Barley Research in TIAR Meixue Zhou

Barley Research in TIAR s Breeding –Long season and high rainfall areas - Franklin –Spring sown barley – Vertess –Autumn sown barley - Macquarie –Part of Barley Breeding Australia - Western Note s Germplasm development –Screening and exchanging germplasm –Developing germplasm with stress tolerance u Methodology and physiological, genetic study u Adding stress tolerance to Australian varieties

Barley Breeding s Target –Long season and high rainfall areas –Replacement of Gairdner s Status –Used to be an independent breeding program –Now part of Barley Breeding Australia - Western Note s Funding bodies –GRDC, TIAR

New varieties s 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 s 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 s Waterlogging –Physiological studies –Genetic and molecular marker s Acid soil (Al) –Screening method –Fine mapping –Gene cloning? s Salinity –Physiological studies –Genetic and molecular marker? s Frost s Drought
