What the material used to propagate Irish potatoes?

Irish potatoes are vegetatively propagated using seed potatoes. Seed potatoes are small, whole potatoes selected from healthy, disease-free plants. These potatoes are specially certified to ensure they are free from common potato diseases such as late blight, blackleg, and ring rot. Seed potatoes are typically planted in the spring, and they produce new plants that grow into mature potato plants. The new plants form tubers, which are the edible potatoes that we harvest and consume.
