Variety description

10 August 2026

The variety is a spring barley possessing a strong straw, which ensures high lodging resistance. The variety was introduced in 1983 and was actively used in European breeding programs of that period.

In scientific literature, the variety is examined in the context of breeding for disease resistance, specifically to net blotch caused by the fungus Drechslera teres.
