Increasing attention is paid to providing tools to breeders to underpin targeted breeding for specific root traits that may be useful in low-fertility, drying soils; however, such information is not available for barley (Hordeum vulgare L.). We phenotyped 191 barley accessions from Australia for 26 root and shoot traits using the established semi-hydroponic system, and identified significant variation (CV >=0.25) for 16 of the traits evaluated. The population structure and marker-trait association (MTA) were assessed using 21,061 high-quality genotyping-by-sequencing (GBS)-based single nucleotide polymorphism (SNP) markers. The population structure analysis of the barley panel identified six distinct groups. A total of 435 significant (P
