The rootstock ' Geisenheim 26 ' comes from the early days of rootstock breeding and belongs to the group of Vinifera x American crosses. The aim of this cross was to improve the compatibility of the rootstock with the European varieties. This was achieved, but the phylloxera resistance decreased very much. Because of the insufficient resistance to the root aphid , it is no longer used as a rootstock.
ancestry
Cross of 'Schiava grossa' (Syn. ' Trollinger ') × Vitis riparia at the " Plant Physiological Experimental Station " in Geisenheim am Rhein.
