This !as i said above, im not a breeder , but i've given human genetics exams in college, and i dont get what you call uniformity, because the only way to have uniformity is homozygosis which in turn means you've got a super reduced genetic pool hence you're talking about IBL. If you believe you can have uniformity and a big gene pool you're plain wrong. you can have kindah uniform ( still not uniform) offsprings by crossing homozygous plants, but still, the gene pool is super reduced and unless you're into genetic engineering using CRISPR/CAS9, reducing the genepool too much is not a great idea since you are carrying with you shitty genes together with what you're selecting in most cases, just take a look at commercial fruit plants, they are so shitty that you must graft them on semi-wild or genetically modified rootstocks . I dont want that with cannabis, do you?
Funny I cant find a single pic of anything you have done.Ahh I'm just trying to copy you oh great one
Uniformity and IBL are two different things !
You don't need IBL to have uniform plants.
No, because when you take P1 and cross it to the offspring or self it, that's IBL, but it's not uniform.
Two different things again, you don't need to dwell in the line you hold in order to stabilize it, you can cross it to other genetics and work from there, it won't be IBL but you can reach uniform results either way.
IBLs are just genetics that had been worked on only in that genetic pool direction, no outcrossing.
That's it, if the breeder knows what he is doing, that IBL will be uniform but in today's market you see BX1 and BX2 that are all over the place, meaning they don't reach uniformity.
Yes, IBL is inbreeding, meaning you only breed with itself or offspring, no outcross.
The definition is accurate but people do not follow it through as P1 with sister is IBL too but it's only the 1st gen so very far from true breed or stability.
IBL usually lose vigor but hybridizing restores it. You can have plants that look the same but you may lose other traits ex: potency. In dogs for instance, you may get the breed standard for looks but lose some of the temperament or gait or whatever.Still gotta be only 1 pheno expression from a sibling mating...sticking to my guns on that...maybe alleles are only 87%...but if it spits out only 1 pheno ...you have an IBL
That's why we include fems and autosDEI club for cannabis...woke weed...that weed doesn't have enough diversity
98.6 per cent for all traits haha and who has seen such a line in cannabis? Esp without any selfing? Better looking into isogenic lines well NIL ones.Ibl is defined as:
Relatively homozygous line produced by
inbreeding and selection.
Another source states:
A nearly homozygous line obtained through continuous inbreeding of a cross pollinated species with selection accompanying inbreeding.
"Relatively" "nearly".. ive seen 98.6% homozygous given as a standard minimum.
Quantitative traits are usually easy to fix, seed shape and color, structure, flower color and shape, autos, cannabinoid ratio and the like.
Those imo should be close to 100%, no excuse.
Qualitative traits are polygenic and can be a pita to fix, quality of high, yield and friends. Still.. transgressive segregant traits are inheritable.
Ibl title based on number of filial generation can kick rocks.
