Variety description

10 August 2026

The variety belongs to the group of ultra-early hybrids with a maturity period of 40–45 to 55–60 days after transplanting. The plant is intended for cultivation in open field and protected cultivation. The crop is characterized by plasticity and a developed root system, while the rosette itself does not possess high growth vigor.

The heads have a conical shape, their weight varies from 0.8 to 2.1 kg with average density. The wrapper leaves are green, and the inner ones are light green. The hybrid demonstrates uniformity of fruit, however it requires protection from pests.
