Terpene Dominance Types

Terpene dominance types categorize cannabis strains by their most abundant volatile aromatic compounds, which develop during flowering and vary based on genetics, environment, and harvest timing. Breeders and researchers identify these profiles through gas chromatography and sensory evaluation, noting patterns like myrcene-dominant (earthy, herbal), limonene-dominant (citrus), or pinene-dominant (pine, fresh) phenotypes. Dominance hierarchy—which terpenes rank first, second, third—often correlates with parent lineage and can shift slightly between phenotypes of the same strain. Understanding terpene dominance helps breeders select parents for consistent aromatic expression and allows cultivators to recognize strain stability. These classifications are descriptive botanical categories, not predictors of effect or potency.

Breeders use terpene dominance profiles as a selection criterion when stabilizing new lines or crossing for specific aromatic traits. Tracking dominance patterns across generations helps identify which parent contributed particular volatile profiles and informs decisions about backcrossing or outcrossing for trait consistency.
