UK: Early success for blight-resistant GM potato trial

Scientists inspect potato trial plotsA genetically modified potato variety designed to resist the devastating plant disease blight has successfully come through the first year of trials, say scientists. Worldwide, crop losses because of blight are estimated to be in excess of £3.5bn. However, scientists at The Sainsbury Laboratory (TSL) on the Norwich Research Park are trialling a Maris Piper potato that has been modified with blight resistance genes from a wild potato relative. “The first year of the Maris Piper trial has worked brilliantly,” said Jonathan Jones, a professor and project leader at TSL. “We’ve observed resistance to late blight in all the lines.” Prof Jones said early results suggested blight-resistant potatoes could be a way to control late blight and remove the need for multiple sprays of agrochemicals. More
