Variety description

10 August 2026

The hybrid was created during many years of research on the development of a genetic system for producing hybrids, where the influence of radish was used to prevent self-pollination. According to its classification, the variety belonged to hybrid-line composite variants.

At the time of registration, the variety possessed a high level of yield, demonstrating an indicator of 123% relative to the control values of that period. It was developed to increase production efficiency and develop the hybrid seed market, however, it is currently a historical variety and is not used in modern agricultural production.
