Sören's MarNar F2 Problem - RL AND PL Plants (pics)

[rnewste]

I've grown out Soren's F1 Marianna's Peace cross with Neves Azorean Red early this Summer. It was an excellent tasting variety:



I've been able to ferment seed from the F1 plants, to now start six F2 seedlings. What I am confused about is the fact that 5 of these seedlings are Regular Leaf (on the left), and 1 plant is looking more like a typical Potato Leaf plant (on the right):



Here is a closeup of the plant on the left:



This looks exactly like the leaves on all of my F1 plants.

Here is a closeup of the PL looking plant:



So, what is the "true" F2 plant that I should save seed from this Fall? I want to have F3 seed available for next Spring seedlings and I am not sure if the RL (or PL) plants are ones I should save seed from.
