Thc Tetrahydrocannabinol

THC (tetrahydrocannabinol) is the primary psychoactive cannabinoid in cannabis, produced in trichomes on flowers and leaves. Its biosynthesis follows a well-documented enzymatic pathway beginning with geranyl pyrophosphate and progressing through olivetolic acid condensation. Lineage records and breeding documentation frequently report wide variation in THC accumulation across cultivars, influenced by genetics, environment, and harvest timing. Most modern breeding programs track THC content through cannabinoid profiling to meet regional regulations and consumer market demands. Understanding THC chemistry and inheritance remains foundational to cannabis genetics work.

Breeders select for THC-dominant phenotypes using parent stock with established cannabinoid profiles, often stabilizing high-THC lines through selfing or backcrossing. Cannabinoid testing during phenotype evaluation helps identify and isolate plants expressing desired THC ratios relative to CBD and minor cannabinoids.
