Thc Synthase Dominance
THC synthase dominance refers to genetic expression patterns where the THCAS enzyme pathway is the primary cannabinoid-producing route in a cultivar. This designation is determined by genomic markers and enzymatic activity rather than final cannabinoid ratios, as post-harvest decarboxylation converts THCA to THC. Lineage records frequently report this trait in modern cultivars descended from landrace and hybrid breeding programs focused on THC-type genetics. The presence of active THCA synthase enzyme (versus CBDA synthase) represents a fundamental metabolic commitment during plant development. Understanding this distinction is important for seed breeders selecting parent stock for consistent cannabinoid profiles.

Breeders working in this category prioritize cultivars with stable THCAS gene expression to maintain THC-dominant phenotypes across generations. Marker-assisted selection for THCAS dominance helps stabilize breeding lines and reduce unexpected cannabinoid segregation in F1 and F2 populations.
