Variety description

10 August 2026

The variety belongs to the Hyvido winter barley hybrid line. It possesses vigorous autumn development, which makes it suitable for direct drilling and high-weed-pressure conditions, and is also distinguished by a rapid maturation rate, facilitating high-quality threshing.

The plant possesses a balanced resistance profile to leaf blotch (Rhynchosporium), ramularia, brown rust, powdery mildew, and lodging. The variety is specifically adapted for areas infested with BaYMV-1 and BaYMV-2 type barley yellow mosaic viruses.

The variety's produce is characterized by a high thousand kernel weight. The hybrid is intended for intensive cultivation technologies and for growing on difficult sites that require the crop's ability to compensate for external conditions.
