For further reading on the genetics of cultivated potatoes, see this:

One interesting thing it notes that pertains to the topic here, is that Solanum tuberosum 'tuberosum', which the vast majority of cultivated potatoes in North America and Europe are descended from, has short stolons vs S. tuberosum 'andigena', which has long stolons. The andigena descended potatoes, as well as S. stenotonum and S. phureja species, all have traits better suited to container growth, than tuberosum.
