According to the definition in the encyclopedia of plant genetic resources, a landrace is an early, cultivated form of a crop species, evolved from a wild population, and generally composed of a heterogeneous mixture of genotypes. Therefore a cannabis landrace is a marijuana plant species that has been geographically isolated from the possibility of cross-breeding with any other strain of a similar plant species. If we were discussing vegetables or another type of plant we'd be using the term "heirloom".
For many years some of the leading Cannabis Seed Company owners have taken a keen interest in preserving the great original marijuana strains of the world and several even work together, creating Seed Banks. There are some important reasons that landrace cannabis has become popular, first because they're the best strains for cross-breeding to make new marijuana strains or brands, maybe the only true way to make a new strain and secondly the plants themselves are fabulous to smoke in their natural form and have recently become very popular amongst both recreational smokers and medical marijuana patients. This dispels a myth that THC content has increased in modern strains of marijuana, as any cannabis landrace will get you very high.
Some of the more famous landrace cannabis strains are from Afghanistan, Africa, Brazil, India, Mexico and Thailand but that's generalizing because according to botany a plant growing from the same strain of seed, such as Jamaica Lambs Bread, for a long enough period of time, without being crossed with another strain, can be known as a landrace. Some of the other best known strain brands are Hindu Kush (pictured), Malawi Gold, or Acapulco Gold, which I recently heard was re-produced by a Dutch grower and brought back to the Coffeeshops in Amsterdam and has become very popular.

I am an Organic Farmer from Ohio and I can't tell you how important this is once you lose these strains they are gone forever.
I love this Plant..

Right on Fred! Do you think enough is being done to preserve the great strains? Should we be talking about creating a global collective seed bank? Maybe I'll ask Danny Danko to weigh in on this topic...
not sure if a collective seed bank is the right idea. though im into it. we should be preserving them, but by people growing the old skool strains.
I am in search of great stock of landraces for conservation, breeding, selecting and stabilising.
If some people are sure of the origins of their landraces seeds, please contact me to know how to process for sending me this rarity. The goal is to preserve all original landraces for the future in good conditions. I am specialize in asian landraces originally from Afghanistan, Pakistan, India, Nepal, China, Ouzbekistan...
If you have some to send please contact me.

Amsterdam is the place you need to go but also I could suggest some sources in B.C. Canada and California. Let me know more about your plans and where you're at now with your project, so I can assist you.
any reliable online sources for landrace seeds?
I recommend TH Seeds and suggest looking in the Attitude Seed Bank - http://www.cannabis-seeds-bank.co.uk/
I had very good experience in the past with the Carnival of Ministry of Cannabis http://www.ministryofcannabis.com
