Agronomic behavior of six non-psychoactive Cannabis sp. genotypes under greenhouse in the high Andean tropics of Colombia. Cienc. Tecnol.

Within the framework of Decree 613 of 2017, which regulates Law 1787 of 2017, the legal production of cannabis for medical and scientific use begins in Colombia. As it is a crop with no legal history in the country, it is necessary to carry out an agronomic evaluation test (AET), through which its stability in a determined subregion is demonstrated, during a complete cycle. This study presents the results of an AET carried out in the Andean zone of moderate cold (from 1800 to 2200 m asl) in the eastern department of Antioquia, Colombia, under plastic cover, with six genotypes of non-psychoactive cannabis (THC < 1%) pre-existing in the seed source registered with the ICA. The evaluation was carried out between September 30, 2019, and January 15, 2020. The genotypes were spatially distributed based on a randomized complete block design, with three replicates per genotype and 20 plants per experimental unit, planted at a density of four plants per square meter. The total fresh biomass (stem, leaves and inflorescences) per square meter presented a general average of 3525.62 g, of which 775.42 g (22 %) corresponded to the flowers. The flowers had an average content of 10.70% CBD and 0.47% THC. These materials are classified as non-psychoactive, in accordance with Colombian regulations, and can therefore be used for any of the purposes established in Section 5 of Decree 613 of 2017.

Keywords : cannabinoids; medical cannabis; characterization; productivity; agronomic evaluation test (AET); tetrahydrocannabinol; cannabidiol.
