This paper presents results from the Cudal site (southern NSW) and discusses the influence of sowing date on the phenology and grain yield responses of a core set of 30 wheat genotypes.
• Frost had a significant effect on phenology and grain yield responses in 2017.
• High grain yields were achieved through a range of sowing date × variety combinations, indicating
that growers can optimise yield through various sowing options.
• Differences in pre-flowering development phases were observed among genotypes of similar
maturity, resulting in a significant influence on grain yield responses in 2017.
