Rondo

The red grape variety (also GM 6494-5) is a new breeding between Zarya Severa x St. Laurent. Synonyms are Ambros Rot, Geisenheim 6494-5 and GM 6494-5, and genes of Vitis amurensis and Vitis vinifera are included. Although it is clearly a hybrid from a botanical point of view, it is not considered as such. Strictly speaking, these are prohibited within the EU for quality wines and local wines. In 2003, a study was carried out on behalf of the European Commission to establish criteria for the assessment of "hybrid or non-hybrid". The variety was classified as a "non-hybrid" among several other new breeds with amurensis genes carried out in Germany. The basic crossing of the underlying variety was already done in 1964 by the breeder Vilém Kraus (1924-2013) in the former Czechoslovakia. This breeder later offered some vine seeds to Dr. Helmut Becker (1927-1990) in Geisenheim, who recognized the importance of the breeding material. From this seedling population, which was then called GM 6494, the seedling 6494-5 was selected due to its performance and later propagated under the variety name Rondo as an independent grape variety. Plant variety protection was granted in 1997. The variety was a cross-breeding partner for the new varieties Allegro and Prior.
