disease-resistant varieties, semantically expedient term for grapevines introduced by the German Bundessortenamt (Plant Variety Rights Office) in 1995 that were bred specifically to produce wines that taste like vinifera yet meet consumer demands for reductions in agrochemical use by incorporating some non-V. vinifera genes for resistance to various common vine diseases. The term replaces the previously pejorative terms hybrids or interspecific hybrids for some of their most promising results of vine breeding. The German term is Pilzwiderstandsfähige Rebsorten.
