Variety description

10 August 2026

The variety is early or very early, reaches a height of 120–150 cm, and possesses good lodging resistance. The plant is characterized by resistance to common diseases, though it requires protection against pests.

The seeds have a dark brown color and a medium thousand kernel weight. An increased glucosinolate content allows the variety to be used for the control of nematodes and soil-borne pathogens in crop rotations.

The main purpose of the variety is the production of table mustard. It is also used as a green manure to improve soil structure, and the oilseed cake obtained after oil pressing is used for fodder purposes.
