Thc Tetrahydrocannabinol

Tetrahydrocannabinol (THC) is the primary psychoactive cannabinoid in cannabis, distinct from terpenes but frequently discussed alongside the aromatic compound profile of cultivars. While terpenes are volatile organic molecules responsible for aroma and flavor, THC is a cannabinoid produced in the plant's glandular trichomes. Lineage records and breeding documentation consistently track THC concentration as a core genetic marker, often correlating with specific parent genetics and environmental conditions. Breeders working in regulated markets use THC profiling to classify strain families and predict expression patterns across generations. Understanding THC biosynthesis pathways helps contextualize how cultivar selection and growing practices influence final cannabinoid ratios.

Professional breeders track THC inheritance patterns through pedigree records to develop stable F1 and stabilized lines. Selection for THC concentration, onset profile, and ratio to other cannabinoids like CBD represents a primary breeding objective in most commercial programs.
