Secondary Terpene Dominance

Secondary Terpene Dominance refers to cannabis cultivars where non-limonene, non-myrcene terpenes (such as caryophyllene, pinene, humulene, or linalool) constitute the primary aromatic profile rather than serving as minor components. In traditional classification, these compounds were considered supporting notes; cultivars exhibiting secondary terpene dominance flip this hierarchy, making them valuable for understanding terpene expression variation across populations. This trait emerges through selective breeding and appears influenced by both genetics and cultivation conditions. Breeders increasingly isolate and stabilize lines showing pronounced secondary terpene profiles to expand the sensory and phytochemical diversity available within breeding stock.

Breeders working with secondary terpene dominance often use these lines as foundation genetics to develop cultivars with novel aromatic signatures and to study terpene heritability across generations. Crosses involving secondary-terpene-dominant parents frequently produce F1 and F2 offspring with varied terpene hierarchies, making them useful for mapping terpene expression loci.
