Enzyme Genotyping

Enzyme genotyping refers to the molecular identification of cannabis plants based on specific enzymatic pathways and their genetic markers, particularly those involved in cannabinoid and terpene synthesis. Rather than phenotypic observation alone, this classification uses biochemical analysis to map the genetic potential for secondary metabolite production. Breeders and researchers employ enzyme genotyping to identify plants carrying desired alleles for cannabinoid synthases (CBDA, THCA), terpene synthases, and other metabolic enzymes before phenotypic expression occurs. This approach enables earlier selection in breeding programs and more precise lineage tracking across generations. Enzyme genotyping can reveal cryptic or recessive genetic traits not visible in plant morphology, supporting more targeted cultivar development.

Breeders use enzyme genotyping to accelerate selection for consistent cannabinoid profiles and terpene composition without waiting for full plant maturation. This molecular data also helps identify heterozygous carriers and rare allele combinations valuable for developing novel chemotypes.
