Myrcene Terpene Expression

Myrcene is one of the most abundant terpenes in cannabis, often comprising 20–65% of the total terpene profile in certain cultivars. This monoterpene is also found in hops, mangoes, and lemongrass, contributing to earthy, herbal, and sometimes fruity aromatic notes. Lineage records frequently report myrcene-dominant phenotypes emerging from landrace strains and modern hybrids alike. Breeders working in this category often select for high myrcene expression when developing cultivars with particular aromatic signatures. Myrcene-rich genetics are commonly associated with specific flavor and aroma profiles rather than pharmacological effects. Understanding myrcene expression patterns helps cultivators and breeders predict terpene stability across generations.

Breeders monitor myrcene levels during strain development to stabilize desirable aroma profiles and predict phenotypic consistency. High myrcene strains often serve as genetic foundations for crosses aimed at creating cultivars with earthy or herbal characteristics.
