It sounds reasonable to me, Marie. As the presenter says, seed potatoes begin as clones with the intent to determine that they are disease free. Tubers are grown from that plant tissue. Tubers – also clones.
The gardener would have to be especially careful with an outdoor location while growing just from shoots.
A second crop of potatoes? I tried that once with a variety of early potatoes that I could harvest in July. Moving to a different bed, I replanted some. Only a few showed up as green plants before frost. The next Spring, a few more showed up. I suspect that those that grew in late Summer died over Winter. The ones growing in the New Year were from those tubers that didn't grow the first year.
I had asked a local potato farmer about it before I tried it. He said that he didn't think that it would work. He was right. Perhaps, a second crop would have been successful in a more southern, more climate friendly location.
