Solanum verrucosum
Solanum verrucosum is a species of wild potato in the family Solanaceae, native to Mexico. It is typically found in cloud forests at above sea level. Its tubers are small and late to develop, but said to be quite tasty. A diploid, it is being extensively studied for its resistance to "Phytophthora infestans" (the cause of late potato blight), and Potato leafroll virus, in an effort to improve the domestic potato "Solanum tuberosum".
