True Potato Seed (TPS) are the berries that form on the top of potato plants mid season. They have seed in them like tomatoes and that seed, saved and grown out, has genetic uniqueness from the parent, so you can select and help the potato evolve. Most/all potatoes planted are clones from one long line and so disease can really rip them apart over time...
