Landrace.wiki
The open database for landrace cannabis populations, their genetics and the traditional knowledge that sustains them.
Landrace.wiki is the open database for landrace cannabis—populations, their genetics, and the knowledge around them. Browse documented accessions, track conservation efforts, and contribute to preserving genetic diversity before it’s lost.

We are witnessing the rapid disappearance of traditional cultivation knowledge and genetic diversity in cannabis. These landrace populations represent thousands of years of natural and human selection, containing unique genetic traits and chemical profiles. Systematic documentation and conservation efforts can serve as a bridge—preserving irreplaceable genetic heritage while supporting traditional communities and advancing our understanding of this remarkable plant.

Cannabis sativa
Cannabis sativa L. is an annual flowering plant in the family Cannabaceae, first formally described by Carl Linnaeus in 1753. It is the type species and, under the monotypic treatment that is most widely cited in the cannabis-specific literature, the sole species of the genus Cannabis. The species encompasses cultivated and wild forms used for fibre, seed and drug production and has been cultivated across most of the inhabited world since antiquity.
Cannabis sativa is dioecious, wind-pollinated and photoperiod-sensitive. Wild and feral populations persist across temperate Asia and the species has naturalised in disturbed habitats on every continent except Antarctica.
Small and Cronquist (1976) divided the species into two subspecies: subsp. sativa (cultivated and wild hemp) and subsp. indica (drug-type forms described as a separate species by Lamarck in 1785). Cultivation falls into three categories: fibre cultivars selected for tall stems with high bast content; oilseed forms grown for achene production; and drug-type plants grown for the resinous pistillate inflorescence, which accumulates THC, CBD and other cannabinoids. Traditional landraces are often multi-purpose, yielding multiple products from a single planting. read more →
