Myrcene Dominant Chemotypes

Myrcene-dominant chemotypes are cannabis varieties where myrcene comprises the largest proportion of the terpene profile, often exceeding 30-50% of total monoterpenes. This sesquiterpene is commonly associated with earthy, herbal, and sometimes fruity or clove-like aromas. Myrcene occurs naturally across many plant families and is frequently reported in both indica and sativa lineages, though breeding records suggest higher concentrations in certain indica-leaning lines. The prevalence of myrcene-dominant chemotypes in commercial cultivation stems partly from its stability across growing conditions and its historical presence in foundational cannabis genetics. Understanding myrcene-dominant varieties is relevant for breeders selecting parent plants and for cannabinoid/terpene profile documentation.

Breeders working with myrcene-dominant genetics often use these strains as parent material when seeking stable terpene expression across generations or when combining with other chemotypes for flavor complexity. Myrcene's presence can influence flowering time and plant vigor in breeding programs, making it a phenotypic marker for lineage tracking.
