Myrcene Expression

Myrcene Expression refers to cannabis cultivars selected or bred for elevated myrcene terpene profiles, a monoterpene commonly associated with earthy, herbal, and musky aromatic qualities. Myrcene is one of the most abundant terpenes across cannabis genetics and appears across diverse strain families and chemotypes. Plants exhibiting high myrcene expression often display robust volatile production during flowering and cure stages. Lineage records frequently report myrcene dominance in landrace derivatives, particularly those with Afghani or Southeast Asian ancestry. Breeders working in this category typically employ selection or backcrossing to stabilize myrcene-forward phenotypes. Understanding myrcene expression remains foundational to cannabis chemotype classification and aromatic profiling.

Breeders target myrcene expression through phenotypic selection during flowering assessment and gas chromatography testing. High-myrcene lines serve as genetic anchors for creating aromatic consistency across hybrid crosses and are valued in breeding programs emphasizing terpene stability.
