F's 1-4 are unstable almost by definition unless you get seriously lucky and get a plant that is homozygous for all traits- there's your 1 in a thousand plant.

F1 is a simple hybrid- using your Punnett squares from college genetics class *yawn* you breed Aa to a plant aa and get 25% Aa and 75% aa. See, still some variation. Or you breed 2 true-breeding lines AA x aa and get 100% Aa in the F1 generation, then take any of those and breed to each other and get 25% AA, 25% aa, and 50% Aa. So the F2 generation is really variable and not even close to stabilized.

I'm talking about lines that are truly homozygous for all traits of interest.

So yes, pure landrace strains are on the list.
Well said Stinkyattic. I was hopeing I wouldn't have to post my explaination! :thumbsup:
