Variety description

10 August 2026

The roots have a classic cylindrical shape with a blunt tip, a smooth surface, and a length from 15–20 to 30 cm. The flesh is distinguished by an intense orange or orange-red color, juiciness, and a sweet taste with a crunchy texture.

The variety type is mid-early, characterized by good keeping quality and suitability for universal use, including fresh consumption, culinary processing, and freezing. The plants possess relative cold tolerance, drought tolerance, and disease resistance.

Cultivation requires deep, loose, sandy or sandy-loam soils, as the roots may deform or crack if the moisture regime is disrupted or on heavy soils. Sowing in open field is carried out in the period from March to early summer.
