i heard of a 6 weeker Chinese finding once in a flowertime test of multiple southern chineese lines…

You’re saying wild weed is highly bottlenecked? Or did you mean CBD bud?
Could it be Korean? I’m wondering. Some GI goes on R and R and comes back with seed?
It could have thc. I bet it does. Some plants look feral, others have a Dalat look to them. N vietnam has pole pheno thc plants, too. Could be something like that got nailed with N viet hemp pollen…
Someone found an 11% thc plant in Hokkaido Hemp. This could be another completely genetically unique hemp strain, too. The N Vietnamese hybridized their short hemp with tall hemp recently.
I don’t know if they even have a pure version of the short hemp anymore. It was used to make very fine clothing. The fiber is softer than other hemp.
Could be Chinese too. I’m hoping at least some plants keep flowering another month. Then we’ll know this is something subtropical…
European hemp.
here a study in wich Cannabis Strains Autoflower genes emerge.
a very interesting exerpt: (as tip: LD means long daylenght / SD short Daylenght, )
Recently, Chen et al., (2022) collected both natural and domesticated accession of
360 cannabis across China. Flowering time experiments showed that wild collections flowered under
361 LD. All natural accessions except for two, were collected in northern China at latitudes ranging
362 from 41.50 – 50.16°N. The two which were not from northern China were collected in northern
363 Yunnan and Xizang province, close to the Tibetan plateau where cannabis is proposed to have
364 originated (McPartland et al., 2019). Gene expression analysis of florigen CsHd3a showed strong
365 upregulation under LD in wild accessions, similar to our observations in Figure 3a. Furthermore,
366 an analysis of nucleotide diversity between domesticated photoperiod sensitive and wild
367 accessions identified genes under positive selection, of which CsPRR37 was significant. Like rice,
368 natural variation in CsPRR37 may be involved in cannabis adaptation to varying latitudes by
369 regulating flowering time, with loss-of-function alleles present in the highest latitude regions. A
370 detailed analysis of CsPRR37 in wild and domesticate genotypes adapted to varying latitudes will
371 be required to confirm this hypothesis. Currently, sequence data from auto-flowering wild
372 accession collected by Chen et al., (2022) are under embargo, however, wild accession collected
373 by Ren et al., (2021) overlap geographical regions. While flowering time was not analyzed in this
374 study, the search for CsPRR37 mutation(s) within these accessions is underway.
so, in other words: in yunnans wild species they found upregulation of this flowering-impulse, or whatever it is…
this matches with a small study of a couple chinese cultivars where it was mentioned that a couple wild yunnan species flowerd in 30 Days, wich is unbelevable fast…
Becuase hte small study was sritten in this scientifical style i believed it. Even its hard… Given that yunnan has mediterran climate and is around 25 degree north.
This is very fast flowering for its latitude and temperatures…

I have a zamal (from Bama seeds) that germinated in January -
started flowering under 18/6 lighting in late July
not an auto-flower per-say - probably just a mature sativa ; ready to go !

i love your bama seeds man ust lately you showed that Morrocan wich is quiet pretty looking, never even heard of them Bama seeds.
would you show a zamal pic please, and well, did it flower trough till finish?

They also seem to say something like: this fastflowering Tendency seems to emerge when a genetic comes from different climates background. (various climates)
That would explain why @Upstate finds hybrids of two landraces to flower 2 weeks faster then the landraces…
hmm, you were totally correct.

thanks for the pic!
The Zamal loos genetically quiet cool.
Im astonished there is such few interesse in the Study i linked , i mean the study says they try to find Autoflower/ or short Floewring tendencies in otherwise Photoperiodic Populations…Wich is a good thing.
In my oppinon thats a very interesting study, alltho i couldnt understand the most wordings, lol.
Like said : two things seem to correlate with above average fast flowering (above average for its region) , 1) Wild Genes 2) Anchestry from varying Regions (i dont mean one of multiple Anchestry beeing from north, i mean simply varying regions, diverse terroirs).
Said that, its astonishing that two regions of where we know we found semiauto traits in tropics ARE VOLCANIC REGIONS… Namely Madagascar (zamal) and Papua newguinea. Remeber that PNG from the OG Giveaway?
Yes, bouth have very high density of Vulcanos… My thinking is that vulcanic soils are so different than any normal soil, that it acts as “varying terroirs” … !!
If so, then we should search semi-auto traits where there are Vulcanos, and where they grew the Strains quiet wild, without constant selection… (im pretty certain wildness is the case for PNG).
Also it can give us furter Confidence that per example zamal eventually isnt just a ruderalis anchestry… but is that holy grail semiauto tropical flower…

Also, i understood it that the varying Regions Thingy is because Cannabis does start to loosen the Floweringtime-Gene a bit, in other words: when multiple Regions are in the Anchestry, the cannbis Genome detects that it needs to adjust the flowering-gene (like evolution/adaption). And in this moment (or this Generations) that it loosens / or varys the floweringtime-gene , some individuals lean thowards incredible short flowering … Some thowards longflowering… simply variation…
So, and those varying climates dont need to be very Cold/ VS a little less Cold Climate…
It simply needs to be varying…
That could also be Ultra hot Climate / Vs warm Climate… Or like said some very crazy Soilchanges may probably also play into it, as we know prunning Roots per example can cause Flowering… Thats because the Roots do aswell detect and adjust Flowering-time… I know that from researching the Flowering-gene called Florigen wich is present in Leaves but also the roots…
Just like all plants - flower time can be “triggered” with 13 -13.5 hrs of dark time. Remember reading this - any biology (plant) guy’s please chime in —Thanks !! Really a plant does have a built in flower time so to say - so light is your variable
remember my goal is to flower a pure sativa faster /or even during summer.
i am past lecture 1 in cannabis, haha (i dont mean it bad) thanks

if you want to have a faster harvest time consider dark times: examples of
for sativa’s:
veg at 12/12 for 3 weeks
24-48hr DARK time before flower flip
flower at 13hrs dark 11hrs light
consider putting you plant in a dark place for 24hr.s ( have use this before and seem to shorten flower time by 1 week) FYI

Perhaps it is the soil itself. Volcanic soil is loaded with so many good things, perhaps one of those good things is in short supply in the soil used in a Western grow and the plant responds by auto flowering??? Unlikely…but…

Here is the Snippet about Variation…
Photoperiod insensitivity is a common trait observed in SD crops domesticated in higher
350 latitudes. Intensive artificial selection in rice has allowed its adaptation to latitudes as high as
351 53°N. Rice grown at these latitudes flower extremely early with weak or no photoperiod
352 sensitivity (Wei et al., 2008; Fujino and Sekiguchi 2005). Crosses between late flowering indica
353 cultivars with early flowering japonica have identified many distinct heading date QTLs
354 contributing to a diverse range of flowering times . A major effect QTL Hd2 was identified as OsPRR37 (Murakami et al. 2005; Koo et al., 2013). Koo et al. (2013) showed that natural variation in OsPRR37 contributed
357 to the expansion of rice cultivation in northern latitudes, where cultivars grown at the most
358 northern regions contained loss-of-function alleles.
Yeah ok , they used Indica and Sativa… So it may have not to do with “variation” but just with the Indica Gene coming trough.
But im uncertain… i heard about the word Variation already once when they spoke about Bambo adaption to higher altitudes…
did the zamal finish already?
