Germany, grapevine breeding

There are six grapevine breeding centres in Germany: Alzey in Oppenheim, Freiburg in Baden Württemburg, Geilweilerhof (the Julius Kühn Institut), Geisenheim (in Hessen, but also partly sponsored by Rheinland-Pfalz), Weinsburg (in Baden-Württemburg), and Würzburg in Bayern (Bavaria).

Geilweilerhof is the only grapevine breeding centre which is federally funded. It conducts breeding and breeding research only. The other institutes are funded by the German states and perform practical trials and extension work for growers in the regions, but not breeding. Geilweilerhof has contracts with nurseries in every Germany wine region, and propagates cuttings for replanting and sale. Half the sales price covers the harvesting of the cutting and the other half is royalties.

Examples of disease-resistant grape varieties or PIWIs bred in Germany include Regent and Rondo for red wines, and Phoenix, Orion, Johanniter, Sirius, Solaris and Saphira for white wines.
