Descent
Norbert Becker took to the intersection of this variety the parent varieties Merzling as mother and Gm 6494 as a father. Gm 6494 (or Geisenheim 6494 ) was a Sämlingspopulation, which was crossed in 1964 by Professor V. Kraus in the former Czechoslovakia from the varieties Zarya Severa x St. Laurent. Prof. Kraus provided the seedlings Prof. Dr. Helmut Becker (1927-1990), then at the Geisenheim Research Institute operates at who recognized the importance of this material and it continued to work on breeding in progeny tests. From Sämlingspopulation 6494 Gm Gm was the seedling 6494-5 read due to its special performance and later propagated under the varietal name Rondo as a separate variety and brought into practice.
Norbert Becker researched at the crossroads of Prof. V. Kraus in 1964 for the Sämlingspopulation who had received the designation 6494 Gm only in Geisenheim, mistakenly vine Saperavi Severni instead Zarya Severa as a mother places ♀. A differentiated rechecked by N. Becker's successor Volker Joerger together with colleagues from the Geisenheim Research Institute was able to show the error and the true parenthood now applies in professional circles since 2003 as a secured clarified. However, these findings could not be included in the 13th edition of the Handbook of grape varieties.
