Myrcene Terpene Expression

Myrcene is one of the most abundant terpenes in cannabis, often comprising 20-65% of a strain's total terpene profile. This monoterpene is commonly associated with herbal, earthy, and sometimes fruity or clove-like aromatics. Myrcene-dominant strains frequently exhibit a characteristic peppery-musky baseline aroma that can support secondary notes depending on co-occurring terpenes and cultivar genetics. Breeders working in this category often select for myrcene expression when targeting specific flavor and aroma phenotypes within Indica-leaning and hybrid lineages.

Myrcene expression is a useful phenotypic marker in breeding programs, as it correlates with certain plant growth patterns and is relatively stable across generations within established lineages. Breeders commonly track myrcene levels during selection to maintain or modify the sensory profile of strain families while pursuing other agronomic traits.
