Terpene Co Dominance

Terpene co-dominance refers to cannabis cultivars expressing two or more terpenes at roughly equivalent concentrations in the volatile profile, rather than a single dominant terpene. Classic examples include strains where limonene and myrcene appear in near-parity, or where pinene and caryophyllene co-express at significant levels. This pattern is common in many modern hybrids and is often the result of crossing parents with different terpene-dominant chemotypes. Co-dominant terpene profiles can create aroma and flavor complexity that differs from either parent strain alone. Understanding terpene co-dominance helps breeders predict and select for desired sensory characteristics across generations.

Breeders targeting terpene co-dominance typically cross lines with complementary but distinct volatile profiles, then select offspring that maintain balanced secondary metabolite expression. This approach allows for design of cultivars with layered aromatic profiles and consistent sensory traits across production batches.
