Featured article

INRA Maroc is the Moroccan national agronomic research institute, the Institut National de la Recherche Agronomique, and holds a collection of plant genetic resources that it reports to the FAO's Global Information System on Plant Genetic Resources for Food and Agriculture (GLIS). Its FAO WIEWS institute code in GLIS is MAR088. Its address in the passport data is Avenue Ennasr, Rabat. DataCite names the conserving unit INRA CRRAS.

On 15 January 2026 INRA Maroc registered 106 Cannabis sativa samples in GLIS under DOIs in the 10.18730 series, with accession numbers MGB 40087, 72583 to 72644 and 75941 to 75983. All 106 carry the biological status traditional cultivar or landrace. All but one were collected at sites in the Rif Mountains, in the provinces of Al Hoceima, Chefchaouen, Taounate, Ouezzane and Larache, in September 2021 and May 2023. They were accepted into the collection in October 2022 and April 2024.

The passport data give a site and a coordinate for most samples and carry no collector or plant description. MGB 40087 was accepted in August 2009; its passport data give no site, date or collector, so nothing places it in the Rif.

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.
