The variety belongs to the first class of seedlessness; seeds are absent or represented by small rudiments. The vines have high vigor, and the canes mature well. The period from bud burst to full maturity is 160–170 days with an active temperature sum of about 3200°С.
The clusters are conical-cylindrical, of moderate density, weighing from 200–250 g to 400–500 g. The berries are small, oval, yellowish-green or amber-yellow in color with thin skin and fleshy pulp. Productivity is high, up to 150–200 c/ha.
The variety is thermophilic, winter hardiness is –19...–21°С, and it requires covering in severe climates. Resistance to fungal diseases is low; a complex of protective measures is required. Long pruning and the use of gibberellin are applied to increase berry size.
