China Yunnan sativa pheno finishing outdoors.
Cannabinoid analysis of the sample tested at SC Labs.
I received the chinese yunnan seeds around 2002 from kernal kosmix (who unfortunatly passed away a few years later). At that time, we were in a now disappeared internet preservation forum sharing landrace genetics. I didn't pick up the seeds in person in Yunnan, kernal told me the seeds came from chinese inmigrants that were working in his area.
The seeds had a medium/small size, pale on color without (or very little) mottling. I grew them all and i found what seemed to be a landrace hash plant indica (columnar, compact, fast flowering, resinous) but with different traits to the afghani and pakistani strains i experienced before.
Around the same time i also was growing thais and other SE asian sativas, the chinese yunnan was clearly indica but had some features that reminded me northern thai/burmese strains, especially for the taste/aroma and start of the effect. It was obviously a landrace rich in THC (it was very psychoactive, not hempy kind of population). The chinese yunnan effect was at the end relaxed and meditative and i always have had the feeling that the line has some amounts of CBD too.
Thinking about the origins of cannabis, Yunnan location, ancient medical uses of chinese culture with cannabis and the mixed traits between what is classicaly consider cannabis indica traits and SE asian sativa traits, it was/is my guess that this chinese line and probably other strains from this area of the world are probably the connection between the more extreme cannabis indica strains from Afghanistan, Pakistan, North India ... and the extreme tropical sativas from SE asia. It's only my opinion, and i think the only way to know it for sure would be to make dna analysis of this unhybridized asian landraces to learn more about where the psychoactive cannabis evolved and how they genetically changed in the different geographical areas were they were spread and under the breeding pressure from different human populations.
Now the genetists have the knowledge and technology to make this kind of studies, we already know more about the origins of human populations, animals and vegetables thanks to dna studies so i think is only a matter of time that serious genetic studies about cannabis and its origin are finally done.
6 years ago i received other seeds from Yunnan province that were radically different, super big and mottled, the contact told me the yunnanese people used the seeds as a food. I grew them too, they were a hempy population with none or very little psychoactive value. China is huge and i'm sure there is a huge genetic diversity in chinese cannabis landraces.
This is the background i can share about the origins of the chinese yunnan line we have been working with since the very early days of ACE Seeds.
Sam, you are a very fortunate person to have the talent, experience and resources to explore big landrace populations and to develop excepcional strains (psychoactive or not).
Kind regards! dubi
Just to be clear was the seeds that grew the pictured plant a pure Yunnan? I ask because I have grown thousands of Yunnan and few if any had such thin leaves. That and I never found any that had 17% THC, I grew seeds collected all over Yunnan and never found one that was even 5% THC, they did have very high terpene and resin levels, some smelled exactly like Afghani plants, some smelled exactly like Thai plants, just little THC. I did not read all the earlier posts, so if this is a hybrid I understand why high THC.
BTW I did not try and raise the THC levels I was breeding for large seed size and no THC, with that I was successful, as it is quite easy to lower the THC levels in Yunnan.

hi dubi will you work the sativa side of the strain too ?
Hi dubi the last couple of weeks I've been searching all over shops for any remaining China Yunnan regular seeds and am dissapointed when I do find a e shop that has advertsed as in stock they are in reality out of stock and refund me, I read a post and you said to soeon on this thread PM me if you can't find any and I'll sort you out. I was therefore wondering if you could help me out with sourcing China Yunnan regular if you had any left many thanks.
