Synonym (also Rizling Rajnski, Ryzlink Rýnský) for the grape variety Riesling; see there.
The white grape variety probably originates from Germany. There are more than 150 synonyms, which testify to its great age and worldwide distribution in almost all wine-producing countries. The most important ones, grouped alphabetically by country, are Risling (Bulgaria); Edler Riesling, Gelber Riesling, Gräfenberger, Hochheimer, Johannisberger, Kleinriesling, Klingelberger, Rissling, Rüsseling, Weißer Riesling (Germany); Raisin du Rhin, Rhin, Riesling Rhénan (France); Riesling Renano (Italy); Rajinski Riesling (former Yugoslavia); Rizling Rajnski (Croatia); Rislinoc (Moldova); Rheinriesling, Ritzling (also Riedenname), Weißer Riesling (Austria); Riesling de Rhin (Romania); Johannisberg, Johannisberg Riesling, Petit Rhin (Switzerland); Rizling Rýnsky (Slovakia); Renski Rizling (Slovenia); Lipka, Ryzlink Rýnský, Starovetski (Czech Republic); Beyaz Riesling (Turkey); Рислінг, Rislinok (Ukraine); Fehér Rajnai, Rajnai Rizling (Hungary); Rhine Riesling, White Riesling (California-USA).
According to DNA analyses carried out by Dr. Ferdinand Regner in 1998, Riesling originated from a presumably natural cross between (Vitis vinifera sylvestris x Traminer) x White Heunisch (Gouais Blanc). The small berries and frost hardiness come from the wild vine, the spicy notes from Traminer and the Heunisch brought late ripeness, robustness and acidity potential. It should be noted that although Gouais Blanc, the involvement of wild grapevine and Traminer is not certain. According to the latest DNA analysis in 2021, it is a cross between an unknown parent variety x Gouais Blanc. According to DNA analyses, the rare variety Red Riesling is not a precursor but a mutation of White Riesling and the variety Blue Riesling descends from Traminer. Due to morphological similarities, the White Riesling must not be confused with the Crouchen, Menu Pineau, Pedro Ximénez, Räuschling or Sauvignonasse varieties. There is no genetic relationship to Welschriesling (Graševina), whose parentage, however, is unknown. The prestigious name Riesling has often been used misleadingly and partly abusively worldwide:
