Variety description

10 August 2026

The variety is intended for agricultural use as feed for dairy and beef cattle, as well as sheep. The plant is suitable for field grazing or harvesting for forage.

The plant belongs to medium or short types of forage kale with a high leaf-to-stem ratio, which provides maximum soil cover. The variety possesses resistance to lodging and high winter hardiness.

The quality of the produce is characterized by good nutritional properties and a low level of S-methylcysteine sulfoxide, which is an anti-nutritional substance for animals.
