Thc Cannabinoid

THC (tetrahydrocannabinol) is a cannabinoid—not technically a terpene—but fundamental to cannabis genetics and breeding selection. It is the primary psychoactive compound in cannabis, synthesized through the plant's cannabinoid biosynthetic pathway. THC content varies widely across cultivars due to genetic inheritance, environmental factors, and breeding practices. Understanding THC production helps breeders develop stable, reproducible lineages for both research and regulated markets. Modern seed catalogs often report THC ranges based on third-party testing data, though field expression remains variable.

Breeders select for THC production by tracking parental cannabinoid profiles and stabilizing high-THC phenotypes across generations. Quantitative genetics shows THC synthesis is polygenic, requiring multi-generational selection to achieve consistent potency in F1 hybrids and inbred lines.
