Variety description

10 August 2026

The fruit bodies of this hybrid have a rounded, dense cap with a diameter of 4–6 cm and a sturdy stalk, which ensures suitability for both manual and mechanized harvesting. The yield of the variety reaches 20–28 kg/m², while the uniform distribution of flushes allows for an extended harvesting period.
