Variety description

10 August 2026

The variety was bred as a result of crossing the Primura and KO 51-0123 varieties. The plant is tall, semi-erect, with white flowers. The tubers are large, oval or round-oval in shape with smooth light yellow skin and eyes of medium depth. The vegetation period is 65–75 days.

The starch content varies from 10 to 19.2%. The variety is resistant to potato wart, a number of viruses (Yntn, Yn, X, A), and potato nematode, however, it shows susceptibility to common scab. Susceptibility to late blight is noted in the leaves with relative resistance of the tubers.
