Terpene Dominant Phenotypes

Terpene-dominant phenotypes are cannabis plants exhibiting notably high volatile organic compound (VOC) profiles relative to cannabinoid content. These expressions occur when environmental pressure, genetic predisposition, or phenotypic variation favors terpene accumulation over THC/CBD synthesis. Breeders and cultivators document terpene dominance as a distinct phenotypic marker within single seed lines, often appearing inconsistently across offspring. This trait is particularly relevant in breeding programs focused on aromatic profiles, flavor expression, or non-intoxicating cultivar development. Terpene-dominant plants remain genetically identical to cannabinoid-dominant siblings but express measurably different chemical ratios.

Breeders selectively stabilize terpene-dominant phenotypes to create cultivars emphasizing aroma and flavor complexity. Selecting and backcrossing these phenotypes across generations helps lock in high VOC expression as a heritable trait, supporting both craft breeding and aroma-focused commercial development.
