Adjusted variety means [Eq. (1) keeping effects of genotype G _i and years Y _k fixed] plotted against first year in trial. YEAR first year in trial, GRAIN_Y grain yield at 86% dry matter, PROTIN_C crude grain protein concentration (% of dry matter), EXTRCT_C extract content in dry matter (%), FRIABLTY friability, PROTIN_S protein solution degree (Kolbach value), ATTENUTN final attenuation degree. Landmark dominating variety, certified certified by German Brewing Barley Association, registered registered for VCU. β genetic trend [Eq. (1) using Eq. (2)]. *Significant at 5% level; **significant at 1% level; ***significant at 0.1% level
