Screening for genetic components of head retention in barley (UAD3223)

Barley head loss is an ongoing issue that leads to reduced yield based on environmental factors and cultivar sensitivity. Although management options exist, improved genetic solutions are needed to limit the seasonal and site variability. In this project, researchers will extend current knowledge of head loss management and peduncle structure to consider new cultivars and candidate genes that might influence head retention.

Manipulating spike architecture to improve wheat yield (UAD3123)

This project will be undertaken by SARDI researchers who will use a novel bread wheat mapping population and high-throughput phenotyping method (X-ray computed tomography) to measure spike traits that contribute to yield, and identify genetic markers associated with improved yield for breeding programs. This project includes controlled environment studies and field trials.

Developing new breeding material to stabilise barley yields (UAD2023)

South Australian crops can be severely impacted by poor and variable growing conditions, which includes low-fertility soils. Crop plants possess strong instincts to reduce grain number due to variable growing conditions or reduced fertiliser. This is a major contributor to the yield gap in SA. This project seeks to help close this yield gap through the import and testing of new genetic material that makes barley less responsive to environmental conditions.
