Brief description The crop root systems are poorly suited to harsh conditions in Australian agriculture, especially as climate is getting drier. Poor water-use efficiency lowers crop yields below the potential yield; moreover, unutilised water and nutrients contribute to environmental problems, eg salinity and eutrophication. This project will use our simulation model to develop computer-aided design of 3-D root structure and function (water and nutrient uptake) tailored to particular environments. Modelling will also link suitable root traits to genetic markers in well-characterised lupin germplasm. The blueprint developed here will be adaptable to other crops. The project will enhance breeding for increased water- and nutrient-use efficiency.
