Variety description

10 August 2026

The variety belongs to the early-maturing group. The development feature consists of the stem growth stopping with the onset of flowering, which allows nutrients to be redirected to the tubers. The variety is suitable for annual use, while irrigation contributes to an increase in the average weight of the tubers.

The produce is distinguished by a high content of mono- and disaccharides, while the maximum level of inulin in the stems is reached by the end of July. In field experiments, the level of latent tuber infection by phytopathogenic fungi was recorded at up to 5%.

The main direction of use for the variety is energy crop production, in particular the extraction of bioethanol and biogas due to the intensity of carbohydrate accumulation.
