Variety description

10 August 2026

The variety is characterized by rapid development during the initial growth period. Tubers are uniform in size, have smooth skin, and very small, shallow eyes. Culinary type B implies slight disintegration during cooking, with the tubers retaining their color after boiling.

The plant is resistant to the potato cyst nematode (pathotype Ro1) and potato wart disease. The variety has low susceptibility to common scab and internal rust spot. Foliage health is medium; protection against late blight is required.

The variety is suitable for long-term storage and packaging. It requires cultivation on high-quality soils with uniform water and nutrient supply. Pre-sprouting and careful handling during harvest are recommended to prevent mechanical damage.
