Myrcene Dominance

Myrcene dominance refers to cannabis chemotypes where myrcene constitutes the primary terpene profile, often exceeding 50% of total terpene content. This monoterpene is commonly associated with earthy, herbal, and sometimes fruity or clove-like aromatic notes. Myrcene-dominant strains frequently appear in indica-leaning lineages, though the terpene itself is not indicative of plant structure or effects. Breeders working with myrcene-dominant parents often select for stable expression across generations. The trait is relevant to both aroma profiling and cultivation consistency in breeding programs.

Breeders use myrcene dominance as a marker for specific aromatic phenotypes and as a stable genetic trait when establishing new lines. Crossing myrcene-dominant parents can help maintain or intensify this terpene profile in offspring, making it a predictable tool for targeted breeding work.
