Barley Research in TIAR
Meixue Zhou
Barley Research in TIAR Breeding
– Long season and high rainfall areas - Franklin– Spring sown barley – Vertess– Autumn sown barley - Macquarie– Part of Barley Breeding Australia - Western Note
Germplasm development– Screening and exchanging germplasm– Developing germplasm with stress tolerance
Methodology and physiological, genetic study Adding stress tolerance to Australian varieties
Barley Breeding Target
– Long season and high rainfall areas – Replacement of Gairdner
Status– Used to be an independent breeding program– Now part of Barley Breeding Australia - Western Note
Funding bodies– GRDC, TIAR
New varieties Vertess
– Only for spring sown area – replace Gairdner and Franklin– plant height - similar to Gairdner and Franklin– maturity – between Gairdner and Franklin– high yielding (6-16% higher than Gairdner)– Better tolerance to dry summer– Good malting quality– BYDV resistant– Protected by PBR– Release next year
New varieties Macquarie
– Autumn sown –replace Gairdner– plant height - short with similar to Gairdner– maturity - similar or slightly later (1-2 days) than Gairdner– Consistently high yielding (6-10% higher than Gairdner)– Average 5% higher than Gairdner in National Variety Tests (more
than 10 sites from WA, SA, VIC, NSW)– Good malting quality– BYDV resistant, better leaf rust and scald resistance than
Gairdner– Protected by PBR– Release next year
Abiotic Stress Waterlogging
– Physiological studies– Genetic and molecular marker
Acid soil (Al)– Screening method– Fine mapping– Gene cloning?
Salinity– Physiological studies– Genetic and molecular marker?
Frost Drought
Waterlogging Germplasm screening
Exchanging with China Physiological studies Molecular markers
