Variety description

10 August 2026

The variety belongs to the group of long-fruited greenhouse cucumbers of the European type. In scientific literature, its traits are described as benchmarks for this segment, and the variety itself is often used as a control object when studying plant resistance to powdery mildew and downy mildew.

The fruits of this hybrid are smooth and dark green. Due to the fact that the variety is a representative of previous breeding generations, it has been displaced by modern hybrids possessing higher yield indicators and resistance to current strains of viruses and fungal diseases.
