Component pattern for principal components 1 and 2 for genetic correlations of grain yield and components, grain traits, and malting traits (dashed ellipsis). Unity circle (100%) indicates that variation of traits is explained fully and the smaller circle (50%) that only half is explained by principle components 1 and 2, respectively. GRAIN_Y grain yield at 86% dry matter, EAR_D single ear density, KERNLS_E number of kernels per ear, TGM thousand grain mass at 86% dry matter, GRAIN2.5 grain fraction with kernel size >2.5 mm, HECTOL_W hectoliter weight (test weight), PROTIN_C crude grain protein concentration (% of dry matter), EXTRCT_C extract content in dry matter (%), MALTNG_L malting loss, FRIABLTY friability, VISCOSTY viscosity, PROTIN_S protein solution degree (Kolbach value), ATTENUTN final attenuation degree
