This form is used when a completely new vineyard is to be created and is widely used today. The vines in a vineyard are then genetically 100% dental, so to speak Clones, Critics of this form complain about the resulting loss of genetic diversity in such monocultures. That becomes one by using different clones vine taken into account in a vineyard. See also under breeding,
