Adapting wheat to arid environments: mining Canadian germplasm for reduced night-time water loss and improved water productivtiy
Crop Types
- Wheat
Collaborating Locations
AAFC SaskatoonBackground
Wheat continues to lose water even during night-time when temperatures drop. In the absence of photosynthesis during darkness, this portion of the wasteful water loss could be reduced by selecting for low night-time transpiration The knowledge, germplasm and markers generated from this project will accelerate breeding cycles and benefit the wheat industry.
Objectives
- Quantify the range of night-time transpiration water loss in a collection of wheat accessions
- Identify stomatal strategies that allow wheat to thrive and maintain high yield under arid environments
- Assess the role of epicuticular waxes and individual components on water loss.
- Identify the underlying genetic basis of contrasting wheat lines with varying night-time water losses by gene expression studies
- Showcase the most promising lines for improved productivity under arid environments through field days
