Smoke report!

I love Chocolope and I am trying to find a solid landrace Thai.

Did you see the article about how the guy in the 70s miss-identified the three families of cannabis? By using DNA they were able to determine the origins of the three as:
  • What we call Sativa now really came from India and should be called Indica
  • What we call Indica now really came from Afghanistan and should be called Afghanica.
  • What we call Ruderalis now really came from Asia and should be called Sativa.
This wont make things confusing!


Cheers,
Mo

I saw that thread and it makes sense... but fuck is that gonna rustle some feathers and confuse the piss out of everyone's grandma. I'd like to see a "professional study" that states or clarifies the origin of the original land races that's led us to what we're growing today.

The three species idea was put forth by Richard E. Schultes...in the 1960's...Robert C. Clarke and Vavilov [who proposed 4 sp.] are at least two others, who have reported on or have differing theories since Schultes. There are more, just what I have off the top of my head...

I don't want to thread hijack...I actually have a copy of Schultes and several others, some from the International Journal of Hemp....

but....

"The debate on whether there is more than one species has been intense, for the issue has legal implications."

I should blog about it.

Sample populations of 157 Cannabis accessions of diverse geographic origin were surveyed for allozyme variation at 17 gene loci. The frequencies of 52 alleles were subjected to principal components analysis. A scatter plot revealed two major groups of accessions. The sativa gene pool includes fiber/seed landraces from Europe, Asia Minor, and Central Asia, and ruderal populations from Eastern Europe. The indica gene pool includes fiber/seed landraces from eastern Asia, narrow-leafleted drug strains from southern Asia, Africa, and Latin America, wide-leafleted drug strains from Afghanistan and Pakistan, and feral populations from India and Nepal. A third putative gene pool includes ruderal populations from Central Asia. None of the previous taxonomic concepts that were tested adequately circumscribe the sativa and indica gene pools. A polytypic concept of Cannabis is proposed, which recognizes three species, C. sativa, C. indica and C. ruderalis, and seven putative taxa.

Cannabinoids are important chemotaxonomic markers unique to Cannabis. Previous studies show that a plant's dry-weight ratio of Δ9-tetrahydrocannabinol (THC) to cannabidiol (CBD) can be assigned to one of three chemotypes and that alleles BD and BT encode alloenzymes that catalyze the conversion of cannabigerol to CBD and THC, respectively. In the present study, the frequencies of BD and BT in sample populations of 157 Cannabis accessions were determined from CBD and THC banding patterns, visualized by starch gel electrophoresis. Gas chromatography was used to quantify cannabinoid levels in 96 of the same accessions. The data were interpreted with respect to previous analyses of genetic and morphological variation in the same germplasm collection. Two biotypes (infraspecific taxa of unassigned rank) of C. sativa and four biotypes of C. indica were recognized. Mean THC levels and the frequency of BT were significantly higher in C. indica than C. sativa. The proportion of high THC/CBD chemotype plants in most accessions assigned to C. sativa was <25% and in most accessions assigned to C. indica was >25%. Plants with relatively high levels of tetrahydrocannabivarin (THCV) and/or cannabidivarin (CBDV) were common only in C. indica. This study supports a two-species concept of Cannabis.

The "genome" is getting more value than the final product ...
They are getting close ,to what they wanted to achieve,firstplace with mj plant.
Now ,with full control over the plant genes ,they can slowly prepare a world-scale decriminalisation ...
Or put in other words ...
"Open new markets " ...
Simple.
Money talks ,BS walks ...

Just remember what I state today 19/02/2015 ...
In few decades ,it would be way difficult to find seeds .
All of us we will be obligated to buy seeds ,in order to grow ...

-Yes ,what about the wild landstrains ,then ?

They won't be any seed producing wild landstrains ,by then ....
Already a massive gene "pollution" has begun some years ago ...
You 're all aware of "organisations" like i.e. " greenhouse sseds " and their "strain hunters " ....
Are you really aware what exactly they are doing ,travelling all over the world ?
You do not need a biology degree ,to understand what's going on ,really ...

Cheers.

Richard Schultes, The Botany and Chemistry of Cannabis
Obviously, neither Vavilov nor Zhukovskii envisage genetically stable "varietates" in these concepts, since both indicate that the main argument in their decisions concerning the origion of cultivated hemp is that this plant, even to-day, especially in central Asia, can be found in a truly wild state. Zhukovskii further supports his decisions with the belief that the species Cannabis ruderalis and the C. indica cannot be ancestral types of the cultivated C. sativa....Mansfeld recognizes still different categories: Cannabis indica in India [especially NW India] Iran and eastern Afghanistan; and C. sativa with two sub-species: wild or cultivated subspecies, spontanea [ or C. ruderalis] of Altai, Tienshan, Transcaucasia, Afghanistan, the Balkans and middle Europe; and C.culta, indigenous to Asia [N. Himalayas and Hindu-Kush to China] Europe, North Africa, North and South American, Australia.

Since that doesn't really work, I attached the whole PDF.....

Shao Hong1 and Robert C. Clarke2

History and literature Contemporary Chinese Cannabis studies began in the 1950's, soon after the People's Republic of China was founded. During those days, a general natural resources survey was carried out all over China. The medicinal and economic values of Cannabis were first recorded in Flora of Chinese Medicinal Plants (Pei and Chou 1951) and it is also recorded in the Chinese Pharmacopoeia of 1957. Chinese scientists early noticed that Cannabis is a widely distributed plant in China and has medical and other productive applications. Two of the first Chinese books on plant taxonomy, Pictorial Handbook of Chinese Plants (Chia et al. 1958) and Dictionary of Families and Genera of Chinese Seed Plants (How 1958), simultaneously named Cannabis from China as C. sativa L. Since this name was also recorded in Iconographia Cormophytorum Sinicorum (ASBI 1972), one of the most comprehensive and highly respected Chinese plant taxonomy reference books, C. sativa L. has been regarded as the representative name for Chinese Cannabis.
Another form name, C. sativa L. f. ruderalis (Janisch.) Chu, was recorded in Flora Plantarum Herbacearum Chine Boreali-Orientalis (Chu 1959). This new form name was also adopted by Flora of Chinese Economic Plants (Anon. 1961) and specifically represented the Cannabis distributed in some areas of northeastern China. The specimens representing this form in Chinese herbaria do not exhibit the key anatomical character described by Janischevsky (1924), i.e., that the fruit base becomes elongated and forms a "caruncle". However, his collections from Altai and Yili in Xinjiang Province possess the so-called "caruncle" only in some fruits from the same plant. The lack of a caruncle may result from incomplete maturation. Based on the lack of consistent expression of this primary discriminating character, both the form name and the original species name are questionable.
Zhao (1991) proposed that there are four varieties of C. sativa L. distributed in China; sativa, spontanea, indica and kafiristanica. However, while only presenting a basic classification key derived from Small and Cronquist (1976), she did not provide Chinese representative voucher specimens or delimit the range of these taxa except that the specimens from Fukang, Xinjiang, was identified as spontanea.
The Morphology Department of the Botanical Institute of the Academia Sinica (ASBI 1960) reported on the pollen surface features of Chinese Cannabis in Pollen Morphologies of Chinese Plants. The ASBI Handbook of Chinese Oil Plants (1973) discusses the constituents of Cannabis seed oil. Other important chemical components of Cannabis such as the cannabinoids, and the terpenoids which account for its unique aromas, are listed in Lexicon of Chinese Traditional Medicinal Plants (Jiangsu New Medical College 1975), Compilation of Chinese Herbal Medicines (Anon. 1978) and Flora of Economic Plants in Shandong Province (Anon. 1978). Other papers scattered in various journals report the cannabinoid content of specimens from several provinces (e.g. Ling et al. 1985, Liu et al. 1992, Chen et al. 1993, Zhan et al. 1994).
Large scale comprehensive scientific research on Cannabis from 1986 through 1990 (encompassing the disciplines of chemistry, anatomy, morphology, pharmacognosy, drug use survey, etc.) was carried out in several institutes in a coordinated program organized by the National Institute for the Control of Pharmaceutical and Biological Products under the organization of the Bureau of Public Health. The results are collected mostly in Corpus of Scientific Theses on Cannabis (Anonymous 1991).
