Quantifying the potential yield benefit of root traits in a target population of environments
Keywords: root, drought, water deficit, wheat, APSIM model, genotype-environment interaction
AbstractDespite their importance, roots characteristics and their influence on crop growth remain poorly understood. A modelling approach was used to evaluate the potential impact of different root traits in targeted environments. Increased root extractable water at depth gave some substantial advantage to crops in all regions of the Australian wheatbelt, while increased root growth rate was only advantageous in the West of the belt.
