UK: GM potato trial showing positive signs of blight resistance at Sainsbury Laboratory

The Sainsbury Laboratory is trialling a genetically-modified potato designed to be resistant to blight.

Picture: The Sainsbury Laboratory.A genetically-modified (GM) potato designed to resist late blight has worked “brilliantly” during the first year of field trials, according to Norwich scientists. The field trial conducted by The Sainsbury Laboratory (TSL) on the Norwich Research Park involves incorporating three blight-resistant genes from a wild potato relative into the popular commercial variety Maris Piper. After the first year of the field trial, scientists observed a marked improvement in late blight resistance, with a stark difference in health between the resistant and non-resistant plants. Prof Jonathan Jones, who is leading the project, said the initial results offered hope that there could be a way of controlling late blight without the need for chemical fungicide sprays.
