Variety description

10 August 2026

The iceberg-type plant has a compact shape and forms a dense, full, and white-hearted head with a round base. The average weight of a marketable head is about 700 grams.

The variety possesses high resistance to downy mildew (races Bl: 1–25, 27–28) and good tolerance to tip burn, as well as resistance to bolting. It is recommended for spring and autumn planting in open field conditions.

The produce is suitable for sale on the fresh market, as well as for processing in the fresh-cut packaged salad segment.
