Major Terpene Dominance

Major terpene dominance describes cannabis cultivars where one or two terpenes comprise a notably elevated percentage of the total terpene profile—typically 30% or higher of the volatile fraction. This classification emerged from analytical cannabinoid and terpene testing, allowing breeders and researchers to organize strains by their chemical fingerprints rather than subjective aroma descriptors. Strains with dominant terpene profiles often show consistency across harvests when grown under controlled conditions, making them valuable for breeding programs targeting specific aromatic or flavor outcomes. Common dominance patterns include myrcene-forward, limonene-dominant, and pinene-rich lineages, each reflecting different genetic backgrounds and cultivation histories. Understanding terpene hierarchy helps breeders stabilize desirable traits and supports seed bank classification systems.

Breeders selectively cross cultivars exhibiting major terpene dominance to establish or reinforce these traits in offspring, creating predictable phenotype libraries. Terpene-focused breeding supports both commercial standardization goals and preservation of regionally distinct landrace characteristics.
