The variety is a seedless grape of the species Vitis vinifera L. and is a mutation of the Sugraone variety (known as Superior Seedless). Genetically, these varieties are almost identical, which makes them difficult to distinguish even through molecular genetic analysis.
The golden-yellow berries have a rounded shape, thin skin with bloom, and juicy, slightly fleshy sweet pulp without a specific aroma. The size of the berries is about 14–15 mm in diameter.
The cylindro-conical bunches reach a mass of 350–450 g with a length of 14–15 cm. The variety belongs to early maturity groups, with the ripening period beginning in the first ten days of July.
