The proposed project will develop standard protocols and methods for the identification of crop genotypes with root characteristics contributing to efficient phosphorus acquisition from low fertility soils. Root traits to be considered include root architecture, root hair length and density, specific root length, root cortical aerenchyma, and production of phosphorus mobilizing root exudates. Each of these traits has distinct screening protocols.
