Variety description

10 August 2026

The nuts of the variety have an elongated shape, slightly compressed on the sides, and are characterized as medium-small. The variety is distinguished by high yield and good taste qualities, and is often used as a pollinator for other hazelnut varieties.

Phenological features include very early flowering of female flowers in late November and early bud burst in mid-February, which increases the risk of damage by spring frosts. It is used as a parent form in breeding.
