An In-Depth History of Cannabis Seed Breeding

An In-Depth History of Cannabis Seed Breeding

Cannabis seed breeding has a complex, intricate history that spans thousands of years, across continents, cultures, and legal landscapes. In delving deeper into this fascinating story, we gain a better understanding of the diversity, adaptability, and potential of the cannabis plant. At the heart of it, Malta, with its recent legalization of cannabis, is now ready to make its own contributions to this rich tapestry.

The Seed of Civilization: Cannabis in Antiquity

The use of cannabis traces back to the cradle of human civilization. Archaeological evidence suggests that ancient societies in Central Asia and Eastern Europe used cannabis as a food source, a textile fiber, and a ritualistic plant as far back as 5000 B.C. In these early societies, cultivation likely revolved around practical considerations—plants with the most usable fiber or highest seed yield were likely preferentially grown. This early form of selective breeding was the genesis of the domesticated cannabis plant varieties we see today.

Middle Ages: Cannabis Travels the Silk Road

As human civilization developed and expanded, so did the use of cannabis. The plant made its way along the Silk Road trade routes from China to the Middle East and Africa. By the Middle Ages, cannabis was well known for its medicinal properties throughout the Islamic world.

19th Century: Industrial Hemp and the Cannabis Diaspora

The 19th century saw a significant increase in the global cultivation of cannabis, primarily for industrial purposes. Hemp, a cannabis variety grown for its fiber, became a valuable global commodity. During this period, cannabis made its way to the New World. North American farmers were even legally required to grow hemp in colonies like Jamestown due to its value as a source of fiber for ropes, sails, and paper.

Cannabis also reached South America and the Caribbean through the slave trade, while the British introduced Indian cannabis genetics to Africa and Australia during colonial times. These migrations further diversified the global cannabis gene pool.

Early 20th Century: The Winds of Prohibition

The early 20th century brought a seismic shift to the cannabis world. Societal attitudes towards cannabis changed drastically, culminating in widespread prohibition and criminalization. The 1937 Marijuana Tax Act in the U.S. led the way, with many countries following suit.

This era had profound effects on cannabis seed breeding. With formal cultivation largely prohibited, many breeding efforts went underground. Meanwhile, prohibition laws disrupted traditional cultivation practices in many regions, leading to the loss of countless classic strains as well as landrace strains.

Despite these constraints, breeders began experimenting with the ruderalis strains native to Eastern Europe and Russia. These plants were not known for their potency, but they did have one key trait: they were autoflowering, meaning they flowered based on age rather than light cycles. This trait would later prove crucial in the development of modern autoflowering strains.

Mid to Late 20th Century: Counterculture and Cannabis Hybrids

The mid to late 20th century marked the advent of modern cannabis breeding. As counterculture movements of the 1960s and 1970s embraced cannabis, breeders began to experiment with crossbreeding strains to create hybrids with various desired characteristics.

Landrace strains from Afghanistan and Thailand made their way to the West, where they were crossbred with local varieties to produce some of the first modern hybrids. These strains, including the famous Haze and Skunk varieties, were often more potent and easier to grow than their landrace ancestors.

Meanwhile, pioneering breeders like Neville Schoenmaker established the first cannabis seed banks, enabling hobbyist growers to buy the right seeds and grow their cannabis at home. The legalization of cannabis in the Netherlands in 1976 provided the perfect environment for these early seed banks, such as the legendary Seed Bank of Holland, to flourish.

The 1980s and 1990s saw further advances in breeding, including the development of the first stable autoflowering strain, Lowryder, by a breeder known as The Joint Doctor. This development revolutionized cannabis cultivation, as autoflowering strains could be grown year-round, regardless of light cycles.

21st Century: High Tech Breeding and Legalization

In the 21st century, cannabis seed breeding has been transformed by both legal changes and technological advancements. The rise of legal medical and recreational cannabis in various regions worldwide has opened up new opportunities for breeders.

Technologies such as DNA sequencing and genetic mapping have also dramatically changed the breeding landscape, enabling breeders to select for specific traits with greater precision than ever before.

Meanwhile, the industry has seen a proliferation of seed companies developing and marketing new strains. Companies like Canopy Growth and Aurora Cannabis in Canada, Barneys Farm and Green House Seeds in Europe, have continued to innovate, creating strains with diverse flavor profiles, effects, and medical benefits. Nowadays you can find all sorts of strains, whether you choose to grow your own weed or buy from a local dispensary.

Malta: A New Chapter in Cannabis History

With the recent legalization of cannabis, Malta is poised to add its unique chapter to the history of cannabis seed breeding. At, we're excited to be part of this new era in Maltese cannabis cultivation. Our aim is to contribute to the diversity and richness of cannabis genetics, developing new strains that are perfectly adapted to Malta's unique climatic conditions and the needs of Maltese growers. We believe that the combination of Malta's favorable growing conditions and the passion of local breeders will soon lead to the emergence of unique, endemic Maltese cannabis strains.

The Future of Cannabis Seed Breeding

As we look towards the future, the possibilities for cannabis seed breeding seem limitless. The combination of legal reform, technological advancement, and ongoing research promises a wealth of new strains, each tailored to specific uses, environments, and personal preferences.

The history of cannabis seed breeding tells a story of human innovation and the incredible adaptability of this remarkable plant. As we continue to explore and unlock the potential of cannabis, we stand on the shoulders of countless breeders who have contributed to the rich diversity of cannabis genetics we see today.
