CSIRO has applied to the Office of the Gene Technology Regulator to release up to 232 GM-wheat ‘‘lines’’, or plants derived from a single genetically-modified plant, and 41 barley lines from May next year. The plan will be put out for public consultation next month. [...] Earlier this month Greenpeace tried again, seeking information CSIRO held about the impacts of GM wheat, but was refused access to one document that had been classified commercial-in-confidence. Two other documents were partially released. Mr Craig said the [Office of the Gene Technology Regulator] wanted to educate the public about the benefits of GM wheat, including rust-resistant strains.
