The white grape variety (also FR 240-75) is a complex new breeding between Merzling x GM 6493(Zarya Severa x Muscat Ottonel). It contains genes from Vitis amurensis, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1975 by Norbert Becker (1937-2012) at the State Viticulture Institute in Freiburg (Baden-Württemberg). The plant variety protection was granted in 2001. The Solaris variety or its initial plant population was the crossing partner in the six fungus-resistant new varieties Cabernet Cantor, Cabernet Carol, Cabernet Cortis, Galante, Monarch and Muscaris.
The early ripening vine is generally well resistant to fungal diseases, but especially to downy mildew. It is therefore even recommended by the PIWI-International working group. The variety produces strong, acid accentuated white wines with pronounced fruitiness. It is particularly suitable for northern conditions. In Germany it occupies 66 hectares of vineyards, 37 of which are in Baden. In mid-2009, the Rheingau-based Balthasar Ress winery planted Solaris vines on the North Sea island of Sylt Solaris, which belongs to Schleswig-Holstein. There are also small stocks in Belgium, Denmark, Italy, Sweden, Switzerland (13 hectares) and Norway. In 2010, a total of 86 hectares of vineyard area were designated (statistics Kym Anderson).
