Professor Richard Trethowan
I want to produce more food with less water: I am interested in developing crop cultivars that use water more efficiently. We can introduce genetic variation for stress tolerance into commercial cultivars from ancestral forms of some of the world’s most important food crops. This work benefits the agriculture industry in many ways: it increases productivity, raises income, and improves the sustainability of farming systems.
A combined genetic and agronomic approach to improving productivity – while maintaining the resource base – is vital in the context of climate change.
Richard was appointed as a Professor of Plant Breeding in the Faculty in 2006. He has a B.Sc and a PhD from the University of Sydney, and is currently Director of the IA Watson Grain Research Centre within the Plant Breeding Institute. He leads the Crop and Food Systems research group within the Faculty of Agriculture and Environment and is the Product Delivery Coordinator for Wheat In Asia for the Generation Challenge Program. Prior to 2006 he led the Wheat Breeding Program for Rainfed Areas at the International Maize and Wheat Improvement Centre, headquartered near Mexico City.
