Potato (Solanum tuberosum L.) late blight, caused by Phytophthora infestans (Mont.) de Bary, is one of the most damaging diseases in any crop. Deployment of resistant varieties is the most effective way to control this disease. However, breeding for late blight resistance has been a challenge because the race-specific resistance genes introgressed from wild potato S. demissum Lindl. have been short lived and breeding for "horizontal" or durable resistance has achieved only moderate successes. We previously demonstrated that the high-level late blight resistance in a wild potato relative, S. ...
