GREEN grain is a large LINK project sponsored by Defra and SEERAD in collaboration with HGCA, Syngenta, Scottish Crop Research Institute, Scotch Whisky Research Institute, Wessex Grain, Grampian Country Foods Group, FOSS UK Ltd and Nottingham University. The project has the combined aims of genetically reducing the nitrogen emissions and growing costs of wheat production whilst enhancing the value of wheat grain for the bioethanol and grain distilling industries, for pigs and poultry and for other markets. The project seeks to achieve these goals by identifying wheat genotypes with minimal nitrogen storage in the stems, and reduced gliadin protein in the grain.
