Australian Cereal Rust Control Program - Wheat and barley breeding support

Abstract

This collection includes results of rust screening of advanced breeding lines of bread wheat, barley, and oats with identified rust pathotypes in the greenhouse and in field between 2018 and 2022. Greenhouse rust testing was conducted at the USYD plant breeding institute in Camden, while in field rust testing took place in three sites; two in Camden, NSW (“Lansdowne” and “Horse Unit”) and one in Karalee, QLD. Cereal breeders submitted material to be screened for disease response, rust pathotypes used in both greenhouse and field testing were chosen with the objective of identifying industry-wide resistant cultivars.

A Fee for Service (FFS) program was subsidised by GRDC for barley and oat testing. These datasets with raw scores are stored on the USYD-RDS at \\shared.sydney.edu.au\research-data\PRJ-ACRCP_prebreeding. All wheat rust data including raw and interpreted scores can be found on the NVT website https://nvt.grdc.com.au/.

Please contact Prof. Robert Park (robert.park@sydney.edu.au) or Dr. Laura Ziems (laura.ziems@sydney.edu.au) if you require access to any of the following: a) Contingency tables with the frequencies of tests per crop per year, b) Summary table showing the presence/absence of pathotypes in seven main pathogens per year, c) Datasets with the raw rust scores for oats and barley Cereal breeders submitted material to be screened with the most important rust pathotypes; those used in both greenhouse and field testing were chosen for relevance in reaching the objective of industry-wide resistant cultivars.
