With growers` increased focus on dual-purpose (DP) cereal varieties and the development of new DP varieties, a set of experiments investigating the grazing and grain recovery of DP cereals were run at Wagga Wagga in 2016 and 2017. The experiments were designed in a randomised complete block with one or two factors. With two factors e.g. variety and sowing time, the experiments were arranged in split-plot or factorial (depending on the second factor). Sixty three different wheat, barley and triticale genotypes were tested over the two years, with a core subset of 24 genotypes studied in detail. Various measurements and plant traits such as plant population, plant growth stage, dry matter production, morphological attributes, grain yield and quality were recorded. The study found that there were differences between both crop type and genotypes and how they accumulated dry matter and then recovered from grazing to produce grain. The key variables and traits were plant population, tillers number and leaf dry weight for dry matter production before anthesis and total dry matter, fertile tiller number and stem dry weight at anthesis for grain yield.
