Abstract
Rootstock variety `Borner` is a cross between Vitis riparia 183G×Vitis cinerea Arnold. The new variety was obtained by traditional grapevine crossbreeding techniques. The basic idea for the choice of the two breeding partners was to combine the positive viticultural characteristics of Vitis riparia with the complete phylloxera resistance potential of Vitis cinerea.
