Variety description

10 August 2026

The hybrid is a diploid monogerm form of the three-way top cross hybrid type. Its genetic and biological characteristics have made the variety a standard subject in scientific research on biotechnology, including experiments on agrobacterial transformation to study mechanisms of resistance to pathogens.

In terms of phytopathology, the hybrid shows resistance to Cercospora leaf spot, but possesses susceptibility to the rhizomania virus. Information on agronomic performance, such as yield or sugar content in specific units, is not presented in publications as independent data.
