Variety description

10 August 2026

The variety was obtained as a result of breeding work using the parent lines Flamingsnova, Swan mut., and Dukat. The variety is included in the history of the Polish national register and was actively used in the past as a reference object in grain quality research, including the analysis of thousand kernel weight.

In regional trials, the variety was mentioned in the context of cultivation in mountainous conditions. Detailed morphological characteristics, such as plant height or disease resistance scores, are absent in current publications as the variety has been withdrawn from active circulation.
