Means for vegetative growth, anthesis biomass, and water-soluble stem carbohydrates (WSC) measured on 16 near-isogenic pairs varying for the presence and absence of awns, and representing four genetically-contrasting wheat backgrounds in droughted and irrigated (in parenthesis) environments in the Managed Environments Facilities (at Merredin, Narrabri and Yanco in 2012–13)
