Rayon d’Or

The white grape variety is an interspecific new variety between Seibel 405 (Seibel 14 x Ganzin 1) x Seibel 2007 (Aramon du Gard). Synonyms are Feherek Kiralya, Roi des Blancs, Seibel 4986, Toth Lajos, Zlatni Luc and Zokoy Loloutch. Genes of Vitis aestivalis, Vitis rupestris and Vitis vinifera are present. The hybrid was crossed at the beginning of the 20th century by Albert Seibel (1844-1936). It was a crossing partner of the new varieties Duna Gyöngye, Saphira, Seyval Blanc, Seyval Noir and Vidal Blanc. The early-maturing vine is resistant to both powdery mildew and black rot, but susceptible to anthracnose. At the end of the 1950ies, it still occupied about 7,000 hectares at the Loire; due to the ban on hybrids in the meantime, this has shrunk to six hectares. Small populations exist in the US states of Missouri, New Jersey, Ohio and Pennsylvania, as well as in Canada, but only French populations were designated in 2016 (Kym Andderson).
