Eyespot - Variety Tolerance in Commercial Varieties locations
Aims

To explore variety tolerance of eyespot in commercial varieties.

Key messages

Findings are from one site in one season and more data will be needed before firm recommendations can be made.
• Where eyespot inoculum is present in paddocks at medium to high levels, avoid sowing Wedgetail and Orion. Trojan, Manning, and DS Pascal would be better choices, as would Compass if sowing a barley.
• Experience across 6 screening trials undertaken in SA in 2014 and 2015 indicates that some varieties (e.g. Trojan, Compass) are very consistent in their response to eyespot, but others (e.g.Hindmarsh, La Trobe, Corack, Shield) are not.
• Cereal types and varieties with weak straw are more likely to be at risk of lodging (and harvest difficulties) in the presence of eyespot than those which have good straw strength. Plant growth regulants might assist in reducing lodging issues.
• The range of susceptibilities shown within the varieties screened should provide a good base for breeding programs.
