The variety is an interspecific hybrid obtained by crossing the Malbec variety (Vitis vinifera) and the species Vitis berlandieri. It is used exclusively as a rootstock for grafting cultivated grape varieties.
The economic value of the rootstock lies in its adaptation to calcareous soils, inherited from Vitis berlandieri, and resistance to phylloxera, characteristic of American grape species.
