Dr. Delphine Fleury completed her PhD in 2001 at the ENSAT (Toulouse, France) and her postdoctoral training in 2005 at the Department of Plant Systems Biology (VIB, Ghent, Belgium). Dr.
Fleury joined the Australian Centre for Plant Functional Genomics in Adelaide (Australia) in 2006. She runs the genetics program aiming to improve the tolerance of wheat and barley to drought
using quantitative genetics, physiology and omics. Her group par- ticularly focused on the positional cloning of quantitative trait loci increasing yield under low rain-fed environment. She is also co-in- vestigator with the ARC Industrial Transformation Hub linked to Australian breeding companies on genetics diversity and molecu- lar breeding for wheat in a hot and dry climate.
In Australian dryland agriculture, grain crop yields are approx- imately 50% of their potential and are highly unpredictable.
During the 1990’s, the rate of productivity increase in Austral- ian broad acre cropping improved by 3.4% annually but has since slowed and declined by -1.4% in drought years. A way to improve the drought tolerance of crops varieties is to discov- er new genes and alleles that allow plants to continue to grow and yield grain under water limited conditions. Although many quantitative trait loci (QTL) have been identified in wheat, few have been deployed in breeding programmes.
We cumulated QTL over 10 years on three wheat populations for yield, agronomical, physiological and morphological traits in various locations in Australia, India and Mexico. Genomic resources now enable us make progress in fine mapping and
