10 August 2026

The variety forms a short and dense stem. It possesses intermediate resistance (IR) to Puccinia allii (leek rust), as well as to Ap, Psp, and Tt. It shows natural resistance to rust (yellow rust).

Due to very high resistance to bolting, the variety is suitable for early planting and is capable of showing high efficiency in challenging growing conditions. Possesses high yield potential.
