"Male hermies arent bad"

I can write one ina bit if you think its interesting.

yes pls, post the link after

I'm down for some twisted genetics

Despite the thread title, there's some damn good info in here, glad I stumbled on it.

If you induce flowering before the plant is mature you will get more confused/hermie plants. Most strains on the market go to alternate phylotaxy before they are mature and flowering before alternate phylo increases incidence or degree of. If you wait till they show sex you will have better stability.

The genetic expression of hermaphroditism in cannabis can be complex. When a hermaphroditic cannabis plant, whether male or female, contributes genetic material to offspring, it can increase the likelihood of producing plants with hermaphroditic traits.
If a male hermaphroditic cannabis plant pollinates a female plant, the resulting offspring might inherit genetic tendencies toward hermaphroditism. However, it's important to note that not all offspring from this cross will necessarily exhibit hermaphroditic traits, as genetic expression can vary.
The risk with using hermaphroditic plants for breeding purposes is that they might pass on genes that increase the likelihood of hermaphroditism in subsequent generations. Breeders aiming for stable, non-hermaphroditic genetics typically avoid using plants with such tendencies in their breeding programs to maintain genetic integrity and reduce the risk of hermaphroditism in their offspring.

Kind of wanted to discuss this concept I've seen theorized a few times: Maybe a "male" plant that throws a few female flowers isn't "bad". Maybe this plant tends to be sensitive to female hormones/whatever female plant signals/triggers, and isn't necessarily a plant with general intersex instability, but a plant that heavily skews towards female flowers, which would be beneficial in actual female offspring. I know the exact mechanism of both flowering and "herming" are still a bit nebulous/hotly debated


Has anyone ever tried a breeding project with "male hermies" x a normal female? It seems every breeder and chucker since the beginning of time has bred against these traits, understandably

I'm basically playing devil's advocate and trying to learn here; I don't necessarily believe this one way or the other

I had a male plant I used in a cross. I let it keep flowering outside after I was done and eventually it threw a few pistils and seeded itself. I got like 7 seeds from it somewhere. Never got around to trying it.

Never got around to trying it.

yeh I had that too and me neither ..we need to do more for “science”....

The title does directly relate to the info, though. It cites a quote directly related to the discussion/info within, thereby starting the discussion/sharing of information/sharing of opinions.

What do you mean? Are you just saying you disagree with the assertion that male hermies are bad?

Epistasis ‘sex leakiness’

Hormone and sex manipulation on cuttings, past research on hemp

So there might be different mechanisms or biochemical pathways for the resin heads? Hmmm yeah that could be why not. Don’t resin heads have their own set of cells in the head’s that can detach from the plant stalk. I am not sure about the total morphology of the resin stock or head, and I...

Can I just quickly point out that any A.I. is just a look up tool for information posted on the web, rather than an actual all knowing intelligence. So it will repeat inaccurate posts where that is what it finds. A better question would be, show peer reviewed scientific papers demonstrating the existence or non existence, of male hermaphroditic cannabis plants, excluding studies carried out on hemp. This may reveal more.

 

[Ecor1]

Interesting read, seems to make a number of good points.

That paper doesn't actually refer to cannabis at all. It includes Drosophila mainly, also talks about lizards and insects, but isn't anything to do with cannabis.

This one includes cannabis, but I'm not sure what it reveals, if anything, I'm just making a note of it here incase I lose it while reading. Often my phone will go and what I'm looking at disappears.

Ah it seems to show that in the active Y lines, only females show male flowers at times, whereas in the X to autosome lines (which to clarify come from the east Asian areas like Laos Cambodia Thailand etc) the "males" in the line will show female flowers.




Table 2. Sexual lability in 22 species with well-described sex chromosomes. The lability types correspond to those summarized in table 1. Am, andromonoecious; Gm, gynomonoecious; M, monoecious; Tm, trimonoecious; H, monoclinous. For species with reported leakiness, the leaky sex is indicated in parenthesis: f, female; m, male; b, both sexes. For clarity, species without reported lability are indicated with a dash in all columns. This table also includes references to the literature on sex chromosomes. For details, see electronic supplementary material, table S1.
