Im growing Sour Bubble from seed. its a bubblegum backcrossed. Does this mean it came from a female bubblegum and a male bubblegum?

what does back crossing actually mean?

Backcrossing is when they breed back to one of the original strains.
I just read this online:
B.O.G. Seeds - Sour Bubble
A very unusual bubblegum derived from my BOGBubble gene pool. This is my most potent strain.
SourBubble promises to be my best Medical Strain to date. Flowers in 49 - 55 days.
Its all bogbubble but each backcross male was chosen from the offspring of the previous generation
and now the 3rd bx males have pollenated the clone mother once again to cube the sour bubble with
the 4th bx. But that isnt the end of the work. From there we still have some way to go.

Back crossing is mating the offspring back to the original parent of the first generation as opposed to line breeding which would be mating siblings from each successive generation!
If you want to put it crudely it's like fucking your mother!
Let's say you find some great smoke in bag seed. You have made a cutting out of your plant and you breed it with a male from the same population. But the offspring from that Resultant second generation do not have the desirable traits that were present in the mother. So instead of continuing with line breeding you pollinate the original cutting again, with its' own offspring.

Back crossing is often used when there is a desirable cut acquired but there is no male from the same population to pollinate it. So you would cross it with a proven male and select a male from the offspring to backross to the original. The problems arise when the original cut is not itself stable and can't produce stable offspring. selfing is more often used nowadays as a better tool for stabilizing desirable genetics. Back crossing also leads to inbreeding depression very quickly.
Sweeth Tooth #3 is a famous back cross.
There will be threads on this subject, the best discussions will be with Tom Hill and Chimaera.

^ all good. the problem is that for proper backcrossing one needs to do proper selection in choosing an offspring that heavily favors the parent that you are bx'ing back into. in a fresh, unstabalized hybrid (called f1) the f1 offspring may all be 'tweeners between mom and dad. in that case you make seeds from the first batch of seeds f1's. this second successive line of seeds is called f2's. the f2's are going to have a lot more variation ( more than the original seeds f1's).
you take the f1's (choose seedlings that are as close to mom as you can ) and make seeds again (f2's).
you then take an f2 seedling that heavily favors mom and use that to back cross into mom.
so, mom's killer. no family, no relatives. you use a stud to knock her up. the kids look like a cross between mom and dad ( no phenotype separation). these kids are f1's. mom and dad are the two different p1's; p for parent, f for filial generation. f1 is first filial generation, f2 is 2nd filial generation, etc..
you need one of mom's kids (f) that is like mom to cross back into mom for a proper bx where the resultant seeds resemble mom when grown out. just crossing any of mom's kids back into mom is not a proper bx. to get a seedling that favors one parent (mom) you often need to make f2's for what they call phenotype separation. in f2's you can expect 1): 'tweeners, 2):"takes after mom", 3):"takes after dad". you need to use a f2 that "takes after mom" for the proper bx back into mom.
^ this is why a lot of bx's are so shitty. they did not take the time/trouble to make f2's to get the phenotype separation necessary to get a good seedling for the bx.

Preach it idiit...
That's spot on how I would go about making a bc(bx)... every time!
A back cross using F1 offspring seems somewhat useless since phenotype variation will be minimal. F2s are the platinum generation for selection for nearly any breeding program (that's properly planned).

Are there still breeders who prefer back crossing when selfing is an option?
^dubi at ace seeds does not self yet ( recent comment from him, some day he may).
I don't think ppl nowadays ( the market) trust bx's too much. if a breeder used a bx to get the desired results he might not fully disclose.
the selfing especially in a strain with homogeneous traits would quickly lead to loss of vigor and possible other inbreeding symptoms like lack of hardiness, etc. a good bx maintains genetic strength and the s1 keeps a good mom for the future bx's. if you only got one mom ( no relatives) using both s1's and bx's together to maintain the line in seed form seems logical.

So we can say it is an inferior breeding tool to selfing/reverse pollination?
find a plant ya like, make seeds with it , take males of those seeds and breed it back to the mom, these seeds are bx1 , take males from these bx1 seeds and dust the mom, these seeds are bx2 and should have loads of phenos like the mom, ya can take those males and make bx3 , ive seen all the way to bx4 and then they seemed to really be stunted and fucked geneticaly maybe losing vigor , good luck, i make seeds everytime i grow , its addicting , have fun
Backcrossing is a cross between an offspring generation to a parental generation.
Here's the sticky part. When you self (reverse) cannabis, the males disappear.
If that plant is heterozygous for the desired trait (or homozygous for that matter) yet has other wanted characteristics then backcrossing (linebreeding) may be the way to go.
With selfing, a plant that is heterozygous for a desired trait (dominant), the offspring will show the trait in 3 of 4 individuals. This shows the plant is heterozygous for the trait. If the plant is homozygous for the trait all will show it. (This does not necessarily apply to quantitative traits).

wanting to keep it simple here on this thread so I think we did pretty good for the answer.
