Term for modern varieties, from the middle of the 19th century and reinforced in the 20th century with breeding intention targeted by the manual crossing of selected parental grape varieties and by controlled seeding of the sexually fertilized seeds and after several years of testing seedlings selected, named and introduced to the market (the operation is under crossing and breeding described). Relatively little is known about the origins of the traditional old varieties, which are mostly caused by spontaneous (natural) but also man-made manual crosses. Records about it are inaccurate, often contradictory and descent can only be elaborate DNA analysis be determined. In new breeds, however, breeders, breeding year, parents and tested properties are accurately documented. The main objectives are in addition to claiming high quality vines with certain quality characteristics the resistance against pests and diseases such as PIWI = Fungal resistance, thereby reducing the use of chemical Pesticides to be able to reduce.
