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.

Developing new breeding material to stabilise barley yields (UAD2023)
Nov 23, 2023 | Current Projects
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.
Higher barley yield through improved microbial interactions (UAD1823)
Nov 23, 2023 | Current Projects
The aims of this project are to determine whether Australian barley varieties differ in their effects on the diversity of potentially beneficial soil microbes in the field, and to investigate the genetic control of any observed differences. This will result in growers being able to choose varieties that will benefit soil biological health and provide new molecular tools for breeders to use in selection to develop new varieties with improved soil biological health.
Genetic and fungicidal control of Septoria tritici blotch and stripe rust in wheat (AGX4223)
Nov 22, 2023 | Current Projects
This project will seek to evaluate the effectiveness of various fungicide treatments for control of Septoria tritici blotch and stripe rust in a range of wheat varieties with differing levels of resistance at different rainfall zones. It will also determine the genetic influence of yield loss from disease and find a suitable application package of fungicide to reduce the cost of production.
