalonga, Arnsburger, Bacchus, Diana (1), Faberrebe, Floriánka, Fontanara, Gloria, Goldriesling (2), Grando, Gutenborner, Helios (1), Hildegardistraube, Kanzler, Mariensteiner, Markant, Medea, Mília, Montagna, Muscabona, Muscat Bleu, Optima, Ortega, Pálava, Perle, Rabaner, Regner, Reichensteiner, Schantlrebe, Septimer, Tamara, Thekla, Thurling and Würzer. Two mutations are Findling (earlier ripening) and Roter Müller-Thurgau (berry colour).
