yeah i agree to sell it as a specific strain you have to do the x then if you dont bx and stabilize then you cant really sell a strain you x 1 time with other stiff n say when it pops it will come out like the picture they have posted. thats just uncool and they would do better to let us know as some of us would buy those seeds in the crap shoot. but yeah if you are honest about it n say i got the original from this dude n its this x with that. but some dude was trashing me cuz i said that because he wouldnt give me a few training day beans n if i didnt have the cash i couldnt get them before they sell out n its a limited line id just do my own breed n cross the LA con from DNA seeds and a trainwreak of my choosing. if i can find my camera ill take a picture of a example of a plant that doesnt look the best but has a effect worth saving....
I personally do not believe back crossing is the way to make a strain. It is definitely a tool in the breeding arsenal, but I do not believe that is the way to finalize a hybrid strain.
Back-crossing would be better suited to stabilizing a line.
Example:
Find your parent lines. Lets say a landrace called LR and the other is HB.
First you want to stabilize LR.
Grow out your LR seeds cross them and select into the next generation (many ways to do this step).
LR2 might give some nice plants so you choose a few of the best.
LR3 is starting to look more like you want, again select and cross.
Keep going until things are really looking like you want.
IF you find a plant you REAALLLY like, this is where you might backcross.
You should be stabilizing LR to your liking, and doing the same process to your HB line.
At this point LR and HB are completely separate.
Once the seeds start coming out the way you want, you find your parent plant (by the way of progeny testing).
Cross your final LR parent to your final HB parent.
This is a good hybrid.
The counter to this is crossing the best LR from your original seed to your best HB from original seed. Then backcrossing that cross to one of the parents. This is NOT a good hybrid, it is an excuse.
