The white grape variety is a complex new variety between Merzling x GM 6493. Synonyms and breeding numbers are Freiburg 240-75 and FR 240-75. 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). Plant variety protection was granted in 2001.

The Solaris variety was a crossing partner in the eight fungus-resistant new varieties Cabernet Cantor, Cabernet Carol, Cabernet Cortis, Calardis Soleil, Galante, Monarch, Muscaris and Rosina (1).
