genome project for cannabis, I think that's what it is here: http://cannabisgenomics.org/

I think that trying to keep old lines pure and uncontaminated is a mistake, you can see why just by looking a dogs, chickens, what have you, if you have a Great Dane you must have spent at least $5000 in vet fees in the couple first years alone, we are weakening the gene pool by not allowing the cross breeding of cultivars/breeds. My opinion anyway...for all it's worth

People, plants, and animals all came from stable lines.
If it wasn't for those stable lines, we'd all be mutts!

You can always pull any trait out of a plant if you take time and select the trait your looking for might take years but it's possible nothing is lost more is gained. Certain traits may become less recessive but isn't that the point to only have desirable traits

People sometimes use multiple males of the same seed stock to prevent genetic bottlenecking. I think breeders today are more interested in creating unique phenotypes that could potentially become elite clones, rather than producing stable, True-breeding varieties. In the past, there wasn't as much access to clone-only's so more breeders used to work on creating true breeding varieties. Nowadays, you can just go to a club and pick up a handful of clones that people used to hoard...so there is less emphasis on trying to get clone-only's in seed form and more people I think looking to get lucky and create the next hot strain.

Multiple females is how most seed companies work once they've found a proven male that produces good offspring...just hit every elite clone in the garden with it. Gage green was using the joseph OG male for a minute and hitting everything with it.
Absolute quality post, in my eyes the OP's original post is somewhat contradictory, in that, he's suggesting selecting single plants to breed from is strengthening the gene pool??? Seems to me that's a sure fire way to cause a bottleneck in the gene pool, constant inbreeding is bad in any species.

Backyard breeders and puppy mills are the pollen chuckers of the dog world. People with no concept of how genetics work and just inbreed bad traits into pure lines so they can sell them on craigslist. They might be using pure AKC lines to breed but have zero understanding of dominant and recessive genes, they just know how to make puppies like a chucker knows how to make seed. A skilled breeder understands selection and how genes get passed and maybe even knows how to make a punnett square lol.

What are you talking about?
Have you not read any of my replies, or are you just trying to disagree just to disagree?

Yes, hybrid vigor happens when you have two stable inbred lines, and you cross those lines.
That supports what I'm saying.
Not sure what your trying to say?
I like super polyhybrids. That's not what I'm getting at.
What my complaint was that multiple males of unknown trait quality, are just mixed with a clone only.
Sure the DNA is still in the strain, but might not surface much due to recessiveness.
This only applies to breeders selling seeds to the masses. Weakening the gene pool.
Not home breeders, I encourage experimentation, and researching new techniques to further strengthen the pool.
I would like to hear more about the genome project, if you want to share.
I get what you are saying but dont quite understand how using multiple males on one female would weaken a gene pool unless these strains were getting passed around the world and infiltrating untouched wild landraces. I think people making seed with feminized stock are doing more damage.

You could hit one mother with multiple males and then BX the offspring back to the original mother and continue working towards your goal. I dont see anything wrong if someone began their process in this manner, especially if they had a stable of proven studs. It would be wrong if someone did this and decided it was ready for market after one generation.

Ok, one more time.......
Crossing a bunch of males to a clone only is not a way of making strong genetics.
Most time people aren't even sure of the genetics of the clone only, it's stability, or it's recessive traits.
They cross it and sell it, without knowing what's going to happen past the first generation.
And cultures for millennia have basically inbred their people strengthening their gene pool.
Inbreeding is to eliminate recessive traits, while reinforcing dominant traits.

I understand what your saying.
If proven males are used, sure.
But it's the selling to others that is my concern.

To assume that all pollen chuckers have zero understanding of dominant and recessive genes is quite false. A lot of pollen chuckers could do as good or better than some breeders given the space / volume.

In the end, pollen chucker or not, I do it to my taste, my favorite strains are all homemade... and came from more or less random males crossed with females that I carefully selected over the course of many years, I know how to recognize a nice female...

Also, professional breeders often go for yield and might be missing out where pollen chuckers are generally small scale growers and can select more for flavor terps over yield
