Variety description

10 August 2026

The variety belongs to the "00" type with low erucic acid and glucosinolate content. The main value of the plant lies in the presence of resistance genes to the pathogen Plasmodiophora brassicae, derived from European rutabaga.

Agronomically, the variety possesses a significant yield reduction compared to productive hybrids, which caused it to be displaced from widespread commercial use. The variety's resistance is not absolute and is ineffective against certain highly virulent isolates of the pathogen.
