To examine 10 wheat cultivars sown on 20 May for yield and quality assessments under a two-spray fungicide management (foliar application– GS31 and GS39) .
• The feed winter wheat cultivars RGT Cesario and Big Red sown on 20 May over three weeks later than the earlier sowing trial (FAR VIC W22-02-1 reported above) were significantly higher yielding than the shorter season spring milling wheats Willaura, Rockstar and Scepter.
• The new white wheat Stockade (AWW with APW potential) performed strongly outyielding older feed wheats Anapurna and RGT Accroc which were both significantly lower yielding.
• Despite a two-spray fungicide package and later sowing reducing disease pressure there was considerable disease infection present, particularly Septoria tritici blotch and stripe rust in Scepter and Rockstar.
• Incomplete disease control with these two milling wheats led to poor grain quality characteristics (test weight in particular) and a 3-4t/ha deficit compared to best European origin feed wheats.
