IBL/ Truly stabilized strains

[stinkyattic]

I'd like to get a list going of strains that have been stabilized for many years and are known to breed true.

There are always people around who want to keep generating their own seeds, without understanding that the strains they are working with may be F1s, heterozygotes, unstable, etc.

So here's my list of suspects to start, please correct me if I'm mistaken, and PLEASE PLEASE add to the list!

Skunk#1
Northern Lights#1
Island Sweet Skunk
Big Bud (original)

Thanks all!

you need to take NL's off that list, its never been stable and has never bred true. I'll need to look over my research, theres really not many, as most that claim that it is an IBL strain either don't know the meaning of IBL or are just flat out lying. But you already have the others that I know off the top of my head, Skunk #1 and Big Bud. Nice thread though, I support your decision to compile a list. Though I don't think it will be very long, lol.

yea but IBLs can be stable with lost of back crossings and even so be alot more potent the reg uncrossed strains

[stinkyattic]

It's weird, I do keep finding references to NL#1 being an IBL. Hm, I tend to believe you though Smoky.

Here's some more I found, poking around:
Original Haze=IBL
Afghan#1=IBL
Durban Pison=IBL
Malawi Gold=IBL
Power Plant=IBL (not PPP)
Skunk Passion=IBL
Master Kush=Stabilized hybrid
Original Blueberry=Stabilized hybrid

Additions/subtractions?

[smoky mcpot 05]

Well I can tell you for a fact that its not, I'm glad that your with me. Also what the hell is Durban Pison? lol, just kidding not splitting hairs...Pretty sure that Hash Plant is an IBL, not sure if Master Kush is stable, know for a fact that DJshorts Blueberry is though.

Hindu Kush - IBL
Eary California - Stable Hybrid relatively true breeding
Early Girl - Stable Hybrid also relatively true breeding.
Swahili - IBL
Mistique - IBL
Island Sweet Skunk - Stable Hybrid not IBL, original creator Federation Seeds.
thats all that I got for now.

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.

Yes, what definition are you using to define your list IBL's ?

Nope.

In Bred Line.. totally different from hybrid. Eventually you can stabilize the hybrid by backcrossing, but you're unlikely to get to the true-breeding point for several generations.

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:
