Breeding G-13 Clones for Seeds.

I am wondering how many times I can breed offspring back to the parent. I know G-13 only exists in clone form, but I want to create seeds. I thought of line breeding dogs and concluded the same theory should work for cannabis. I want to find a worthy indica strain to breed to the G-13. From the 50/50 G-13 seeds I want to find a vigorous male to breed back to the G-13 to produce a 75/25 G-13 cross, and again for an 87.5/12.5 G-13 cross. How many times can I do this? Eventually, I would end up with a seed 99.9% G-13, but would/could there be genetic or otherwise defects from the breeding? Is there a limit to the number of times offspring can be bred back to the parent? Please help! I'll share the seeds.:weed:

Interesting idea...I too am growing a G13 cross right now (G13xBuddha) I know I've heard people say not to cross back too many times, but the only real risk is that you might unwittingly strengthen weaker genes during the process. I would think that eventually you could get a seed bearing plant that greatly reflects G13 genetics.

G13 x Buddah is right along the lines of what you are trying to accomplish with the 75/25 thing. (The one I have is anyway.) Why wouldn't you just purchase those seeds and then work from there if it wasn't quite what you wanted? Would be a lot easier. I've been breeding forever and things don't always work out the way you hope. Starting with G13 x Buddah might be a good idea in your case, obviously I don't really know. Just trying to help.

EDIT: Hmmm ... after re-reading your post I may be in error. I always think in terms of Sativa/Indica for some reason, meaning 75/25 Buddah in this case ... now I think you might have meant 75% G13? If so, sorry. :-)

Your talking about "cubing" a strain, the science is a little complicated but the process is pretty simple, look it up. After about 3 generations your seeds will 99% of the time resemble your original g-13 mother. Just do a simple searching on cubing a strain. And make sure you choose your father very selectively or you will find that you will never get exactly what your looking for from those seeds. Good luck

I found this...."This is how it works it simple terms. You have a clone only female cannabis plant youd like to have seeds of. These seeds will produce plants that display 50% of the females traits and 50% of the males. You pollinate her with a male plant keeping a copy or clone of the original mother alive. This is an outcross and these seeds are grown out and the best male is selected based on desired traits. This male is then used to again pollinate the original mother plant. The seeds of this breeding will produce seeds that display 75% attributes of the mother plant. This process is continued twice more until the strain is cubed and in theory 99% of what the mother was." A simple description of cubing by Subcool

While I do agree with that for the most part, it must be pointed out that the statement will only hold true if the desired genes are in fact the strongest genes. When you start crossing strains you must be aware that alot, ALOT of factors will ultimately decide what genes shine through. For example if you were to cross G13 with a heat tolerant strain in a hot growroom which genes would be passed along? The heat tolerance will more than likely be present in the next generation.

Ideally that 'cubing' would work just great, but you would really have to know your strains exact characteristics to know whether or not it's working. Not that it couldn't be done, I just wouldn't rely on the math over nature...plants adapt to environmental changes, you'd have to have ideal everything to rely on the numbers to work for you IMO.

Well said..your exactly right. That could lead to a long(and fun) discussion. I like the point you made about knowing the strains your workin with. That is very important and taken for granted by many. Add that with the proper environment and you have a solid foundation for a project, other wise you wont really know what you really have. Your example of a hot room was on point. You may have very well passed on the genes you desired but the phenotype being expressed doesnt display that because of the unfavorable conditions of the environment. Well said hubert:peace:

yea you can unwittingly strengthen weaker genes, but that is largely eliminated by proper/selective breeding..not that I claim to be an expert, as I have yet to create anything worthy of much lol

Hey, sorry to interject. I was just curious about the strain itself, does it get good yields, give a good high, etc?

thanx for the info. maybe G-13 x Buddah is the strain I should cross with. I see there is much to consider, and a lot of trial and error to be experienced. here, hit this: :joint:
