Tetraploid and triploid seeds

Djonkoman isn't around anymore either.
I've given this my best guess, I can't argue about this, as it's just guesswork. I can't say more than I have already.

Ur probably right about the haploid diploid stuff...im thinking ur idea of deliverying the genetic material is maybe not worded in a way i expect to hear it

I'm not 100% it's a triploid.. ive always called a plant with an extra leaf and flower site a triploid.. I'm not to informed on the scientific stuff about them... i know the basic information... View attachment 19022481 View attachment 19022482
Yeah tetraploid diploid is talking about the amount of chromosomes. They are created with a chemical called colchicine.

Three or more shoots from the same node is called a whorl.

"When triploid plants try to reproduce with other triploid plants, their offspring will end up with an odd number of chromosomes (3n + 3n = 6n), which is usually not viable for the plant to survive. This results in no viable seeds being produced. Additionally, triploid plants often have difficulties in meiosis, the process of cell division required for sexual reproduction, which further hinders seed production"

In theory, a triploid male would produce two types of pollen a) diploid (two DNA samples) and b) haploid (one DNA sample (the normal way)).
A female triploid would do the same with their pollen receptor sites (ovums).
The diploid pollen maybe too large for the female haploid sites, but would pollinate the diploid receptor sites. The haploid pollen would pollinate the haploid receptor sites, and would produce normal diploid seeds. The haploid pollen may, but probably not in most cases, pollinate a few diploid receptor sites, creating more triploid seeds, but greatly reduced in number. The diploid pollen may pollinate the diploid receptors, if the haploid pollen didn't get there first, and create tetraploid seeds.
So in the reduced seed sets, I would hazard a guess, that you would end up with a mix of normal seeds, triploids, and tetraploids.
But that's all guess work and should not be considered gospel.
Wish djonkoman was still around.
Only way to know is to do it. Then test any seeds produced. But people in that position are more likely to produce papers and patent applications that post their results here.

I'll never spend money on this sterile bullshit.

Hey, want germplasm you can't reproduce?
(...)
People don't want to admit that the profit motive makes shit worse for everyone.
With all due respect to the OG growers, it seems like a speech that could have made sense in the 80s, not in 2024: the profit you're talking about in the canna-business ($) today comes mainly from the sale of elite clones flowers and from the sale of autoflowering seeds, two forms of business independent of the fertility of the strains.

In this scenario, it seems to me that being scandalized by some sterile seeds is a bit anachronistic.

I guess I'm not hoping to replicate acclimation . Rather mimic a natural process known to be positive in the wild. Especially for plants with multiple cannabinoid synthases , diverse genotypes or open up lines that are powerful but have had genetic bottlenecks or silenced genes . Like take haze a male. The closest cultivars to pure a are relegated to 4 or 5 f1s salvaged over 30 years. If we take those f1s double em up and tgen open pollinated in one room and do pedigree 1 to 1in other. Playing with these progeny could pull some ancestor throwbacks without outcrossing. It's a niche to start but you can stop the process when your satisfied and use results as clone only or a harvest volunteer for tissue culture. This line bandaid haze ix3.0 breeding strategy reinforces A ancestors and also appears to throw polyploid/aneuploid action. Last study on thc synthase I read found 4 thc synthaae in a haze clone. The Vietnam dalat/viet black also has some funky faciated inflorences roo.
So, couple things here; first, I'm not educated much on ploidy, so I won't wade into that discussion much if at all, except to say all testing to date has shown no benefit in real terms.

On your pics here, a lot of people confuse Whorled Phylotaxy with polyploid states, which is wrong. The first two pics are just crested fasciation, I've had several like that over the years. They outgrow it, and more often than not it's caused by an infection spread by insects. Thrips in many cases. The third pic is Whorled Phylotaxy, not "triploid" as a lot of people confuse. You could call it a "Tricot", but probably not "triploid". Not sure about the fourth pic, need more angles. That last pic is just a Bandaid Haze ix from Doc D... I've found lots of mutants in his A5 x Mirakel Thai crosses.

If you folks don't mind, what would be the label for this lady. Zoom in on the stem and I think you'll see it. Front right.

I can't tell for certain from the one pic, but looks like crested fasciation. Would need a shot of the main stem near the top to be sure.

Yeah. Flat stem/crested (they usually go together) fasciation. It can be genetic, or can be caused by a bacterial or viral infection passed on by pests.
