The variety is the result of crossing Ontario and Thompson Seedless (Kishmish belyi). The plant is vigorous, with shoots maturing well. Clusters are conical in shape, medium-sized, with density ranging from moderately loose to dense.
Berries are medium-sized, round, green-golden in color, and contain seed rudiments. The taste is sweet, with a pineapple-strawberry or mango flavor. The variety is intended for fresh consumption, as well as for making jelly and juices.
The plant possesses resistance to downy mildew and powdery mildew. Frost resistance is estimated in the range of up to -23...-27°C, which allows the variety to be grown in regions with a cool climate.
