The variety was obtained by crossing Red Globe and Princess varieties. Clusters are medium-sized, conical in shape, and of medium density. Berries are elongated-oval, narrow-ellipsoid, or cylindrical in shape, belonging to the second class of seedlessness with practically imperceptible rudiments.
The ripening period is 150–160 days. The variety has high vigor. Resistance to fungal diseases is low, winter hardiness is limited to the range of -15...-18°C. The yield is suitable for long-term storage; berries hold firmly to the pedicels.
Large berries form without the mandatory use of growth regulators such as gibberellins or ethylene.
