Variety description

10 August 2026

The plant has a semi-erect habit, reaching low to medium height, and blooms with white flowers. Tubers are characterized by an oval shape, white or yellowish skin, and white flesh with shallow to medium-depth eyes.

The variety possesses high resistance to potato virus A and tobacco rattle virus, field immunity to potato wart, but exhibits low to medium resistance to common scab and high susceptibility to late blight of foliage and tubers.

The culinary type of the potato varies from floury to firm. In a number of countries, the variety was withdrawn from markets due to total glycoalkaloid content exceeding permissible safety limits.
