Thc Synthase Phenotype
THC synthase phenotype refers to plants exhibiting the genetic expression of tetrahydrocannabinolic acid synthase (THCA synthase), the enzyme responsible for catalyzing the final biosynthetic step in THC production. Cannabis plants express either THCA synthase or CBDA synthase (or both in minor amounts), which largely determines whether the plant accumulates THC or CBD as its primary cannabinoid. This phenotypic expression is controlled by a single genetic locus, making it one of the most straightforward cannabinoid inheritance patterns in cannabis breeding. Lineage records frequently report this trait as a primary selection criterion in THC-dominant cultivar development. Understanding this enzyme phenotype is foundational for breeders seeking to reliably produce THC-rich or balanced chemotype lines.

Breeders working with THC synthase phenotypes prioritize this trait to establish stable THC-dominant lines and to understand chemotype segregation in F1 and F2 populations. Testing for THCA synthase expression early in breeding cycles allows rapid identification of THC-accumulating individuals, improving selection efficiency across generations.
