Krabangkham Farm 'Tiger Tail' Selection 2024 is a domesticate landrace cannabis accession collected by Isabella of the Zomia Collective in Sakhon Nakhon Province, Thailand.
Cultivar
A cultivar is a group of cultivated plants selected for particular characteristics and able to keep those characteristics when propagated by defined means. The word, a contraction of "cultivated variety", is governed by the International Code of Nomenclature for Cultivated Plants (ICNCP), which treats a cultivar as the basic unit of classification for plants in cultivation and requires it to be distinct from other cultivars, uniform in its selected traits and stable, so that those traits persist through the propagation used to maintain it. A cultivar name pairs the botanical name with a cultivar epithet, as in Cannabis 'Finola'.
In Cannabis the cultivar sits among several overlapping ways of naming plant groups that are often confused. It differs from a landrace, a locally adapted population maintained by farmers without formal selection; from a botanical variety, a rank of the wild-plant nomenclatural code applied to naturally occurring forms; from the vernacular strain, a market term with no standing in either code; and from a chemovar, a grouping by measured cannabinoid and terpene chemistry rather than by breeding history. Most Cannabis sold as named "strains" has never been registered or verified as a cultivar, and genetic studies have repeatedly found that shared names do not guarantee shared ancestry.
Whether a plant group qualifies as a cultivar carries practical weight. It determines how the group can be protected under plant breeders' rights, how reliably a grower can reproduce it, and how conservation programmes weigh it against the landraces from which cultivars are ultimately drawn. read more →

Cannabis eradications
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.
