Myrcene Dominant Ratios

Myrcene-dominant strains are cannabis lines where myrcene comprises the primary terpene fraction, often representing 40-60% of the total terpene profile. This monoterpene is commonly associated with earthy, herbal, and sometimes fruity or clove-like aromatic characteristics. Myrcene is the most abundant terpene in cannabis overall and frequently appears across both indica and sativa lineages, though certain breeding populations have been selected specifically for elevated myrcene expression. The terpene's prevalence in commercial breeding reflects both historical plant selection and its stability across growing conditions. Understanding myrcene dominance is relevant to breeders working on aroma consistency, terpene profiling, and lineage documentation.

Breeders often select for myrcene dominance when targeting specific aromatic profiles or when developing strains from parent lines known for myrcene-rich chemistry. Stabilizing myrcene ratios across generations requires consistent phenotype selection and environmental controls, making it a foundational trait in many classical breeding programs.
