The variety is a phylloxera-resistant rootstock possessing high vigor; shoots reach 3.5–4 meters in length. The vegetation period is approximately 180 days; the flower is functionally female. Berries are small, black with a bluish tint; bunches are small and loose. The variety is not intended for commercial harvest production.
It is characterized by high resistance to fungal diseases, high frost resistance (buds down to -30°C, roots down to -9°C), and drought tolerance. It tolerates soils with total carbonate content up to 35% well. Cutting rooting ability is satisfactory; callusing is often applied.
The variety demonstrates good graft compatibility with most scions. Due to a pronounced stimulating effect on scion growth, a slight delay in harvest ripening may sometimes be observed.
