Brenton Leske: Providing an overview of the project
Australian wheat and barley frost susceptibility benchmarking research
Preliminary yield data has shown some wheat varieties are able to compensate for loss in grain number, due to frost damage, by increasing grain size and weight. Identifying varieties that have a greater ability to compensate for yield loss could provide an avenue for growers to reduce financial losses due to frost in susceptible areas. As well as FS, viable and non-viable tillers will be assessed from over 30 commercial varieties of wheat.
The project is a collaborative effort between DPIRD, Kalyx, Living Farm and University of Adelaide, with trial sites in Western Australia, South Australia and New South Wales.
This project commenced in 2014 and will run for five years until June 2019. The project builds on the work currently being done under the Screening and Benchmarking project which uses phenotyping methods based on frost induced sterility at flowering.
