Variety description

10 August 2026

The variety belongs to the Marais de l'Ouest type, which determines its ability to adapt to specific soil waterlogging conditions, especially in the autumn period. Studies note its high resistance to the alfalfa crown wart pathogen Urophlyctis.

Morphologically, the variety demonstrates the formation of significant biomass and a large number of stems. Despite its productivity, individual genotypes of the variety show a relatively low protein concentration in the green mass. The variety also shows good seed productivity indicators under favorable development parameters of racemes on the shoots.
