Vitis divided into a European, Asian and American group. In America, around 30 wild species are recognized. All have 19 pairs of chromosomes (2n = 38). The second only in America occurring Vitis subgenus Vitis subg. Muscadinia has another DNA structure with 20 chromosome pairs (2n = 40). There is only one Muscadinia species (with three varieties) whose correct name should be Muscadinia rotundifolia . But it is mostly as Vitis rotundifolia designated.
Although Muscadinia plays no special role in wine production, it is due to its resistance against phylloxera and nematodes for the breeding of new grape varieties and documents interesting and sought after. The different chromosomes mean at intersections big problem. A negative feature of some American vines specifically for the European palate is strawberry flavor and Foxton, This is especially true of the Vitis labrusca and Vitis rotundifolia to.
