This is going to be a long list guys.
Also there is no reason to put stablized hybrid after them. Because almost everyone listed is a hybrid.
I think you may be thinking of Landrace strains. Not IBL's.
I might be mistaken.
But IBL's can be either a landrace strain or a hybrid.
If it's bred selectivly for several generations then it's the begining of an IBL.
After that it just gets more and more stable.
Like each seed is close to a clone.
But to bring it to that point.
You would have to breed hundreds of plants to find that one female to continue the line with.
Same with the males.
But you need to grow 100-200 females to find the best one.
Especially in the F1,F2 and F3 stage.
Because if you don't use the right mothers nd fathers. Your gene pool gets pigeon holed after several backcrosses.
So if you aren't pigeon holing the best possible parts of that gene pool then you are going to end up with a very stable OK strain.
But nothing very special.
I mean you could accidentally find something or get lucky.
But for the most part.
I think you might be thinking of IBL's as Landraces.
Not sure though.
Just trying to clear things up.
I mean almost ever strain belongs on this list.
Especially from seedbanks.
Unless it says it's an F1 or F2 then it's an IBL.
Even an F2 can be an IBL. If someone decides it to be.
See what I mean.
