Genetics for 2021!

no (or little) viable seed.

Eg see: Triploid and seedless genetics high CBD genetics

Or bananas

you know, the whole one copy from mom, one copy from dad thing…

only mom’ s got 3 sets of chromosomes, and no mater how those are lined up at the plate, nothing ever (seldom) seems to get pulled apart correctly.

…and if by “triploid” you’re still referring to your phyllotactic variant; “stealth” was one reason ABC was allowed to live.

I am going to be running a bunch of my “Eskimo Breath” crosses ( jelly breath X Eskimo pie ) and
“Kimbosa” ( Kimbo kush X Mimosa ) … plenty of pics on my Instagram @island.genetics

This again…

Have you seen this as a phenotypic expression as a result of stress induction? Curious because I’ve only seen it on healthy seedlings without stress. I don’t doubt it may happen, nature is crazy :upside_down_face:. Just wondering if you have seen it.

Triploid doesn’t grow differently than diploid when created by skilled growers. It doesn’t produce “multiple main colas” as rule. It’s just sterile.

Ask GW pharmaceuticals and Hortapharm B.V., LOL. The latter (owned/operated by David Wastron - aka Sam Skunman - along with David Potter), produces/used to produce only triploid seeds they called “clones,” which they sold to GW Pharma. HortaPharm did this as a way to control their stock and prevent breeding with them. GW used to buy all their “clones” from HortaPharm, because under the contract GW wasn’t allowed to keep mothers for propagation. Pretty sure GW bought out HortaPharm some time after that, considering David Potter now works for GW. At least that was the basic story last time I heard it…

The Aussies at it again, lol.

Stress no. But it’s relatively easy to induce this change in colius with a scalpel.

That’s what I was referring to from asking about inducing stress. Have you done this? Specifically in cannabis?

Stress can mean all sorts of things other than physical injury (cell ablation if you want Google fodder).

A bigger meristem will give more space for primordia, and is likely the cause in @Cheebachiefextracts case.

I see little to no point in repeating 50year old exploration of the physical constraints in cannabis. Because they won’t pass through the seed. But it would probably make a great platform for teaching the concept (Colius is easier to acquire).

I had Ian Sussex and Sarah Hake on my thesis committee. Ian did a lot of meristem ablation, Sarah’s lab did a lot of molecular mapping of gene expression as related to branch primordia. See links provided…

I wasn’t entirely thinking for seed production mostly just clone/snip stock plant, if that may be worth while?

Was a seedling with large meristem & one of the faster ones that had popped. If I recall right I had to do a little surgery( don’t think I scraped it, but I remember it being twisted a little on this one into the towel.

If it’s actually a “mutant” that codes for a larger meristem, then maybe. Otherwise the phene will be lost in the axillary (branch) meristems, so it won’t clone either.

So as soon as that meristem is cut even to top it the plant can loose the gene in further nodes?

Yup, I’m very familiar with this in Coleus. I used the term stress because we’re on a forum and I’m not trying to be pedantic. I was just wondering if you have done it with cannabis, or you know someone who has, because you seemed to imply that’s the reason it occurs in cannabis (vs mutation). I’ve seen it countless times in large seed runs, along with a quad version.

It seems to be common in some lines, like what @Cheebachiefextracts mentioned with the Mac crosses. Which seems to imply genotypic not phenotypic.

Many people have grown out these types of plants, and I have yet to know anyone who was glad they did. If you’re short on space in your garden, I’d just cull it now. But for science, experiment away! :slight_smile:

If I had cannabis data I’d share it. Or at least mention I had it.

Thanks for the spell check on Coleus :rofl:

Does not imply “not a mutant”.

It states that there are other possibilities. If you’re seeing multiples of the same phene from seed, then chances are there IS a genetic change that is changing the way the meristem is set up.

Given the error rate on replication, it’s also possible that almost every time you see it, it’s genetic. I was just pointing out that that particular phene (altered phylotaxi) is one that doesn’t require dna level changes a priori.

Same page?!?

Idk haven’t really been following lmao. If he’s lying then yea he’s a scumbag scammer. He might think he has a legit cut, etc etc. Possibilities are endless.

Yes sir, :100:%

I agree with everything you wrote. Communication on the Interwebs is interesting, missing that human inflection with a person-to-person dialog.

Your thesis committee is impressive. I have read research co-authored by Sarah Hake in the past. And after I looked at the Scholar search for Ian Sussex, I realized I had read a few of his co-authored papers as well. That is quite the pedigree you have! If you don’t mind me asking, what was the topic of your thesis?

I’m gonna see if she stays for science. Let her pan out a little & see if I like the structure or not & if it’ll keep the trait.

RIP deshazzo. Sucks was gonna drop a few mints on stuff.

Anyone else have anything fun?
