The variety is a complex intraspecific hybrid obtained from crossing Cardinal and Sultana varieties. It belongs to the first class of seedlessness and contains only inconspicuous rudiments. The bunches are conical in shape, their weight ranges from 400 to 700 g, and the bunch density is medium to high.
The berries are medium-sized, round, with a weight of 3–4 g. The variety is characterized by an early ripening period (110–120 days). The bushes possess high vigor. The berries are well-transportable and suitable for long-term storage, as well as for the production of dried products.
The variety has low resistance to major fungal diseases and low winter hardiness, requiring covering at temperatures below -15...-18°C. Agrotechnology includes the use of gibberellin to increase berry size.
