An appellation, in full an appellation of origin, is the geographical name of a country, region or locality used to designate a product from that place whose quality or characteristics are due exclusively or essentially to its geographical environment, natural and human factors included. The definition is that of the Lisbon Agreement of 1958, which protects a registered appellation against usurpation or imitation, even where the product's true origin is stated or the name is used in translation.

California provided for appellations of origin for cannabis in its 2016 legalisation. Its Department of Food and Agriculture has since written regulations for them. The geographer Pierre-Arnaud Chouvy has argued since 2020 that the kif and hashish of Morocco's Rif, made from the kif landrace, should receive a protected designation of origin. read more →

Comparison of self-pollination and intercrossing for feminized seed production in Thai Hang Kra Rok cannabis (Cannabis sativa L.) landrace

Compares selfing with intercrossing for producing feminized seed from two Thai landrace accessions of Hang Kra Rok cannabis, one from Bangkok and one from Sakon Nakhon. Female cuttings were treated with colloidal silver to induce male flowers, and the progeny were grown in a plant factory with artificial lighting. Both selfed lines and the Sakon Nakhon by Bangkok cross gave 100% female plants, while the reciprocal cross produced one hermaphrodite (5.6%). Dry inflorescence weight did not differ between treatments. The Bangkok selfed line had the highest THC content at 6.58%. The plants were grown under artificial light, so the chemistry is not field chemistry.
