Thca Synthase Dominant
THCA Synthase Dominant refers to cannabis plants expressing elevated levels of the enzyme THCA synthase, which catalyzes the conversion of cannabigerolic acid (CBGA) to tetrahydrocannabinolic acid (THCA) during biosynthesis. Lineage records frequently report this trait clustering in lines derived from Central Asian and South Asian landraces, though modern cultivars across multiple geographic origins may express this characteristic. Plants with dominant THCA synthase activity typically channel a larger proportion of their cannabinoid biosynthetic pathway toward THCA production rather than CBDA or other minor cannabinoid pathways. This enzymatic expression is heritable and forms a foundational genetic distinction used by breeders to classify chemotype populations and predict cannabinoid profiles across generations.

Breeders working with THCA Synthase Dominant germplasm use this trait as a primary selection criterion for developing high-THC cultivars and for understanding cannabinoid inheritance patterns. Understanding THCA synthase dominance also helps breeders predict stability of cannabinoid ratios and plan crosses intended to maintain or shift chemotype expression.
