Variety description

10 August 2026

The variety forms a large, firm, and well-closed head. The leaves have a light green color and a moderately blistered surface. The plant is characterized by a long growing season and is considered late-ripening.

The variety is intended for cultivation in open field conditions during the summer period. It is resistant to the formation of flowering shoots, which allows for harvesting in summer, provided there is regular irrigation. Formation of the head requires a photoperiod of at least 12 hours and intensive lighting.
