Prüfung neuer pilzwiderstandsfähiger Rotweinrebsorten auf ihre Anbaueignung in Franken

Summary

Five new fungus-tolerant grape varieties were tested from 2005 to 2010 in comparison to Merlot in Franconia/Germany. Crossings with Cabernet Sauvignon showed different ripening behavior, and aroma expression. Cabernet Carbon presented a full-bodied wine, whereas Cabernet Coral ranged sensorically near his cross parent Cabernet Sauvignon. Reberger as a very early ripening variety reached often plumy notes. All 5 varieties are not totally fungus resistant and need some plant protection depending on the yearly infection conditions. In specific years the tested Cabernet crossings had problems with stem dieback and bunch rot. Cabernet Carol and Cabernet Cortis reached the best results in relation to Merlot.
