Variety description

10 August 2026

The hybrid's vegetation period is 130–150 days; with direct sowing, it can reach 150 days. The head shape varies from round to high-round. At a standard planting density of 21–28 thousand plants per hectare, the average head weight is 5.0–7.0 kg; with sparse planting, the weight can exceed 8 kg.

The head has a very dense internal structure with thin leaf layers, which ensures a high yield of finished product. The hybrid is primarily intended for fermentation, allowing for a white-colored product with a fine structure; it is also suitable for short-term storage. The hybrid was created based on the Alfama variety specimen.
