Certified seed potatoes are tested for diseases, and that is the main reason to used them, as far as I know. Here in Alaska, we have been relatively free of potato blight, etc, so the Cooperative Extension highly recommends buying certified seed potatoes rather than using sprouting potatoes from the grocery that may come from out of state.

A common problem with potatoes in our area, due to the excess rainfall, I imagine, is scabbing. I grow my potatoes in barrels, and if they have scab, I not only don't use any of those potatoes as seed potatoes, but I do not use the same soil for potatoes the next year. If your potatoes are healthy, using offspring for seed potatoes should be fine.
