Terpene Dominance Classification

Terpene dominance classification is a systematic approach used by cannabis breeders and researchers to categorize strains based on their most abundant volatile compounds. Rather than focusing on a single terpene, dominance classification examines the hierarchical profile—which terpenes appear in highest concentrations and how they interact. This method helps breeders predict aroma characteristics, understand genetic expression patterns, and communicate chemotype data across different growing conditions. Dominance profiles are influenced by genetics, environmental factors (temperature, light, soil composition), and harvest timing, making them variable even within the same cultivar. Breeders working in this category use dominance profiles to stabilize desired aromatic expressions across seed generations and to develop strains with consistent sensory attributes.

Breeders use terpene dominance classification to select parent plants with complementary profiles, predict offspring chemotypes, and create reproducible aromatic lineages. Understanding which terpenes consistently express as dominant helps identify stable traits suitable for seed development and commercial stabilization.
