Variety description

10 August 2026

The strain is characterized by the white color of the fruiting bodies with a smooth surface. In the breeding process, parent cultures are selected based on specific interaction with compost and biochemical markers in the vegetative phase. The mycelium is grown on rye.

This strain is specialized for industrial processing and differs from varieties intended for the fresh market. Available information lacks data on precise ripening periods and disease resistance indices.
