Variety description

10 August 2026

The variety has a primocane type of fruiting, in which berries are formed on first-year canes. The plant has an upright growth habit and exceptionally high development vigor. It is characterized as semi-thornless: thorns are present only in the lower part of the canes up to a height of about 90 cm; the fruiting zone remains thornless.

The berries are large, weighing 7–8 g, with a glossy surface, excellent firmness, and a balanced flavor. The variety demonstrates resistance to sunburn and fruit development defects, such as white drupelet disorder. The productivity of the variety is comparable to the best floricane varieties.
