The variety is a hybrid of Gold and Q25-6. The plant is characterized by very vigorous growth and requires long pruning of 10–12 buds due to low fertility of the basal buds, which makes it suitable for arch training systems. The ripening period is 115–130 days.
Clusters are large, conical in shape, of medium density, weighing from 400–500 g to 1 kg. Berries are yellow-green in color, oval or elongated-oval in shape, weighing 3–8 g. The skin is thin and edible.
Resistance to downy mildew and powdery mildew is assessed as average or below average, requiring preventive treatments. Frost resistance is -21...-23°C; the variety requires winter covering. Transportability of the fruit is limited; loss of marketability is possible during storage.
