Dr Greg Rebetzke: breeding wheat
Dr Greg Rebetzke is part of a CSIRO Plant Industry team involved in physiological and molecular wheat breeding.
16 December 2008 | Updated 4 June 2012
Dr Greg Rebetzke uses modern statistical and genetic methods in germplasm development to improve wheat productivity under drought.
Dr Rebetzke works in the Physiological and Molecular Wheat Breeding sub-program which includes a team of physiologists, geneticists and breeders identifying and selecting traits that are important in improving wheat adaptation to Australian environments.
The wheat breeding program is targeting greater transpiration efficiency.
The nature and timing of water limitation varies across Australia.
This provides a particular challenge to the breeder.
Improved performance under drought through greater water-use efficiency enables a targeted approach to breeding for different regions.
The wheat breeding program is targeting greater transpiration efficiency by selecting for:
carbon isotope discrimination
improved establishment through use of alternative dwarfing genes
greater early vigour for reducing soil evaporation and competition with weeds.
Genetic gain is being achieved through phenotypic and molecular marker-assisted selection.
Dr Rebetzke has been awarded a:
- Bachelor of Applied Science in Horticulture with Honours from Queensland Agricultural University, Brisbane, Queensland, Australia
- Master of Agricultural Science, from the University of Queensland, Brisbane
- Doctor of Philosophy from North Carolina State University, USA.
