The white grape variety (also Dánosi Leányka) originates from Hungary; the name means "royal girl = princess. It must not be confused with the Királyszölö variety. The exact origin is not yet clear. According to one hypothesis, it originated from a cross between Kövérszőlő(Grasă de Cotnari) x Leányka. According to a second hypothesis, it is identical to the Fetească Regală. In both cases, this would be a Romanian origin. DNA analyses carried out in 2009 disproved these hypotheses, but Leányka could be a parent. The medium-maturing, high-yielding vine is susceptible to botrytis and downy mildew. It yields fresh, low-alcohol white wines with moderate acidity and a floral aroma. These are very popular in Hungary as so-called typical summer wines. It is often used as a blending partner to introduce acidity. The variety is widespread in Hungary at Lake Balaton (Plattensee), as well as in the areas of Eger, Etyek-Buda and Mátraalja. It occupied a total of 784 hectares of vineyards in 2016 (Kym Anderson).
