10 August 2026
The Halewyn RZ variety belongs to the butterhead lettuce type and is intended for greenhouse cultivation during the autumn, winter, and spring periods. The plant forms heavy, large heads of light green color with a dense leaf structure and a firm base, which ensures convenience during crop packing.
The variety possesses resistance to downy mildew (Bremia lactucae) races 16–31, 34, 36, 39, 40. It is also characterized by high resistance to tip burn, glassiness, bottom rot, and has a low susceptibility to premature bolting.
