Variety description

10 August 2026

The variety was obtained by crossing the Red Globe and Princess varieties. It belongs to the category of table grapes intended for commercial cultivation. The berries have a neutral-sweet taste and belong to the first class of seedlessness, containing only barely noticeable seed rudiments.

The bunches have a cylindro-conical shape and medium density. The vigor of the vines is rated as medium. The variety is characterized by high fertility, which requires crop regulation and short pruning of the vines. During storage, the produce maintains its quality for 6 weeks.

The variety matures in the late season, significantly later than the Flame Seedless and Crimson Seedless varieties. At low temperatures, uneven bud burst may occur. No specific data on resistance to major fungal diseases and winter hardiness are presented in open sources.
