Variety description
10 August 2026
The plant belongs to the multi-leaf butterhead lettuce type and has an upright habit, which allows it to be used for mechanized harvesting. The variety forms firm leaves that, upon a single cut, divide into many ready-to-eat parts.
The variety possesses the Knox trait, which reduces the risk of cut surface browning and increases the shelf life of the produce. The plant is characterized by good adaptability to growing conditions and excellent performance in field cultivation.
