Variety description

10 August 2026

The tree has weak to medium vigor, with a tendency to form pendulous branches and good branching. Requires careful pruning for proper formation of fruit-bearing wood.

The fruits are heart-shaped, 27–30 mm in size and 11–13 g in weight. The skin is dark red, almost black, with a strong luster; the flesh is juicy, firm, with a sweet taste and harmonious acidity. The long pedicel facilitates harvesting.

The variety is self-incompatible, belonging to sterility group 17 (genotype S4S6). The variety is characterized by high regular yield, high resistance of foliage to diseases, and low sensitivity to fruit cracking.
