Variety description

10 August 2026

The variety is a vigorous rootstock obtained as a result of selecting hybrid seedlings. The flowers are functionally male, so this grapevine is not intended for fruit production and does not form clusters.

The plant possesses high resistance to root phylloxera and nematodes, and also tolerates the presence of carbonates in the soil well up to 17–18%. At the same time, the variety is sensitive to waterlogging and water stagnation. Buds have high frost resistance down to -30°C, whereas the root system withstands temperature drops only down to -7...-8°C.

The use of the rootstock ensures increased vigor for grafted cultivars. In excessively fertile soils, excessive vegetative growth may negatively affect the quality of the scion's yield.
