10 August 2026
The hybrid heads have a round or round-oval shape and are white in cross-section. The plant forms medium-sized wrapper leaves, which are characterized by a gray-green color, blistered structure, and the presence of a waxy bloom.
The hybrid has high resistance to Fusarium wilt and thrips infestation, and is resistant to climatic fluctuations. The heads are capable of maintaining their marketability in the field for a long time without cracking and are well-suited for transportation.
The produce is suitable for storage for 4–5 months. During long-term storage, the heads can accumulate sugars, which makes them suitable for sauerkraut production.
