What are cannabis landrace strains?
What is a landrace strain and what makes it unique?
Landrace cannabis strains and landrace seeds have held a special place in the cannabis seed collections of old school connoisseurs and breeders. Landrace strains are the original genetic foundations of modern cannabis hybrids. They have evolved naturally over thousands (possibly millions) of years. They slowly adapted perfectly to the local environment, or terroir. This often shaped the properties and features of the various phenotypes in the landrace strains. How many cannabis landrace strains are there? It’s impossible to say, the illegality of cannabis meant that no official historical botanical records exist.
Landrace sativa strains that evolved in warm, tropical jungle environments may show different properties to landrace indica strains which evolved to survive more hostile and barren mountainous habitats. Some of these genetic features are useful to modern cannabis breeders who may want to amplify certain properties in order to create a new modern hybrid.
Many original landraces strains may have a clue to their country of genetic origin in the strain name, such as Durban Poison (Durban, South Africa), Malawi Gold, Thai, Afghani Kush, Mazar etc.
How many landrace weed strains are there?
Where is landrace cannabis from? All modern cannabis strains evolved from the many hundreds of original landrace strains. In recent decades, cannabis breeders have bred extensively with original landrace strains in order to improve or amplify their best features.
This has resulted in most landrace strains being somewhat changed from their original pure genetic state. This will sound disappointing to the old school purists. But the breeding work was done for good reasons. Without it, many landrace strains would simply be rejected by modern growers for e.g. being low yielding or with low THC levels. Most of todays cannabis growers don't mind the fact that landrace sativa seeds were crossed to create some modern sativa crosses with shorter bloom times than e.g. the original landrace Thai sativa.
Where to find landrace strains in the wild? Cannabis still grows in the wild in many tropical climates and mountainous areas. These are probably the best places to find landrace weed and landrace seeds.
If harvest yields/consistency of original landrace strains are improved and THC levels increased, the average indoor grower might consider that to be solid breeding progress. But original cannabis seed companies like Dutch Passion still retain collections of pure unadulterated landrace seeds for future generations.
Many cannabis lovers are torn between the romantic ideal of retaining all landrace strains in their original pure genetic form and the modern desire to maximise yields, taste & potency whilst minimising bloom times. Some growers assume that landrace strains are fundamentally superior to modern strains, yet it should be said that many landrace strains simply lack the cannabinoid content and other features (heavy yields, fast bloom times) that many modern growers consider mandatory.
Landrace cannabis seeds have a fond place in the heart of many cannabis growers. But it’s also fair to say that many of todays cannabis growers perhaps prefer the properties and features of modern cannabis seeds, which may contain landrace genetics. But the best contemporary cannabis seeds also tend to have many of the features demanded by modern growers such as fast bloom times, heavy harvests, high THC levels etc.
Landrace sativa strains:
Landrace sativa strains often originated in Asia and North Africa. The enjoyable effects meant that they were helped on their way around the world by humans and got an early introduction to the west. Once they reached the Americas, landrace sativa seeds thrived in warmer southern states. They grew taller, with greater internodal distances and stretch compared to other types of cannabis. These landrace sativa strains simply didn't do as well at more northern latitudes until they were hybridised with other genetics. Some of the original landrace sativa seeds included the following:
- Durban Poison from Africa (Malawi & Kilimanjaro landrace strains are other examples)
- Acapulco Gold from Mexico
- Lambs Bread from Jamaica
- Panama Red, Punto Rojo (a.k.a. Tierra Adentro) & Colombian Gold from South America
- Thai & Chocolate Thai strains from Asia
Landrace indica strains:
Landrace indica strains are thought to have evolved in the tough, rugged mountain ranges of Afghanistan, India, Nepal and Pakistan. Having to cope with a cooler and less forgiving climate, landrace indica strains tend to be shorter, more compact and resinous than landrace sativa strains. Due to climatic pressures and short summers they tend to bloom faster than landrace sativa strains too. Afghan landrace flowering time can be as little as 7-8 weeks in photoperiod feminised seeds.
Landrace indica genetics saw increasing popularity as hippy travellers began visiting these regions in the 1960’s, returning home with landrace indica seeds. Conflict in the 1970’s saw many international military personnel also return landrace indica seeds to the west. Some original landrace indica strains include the following:
- Afghani (Pure Afghan genetics coming from various mountainous areas in Afghanistan)
- Hindu Kush
- Lashkar Gah
Landrace ruderalis strains:
Ruderalis cannabis was largely forgotten until autoflowering cannabis seeds became so popular. Ruderalis often stays very short, reaching just 0.5m - 1m tall. Ruderalis is often found in places with harsh climates and short growing seasons such as Siberia and Northern Europe. THC levels are very low in landrace ruderalis strains, but that hasn't stopped genetic specialists using ruderalis for breeding experiments with hemp and cannabis.
The onset of ruderalis bloom is determined by age rather than light conditions and it is this which differentiates ruderalis strains from all others. This ‘automatic blooming’ trait is necessary since the days can have 20 hours of daylight (or more) at extreme latitudes. Automatic flowering genetics have been taken from landrace ruderalis strains and used in modern autoflower seeds.
Autoflowering cannabis seeds are now a firm part of cannabis culture. Many people grow their own marijuana using autoflower seeds. Autoflower seeds have developed a reputation for being the easiest, simplest and fastest way to grow top quality cannabis with ruderalis genetics. Some examples of popular THC rich autoflower strains are:
- Auto Mazar. Great for indoor or outdoor growers, with genetics from the Mazar-i-Sharif region
- Auto Blueberry. Original Blueberry genetics, THC rich, often ready 8-9 weeks after seed germination.
- Auto Cinderella Jack, with THC levels over 25% is this the world's strongest autoflower?
- Auto Ultimate. She may take a little longer from seed to harvest, but this may well be the worlds best yielding autoflower seed.
- Think Different. Since her launch, Think Different has had more repeat buyers than almost any other Dutch Passion strain. Superb combination of potency and yield.
True landrace strains remain relatively rare. That’s not because seed companies enjoy deliberately mixing landrace genetics with modern genetics. It’s because cannabis growers tend to be quite picky about the cannabis seeds which they grow. Most weed growers only buy a few cannabis seeds each year for a couple of grows.
How do you know if a cannabis strain is a true landrace?
The discerning cannabis seed buyer usually has quite specific requirements for their autoflower seeds or feminised seeds. Often they want a specific type of genetic background with demanding performance features. That could be, for example, a fast auto harvest with high THC levels. You could try to source some landrace ruderalis seeds which would provide you a rapid crop. But if you want high THC levels as well you would need to buy some modern autoflower seeds. Landrace ruderalis seeds simply wouldn’t provide the potency. That principle runs through many of the landrace seed options. They may offer some of the features wanted by the grower, but not necessarily all of them.
That’s why so few true landrace genetics are on offer, most people are not that interested in growing them. Landrace genetics remain important among cannabis breeders looking to create a new strain. But unfortunately landrace genetics tend to be of less useful practical value to the modern home grower. That said, there are plenty of landrace genetics in the breeding collections of the older seed companies where the original genetics remain of great interest.
If you want to buy some landrace seeds how do you know if a strain is landrace? Can you trust the claimed landrace strains list from a breeder? As with most cannabis seeds on sale today, the buyer simply has to trust the vendor claims. It helps if you choose a cannabis seed company with a reputation you can trust and a successful track record established over many decades. Choose your cannabis seeds carefully and enjoy growing your next crop!
Best landrace cannabis seeds from Dutch Passion
Dutch Passion were formally established in 1987, but they were informally gathering cannabis seeds and genetics from around the world since the 1970’s. This has allowed the Dutch Passion breeders an unsurpassed gene bank with some of the best landrace strains including African landrace strains which supplied the genetics for Durban Poison and Power Plant. The best of the landrace marijuana genetics are safely preserved in Dutch Passion’s deep freeze where they are occasionally revived and used in modern breeding projects.
Genetics from the best of the landrace weed strains have been used extensively when breeding modern strains. Girl Scout Cookies, for example, uses Durban Poison genetics. The following Dutch Passion strains are all largely based on landrace genetics with only a modest amount of modern tweaking.
Mazar, Indica dominant Afghani Strain with very high THC levels
What is the most consistent landrace strain? Many would say that accolade should go to Mazar. This is an indica dominant Afghani with a famously powerful vape/smoke and penetrating pungent hash aromas. Mazar genetics were sourced from the Mazar-i-Sharif region. This landrace strain is known for being tough, hardy and easy to grow in just about all grow conditions. To improve yields, some Skunk genetics were introduced, though this doesn't detract at all from the superb taste, aroma and long lasting high.
Mazar feminised seeds take around 8 weeks in bloom. They are also available in regular cannabis seeds and are proud members of the Dutch Passion very high THC seed collection. This means that you can expect THC levels up to 20%, possibly a touch higher in optimised conditions. Mazar seeds are part of the Afghani Kush seed collection.
Fans of autoflower seeds should check out Auto Mazar. Auto Mazar grows well under 20 hours of indoor light, taking around 11 weeks to grow from seed to harvest. Auto Mazar is also particularly recommended for outdoor growers. She takes around 100 days to grow from seed to harvest outdoors, her landrace Mazar genetics ensure she is tough enough to deliver harvests even in poor outdoor conditions.
Durban Poison, stress-busting South African sativa
Durban Poison is a stunningly powerful South African sativa. This well known Dutch Passion strain is famous for it’s ultra relaxing anti-anxiety high. Stress and tension simply melt away after a few vapes of this THC rich, resin-drenched beauty.
Originally a landrace strain which evolved in South Africa, Durban Poison seeds were taken to Europe in the 1980’s by Dutch Passion to select some parents which would provide offspring suitable for outdoor European cultivation. During this outdoor selection process a small amount of unknown indica genes were introduced to Durban Poison. The indica genetics didn't substantially change the results from Durban Poison. The soaring sativa high is special enough to create a generation of repeat growers, some of whom will grow nothing else.
With unusual aniseed, cloves, lemon and liquorice aromas together with heavy yields, Durban Poison is equally at home indoors or outdoors. Outdoors, she can grow at Dutch (or Southern UK) latitudes. Durban Poison is ready to harvest after around 8-9 weeks of 12/12 indoor bloom. THC levels are high thanks to the incredible resin production and the seeds are part of the Dutch Outdoor collection
Power Plant, African sativa genetics with stunning yields and ease of growth
Anyone looking for an easy to grow sativa with generous yields and a deliciously enjoyable high should take a close look at Power Plant. This unusual African sativa bends a few rules when it comes to delivering heavy harvests of THC rich buds. The plants are ready to harvest much quicker than most sativas. In good conditions, Power Plant is ready to harvest after around 8 weeks of bloom. Yields are very generous too. THC levels are high, Power Plant seeds are part of the Dutch Passion Classics collection.
Power Plant isn't as stretchy as some other pure sativas (like Desfrán for example) and can produce medium height plants with notably chunky blooms. It’s a variety that you can grow well in a SOG (Sea Of Green) system with little (or no) vegetative growth.
