landrace genetics

The diaspora of prehistoric human beings saw the global distribution of the infinitely useful cannabis plant into every climatic region on the globe. Once established, plants mutated over the thousands of years to form what we enjoy today as landraces. Heirloom varieties of cannabis that breed true everytime and can be considered “pure” strains.

The plant typifies the sativa silhouette. It is lanky with a fair distance between internodes. Leaves are thin with heavily serrated fingerlettes, that do not overlap and have a tendency to droop. With contemporary husbandry well grown examples of Mexican sinsemilla flowers are by no means “light and fluffy”, they are densely packed with resins. The branches grow long, with the flower formations distributed along the branches and central cola, taking eleven to fourteen weeks to mature.
Cannabis is thought to have evolved on the steppes of Central Asia. Human beings have exploited this multi-purpose plant for over twelve thousand years and cannabis has played an important role in the development of civilizations throughout the eons. Cannabis is thought to be partly responsible for the early rise of Chinese civilization and ingenuity. The invention of hemp paper some 2,200 years ago provided the vehicle for recording knowledge that was able to be passed down through the ages, having a similar effect on Chinese culture the Gutenberg press had on European culture 1,500 years later.

Used by breeders to help reduce flowering times and increase bud density of tropical sativas or is that using sativas to increase the cerebral effects of quick maturing indicas? Either way, Afghani cannabis has played a major role in the development of contemporary strains.
The familiar bouquet of the AK lineage has been given a complex terpene tweak. An intensified smooth spiciness is quickly followed by a lush fruity rush in a pine forest on a warm spring afternoon. Experienced cannabis connoisseurs will enjoy the pronounced eye-opening sativa effects. Bright, uplifting and incredibly clear, a luscious well cured 18% THC bud is a great way to start the day. The mellow physical after-effects encourage serene smiles from everyone who has the Green AK XL experience.
As with Mexico, cannabis has been a staple plant in Colombia since before recorded history. It has been in the region long enough to adapt to local climates and evolve several stable landraces. These are classed into two categories: highland and lowland cannabis. Lowland was the typical plant grown commercially by cartels in the seventies to service the increasing demand from the US. Highland grows best above 800 metres and below 2,000 metres altitude and is the preferred breeding stock, as it is far more psychoactive, than the coastal grown cousin.
Green AK XL is a primo example of the cannabis growers art. This fast maturing and heavily flowered plant is a totally tricked out AK-47. Adding Mexican and Thai genetics to the already buzzing and cerebral Colombian sativa gives the familiar AK effects a delicious connoisseurs twist. The indica component is given a density re-boost by backcrossing with another Afghani. This has produced a stable sativa-dominant plant, that displays extraordinary hybrid vigour with high yields and a quick 55 day maturation time.
The region has been at war now for over twenty five years, so chances of getting in, wandering around on a cannabis seeking odyssey and getting out alive are very slim. The Afghani seeds of legend used to create such classics as Skunk and White Rhino were smuggled out of Afghanistan in the mid eighties before fighting became too dreadful with Russia. These prized seeds ended up in Europe and the States and are jealously guarded to this day.

When talking about Mexican landraces it is generally accepted that the plants are the legendary Oaxaca sativa.

Landraces are the key to the contemporary cannabis genetics. We look at Mexican Colombian Thai Afghani and how we use them in breeding.
