Secondary Cannabinoid Expression

Secondary cannabinoid expression refers to the cultivation and selection of cannabis plants bred to produce elevated levels of non-THC/non-CBD cannabinoids such as CBG, CBC, CBDV, or THCV. While THC and CBD dominate most commercial cultivars, secondary cannabinoids are often present in trace amounts; selective breeding programs isolate and amplify these minor pathways. Lineage records frequently report that cultivars from landrace populations or specific genetic backgrounds—such as African sativas or Hindu Kush derivatives—naturally express higher secondary profiles. Understanding secondary cannabinoid inheritance patterns remains an active area in cannabis breeding research, with breeders working in this category focusing on stable trait fixation across generations.

Breeders pursuing secondary cannabinoid expression typically employ backcrossing, test crosses, and marker-assisted selection to identify and stabilize plants with consistent minor cannabinoid production. Stabilizing these traits is challenging because secondary cannabinoid pathways are often polygenic and can be environmentally influenced, requiring careful phenotyping and multi-generational sele
