Abstract

Crop resilience is imperative to ensure food security in the face of increasing temperatures and reducing rainfall in many regions. Under late season drought, crops with a stay-green phenotype can remain green for longer after flowering. More roots at depth can contribute by increasing late, deep soil moisture uptake. High-throughput phenotyping methods were developed and used to study a specifically designed genetic mapping population which was also phenotyped in 22 field environments. Lines with adaptive stay-green and root traits were identified then provided to commercial Australian wheat breeders along with molecular markers to accelerate genetic progress toward improved crop resilience.

With over 30 years in plant science research, Jack has focussed on improving crop resilience in the face of environmental stresses including, adaptation to frost, water-limitation, heat stress and optimising root architecture, particularly in wheat and barley.

After completing his PhD at the University of Adelaide, Jack moved to northern Australia to study plant adaptation to water stress at James Cook University, Townsville. In 2002 Jack joined the wheat improvement program at the Department of Agriculture and Fisheries Queensland at the Leslie Research Facility in Toowoomba, joining QAAFI as a founding research fellow in 2010.
