Pan-European research identified up to 10 blight-resistant varieties. The Blight-Mop project results were detailed by Newcastle University professor Carlo Liefert at the Soil Association’s annual conference.
He said: “The project has ensured organic potatoes will be more widely available and of an equal, if not better, quality and closer to the price of potatoes grown using chemicals.”
Soil Association director Patrick Holden said: “Organic potato growing can be technically challenging. We hope these varieties will enable farmers to produce more.”
