Rondo grape
From Wikipedia, the free encyclopedia
Rondo is an hybrid red grape variety, used for making wine. It is an inter-specific crossing between the varieties Zarya Severa and St. Laurent. It was crossed in 1964 by Professor V. Kraus of Czechoslovakia. He offered it to Dr. Helmut Becker (1927-1990) of the Geisenheim Institute (Forschungsanstalt Geisenheim), who conducted further research on it. The variety has been protected since 1997.
This very early maturing variety possesses high resistance against winter frost and downy mildew from its Asiatic Vitis amurensis parent. However annual treatments against powdery mildew may still be necessary. It produces a ruby-red wine which is also used for blending. Rondo is cultivated in Denmark, England, in Rheinhessen, and in the Netherlands.
