While some of the grapes in this section are hybrids, they are hybridized within a single species (for example, Niagara). For those grapes hybridized across species, see below.
Hybrid grape varieties (see Hybrid grapes) or "hybrids" is, in fact, the popular term for a subset of what are properly known as hybrids, specifically crossings between one species of the genusvitis and another. The scientific definition of a hybrid grape is any crossing (intra- or inter-specific) of two grape varieties. In keeping with the popular definition, however, the ones listed below are inter-specific hybrids where one parent is a European grape.
