Waite Ag, Food, Wine Seminar Series
Nov 14, 10:30 am
Please come along to this campus-wide seminar series. One week we will hear from a group leader or a visitor to the campus and the following week from ECR/MCRs from the Waite Future Leaders cohort. Come and hear about great science going on across the campus, up the road or across the sea! Expand your network and find new collaborators!
Everyone is welcome to a shared morning tea (please bring your own coffee cup) following the seminar.
WHEN: Thursday 14th November. 10:30am Seminar, followed by morning tea
WHERE: Plant Research Centre Auditorium
Dr Rhiannon Schilling, Postdoctoral Fellow – School of Ag, Food & Wine
The challenges of sodic soils
Soils with alkaline sodic (dispersive) subsoils are widespread in the Australian grains belt. Improving the tolerance of wheat to the range of stresses encountered in these soils has the potential to improve yield and water use efficiency. Wheat varieties were tested at sites on alkaline soils with varying degrees of sodicity in all mainland States. The lines were also screened for tolerance to high boron, high pH, waterlogging at germination and aluminium. Genetic correlations among sites from the southern and western regions were high but were markedly different from the Queensland sites. The benefit of tolerance to multiple stresses was expressed at sodic sites with yields less than about 3 t/ha and tolerance to soil constraints was estimated to improve yields by up to 10% when yields were less than 2 t/ha.
