Background: Sweet potato (Ipomoea batatas (L.) Lam.), a key global root crop, faces challenges due to its narrow genetic background. This issue can be addressed by utilizing the diverse genetic resources of sweet potato’s wild relatives, which are invaluable for its genetic improvement. Methods: The morphological differences in leaves, stems, and r...
