Investigating the genetics and value of root traits to support yield in barley.

• Discover QTL associated with barley root biomass, root angle, and root-to-shoot ratio, and determine whether these traits are correlated with one another.
• Determine the relationship between root traits, flowering time, and yield, and investigate the impact of root biomass on yield in different environment types.

• Root biomass is positively correlated with root : shoot ratio; root biomass is positively correlated with flowering time; root angle is negatively correlated with yield;
• Under the water-limited condition, barley crops with high root biomass & small root angle are preferred
