Terpene Dominant Expression

Terpene-dominant expression refers to cannabis cultivars where volatile aromatic compounds are notably pronounced relative to cannabinoid profile. In breeding contexts, this trait describes plants that produce heightened terpene concentrations or distinctive terpene ratios, often independent of THC/CBD levels. Breeders selectively work with terpene-dominant lines to establish stable aromatic phenotypes and explore chemotype diversity. This classification is commonly used in lineage documentation to distinguish plants valued for aroma complexity rather than cannabinoid potency alone. Terpene expression can be influenced by genetics, environment, harvest timing, and post-harvest handling, making it a key variable in breeding programs focused on sensory profiling.

Breeders targeting terpene-dominant phenotypes use selective crosses and pheno-hunting to isolate and stabilize high-terpene genotypes. This approach supports development of aromatic heirloom lines and chemotype libraries distinct from THC-maximized cultivars.
