Variety description
10 August 2026
The plant is a vigorous vine capable of reaching a height of more than 10–20 meters. The leaves are heart-shaped, typically three-lobed with sharp serrations along the edge. The root system is thin, highly branched, and located primarily in the surface layers of the soil.
The variety possesses high resistance to phylloxera, downy mildew, and powdery mildew; however, it is sensitive to chlorosis on soils with high lime content. Due to small, sour berries, unsuitable for industrial consumption, the form is used exclusively as a rootstock for grafting European grape varieties.
