Myrcene Primary Dominance

Myrcene Primary Dominance refers to cannabis cultivars where myrcene is the most abundant monoterpene, often comprising 30–70% of the total terpene profile. This terpene family is commonly associated with earthy, herbal, and sometimes fruity or clove-like aromas. Myrcene-dominant strains frequently appear across indica and hybrid lineages, and breeders have long selected for this trait due to its stability in cultivation and prevalence in landrace genetics. Understanding myrcene dominance is valuable for lineage work, as it often co-occurs with specific cannabinoid ratios and plant structure characteristics.

Breeders working with myrcene-dominant genetics often report predictable growth patterns and consistent terpene expression across generations. This makes the family useful for stabilizing hybrid lines and developing IBL (Inbred Line) cultivars with reliable aromatic profiles.
