Variety description

10 August 2026

The variety belongs to the relatively early group, although in a number of trials it demonstrated a longer growing period compared to other samples. The plant forms quite broad leaves and a stem with a small number of thickenings.

The level of product uniformity is assessed as medium, and leaf coloration is satisfactory. The variety shows susceptibility to rust and leaf spot, and is also sensitive to mechanical damage and bolting.
