Variety description

10 August 2026

The variety is classified as a table potato and is frequently mentioned in scientific literature as a donor of resistance to viral diseases. Resistance to Potato virus Y is provided by the Ny-1 gene, which induces a hypersensitive response that limits the spread of the virus at temperatures around 20 °C.

The effectiveness of the variety's defense mechanism may decrease when temperatures rise to 28 °C, which increases the risk of systemic infection. The variety has undergone scientific trials for yield stability and starch content as part of breeding research aimed at adaptation to the climatic conditions of Poland.
