Variety description

10 August 2026

Determinate type variety, the growing season is 112–115 days. The bush is compact, weakly branching, with vigorous growth, while the leaves provide protection for the fruits from sunburn. The plant does not require mandatory pruning.

The fruits have a plum-round shape, saturated red color and high density, which contributes to good transportability. The average fruit weight is 80–90 g, with the possibility of reaching 110 g. The variety is characterized by simultaneous ripening and resistance to major diseases.

The tomato is intended for cultivation in open field and film greenhouses, suitable for mechanized harvesting. The variety is of universal use: it is used fresh, for whole-fruit canning and processing into juices, paste and ketchups.
