Variety description

10 August 2026

The variety is mid-season; the period from emergence to leaf lodging is 90–115 days. The plant reaches a height of 40–50 cm.

The bulbs have a round or obovate shape and are covered with dense straw-yellow or greenish-yellow scales. The flesh is white, juicy, and has a semi-sharp taste. The neck is thin, which ensures rapid drying.

The variety is distinguished by a high dry matter content, bulb uniformity, and good storage life, reaching 7–8 months. It is suitable for cultivation as an annual crop or from sets and is intended for universal use.
