Variety description

10 August 2026

The Grewger variety forms a rosette of uniform, dense, rounded, and crunchy leaves. The plant features strong, elastic, and non-hollow petioles, which minimizes damage and browning during harvesting and logistics.

The variety is versatile and adapted for cultivation throughout the entire season. It possesses pronounced resistance to downy mildew (Bremia lactucae), including a wide spectrum of modern races (Bl: 16–21, 23–26, 28–37EU and 29–41EU).

The variety is intended for the "Salad Burger" segment, ideally suited for preparing burgers and sandwiches. Its characteristics contribute to reducing waste during processing due to leaf uniformity and a high capacity for maintaining shelf life.
