Greg Rebetzke

Dr. Greg Rebetzke is Chief Research Scientist at CSIRO Agriculture and Food, focusing on genetic and physiological factors affecting water productivity in rainfed winter cereals and adaptation to changing climates. He delivers elite trait-containing germplasm and improved phenotyping and genetic methods for commercial breeding programs.

• Contributions to grower and scientific advisory committees
• Editorial roles on Journal of Experimental Botany and other international journals
• Leadership in projects like frost susceptibility in wheat and long coleoptile wheats adoption

His research integrates genotype x systems approaches for early growth establishment in canola and wheat, statistical and quantitative genetics, and phenomics in breeding. Key themes include climate adaptation, GxExM synergies, and sustainable grain production.

Scientific accolades include:

• 2023 University of Queensland Distinguished Past Student Award
• 2023 Grains Industry 'Seed of Light' Award
• 2021-2023 Grains Industry 'Research Excellence' Award
• 2014 Australian Academy of Science Travel Award
• 2009-2011 CSIRO Newton-Turner Senior Researcher Award

Over 25 years at CSIRO, he has supervised students/postdocs and collaborated with Australian commercial breeding programs to release new wheat varieties. His work addresses frost resistance, deep sowing adaptation, and reducing production costs while enhancing profitability.
