Dr Greg Rebetzke

Research Geneticist

Contact details:

GPO BOX 1700


Dr Greg Rebetzke, Chief Research Scientist at CSIRO Agriculture and Food, contributes to the understanding of genetic and physiological factors affecting water productivity and adapting to changing climates in rainfed winter cereals. His goal is then to deliver elite trait-containing germplasm, and improved phenotyping and genetic methods for trait enrichment in commercial breeding programs. Greg contributes to a number of grower and scientific advisory committees. He serves as an editorial advisor on key international journals while serving as an editor on the Journal of Experimental Botany. Greg also supervises in the training of students and postdoctoral researchers. As a leader in CSIRO Agriculture and Food, Greg works closely with Australian commercial breeding programs to deliver improved crop performance in new varieties released to farmers. His research has delivered to new commercial wheat varieties and breeding methodologies used in Australia and overseas. He links strongly with regional agronomists to identify opportunities and facilitate delivery in farming systems relevant to current and future climates, and in reducing the cost and risk of grain production while increasing grower profitability and sustainability.
