Myrcene Terpenes

Myrcene is one of the most abundant terpenes found across cannabis cultivars, comprising 20-65% of total terpene profiles in many strains. This sesquiterpene is also present in hops, lemongrass, and mango, and is commonly associated with earthy, herbal, and fruity aromatic notes. Lineage records frequently report myrcene-dominant profiles in Indica-leaning and hybrid families, though expression varies significantly based on genetics, cultivation conditions, and harvest timing. Breeders working with myrcene-rich cultivars often select for stability of this trait across generations, as it contributes to distinctive sensory profiles and may influence plant physiology during flowering. Understanding myrcene prevalence helps contextualize breeding goals around aroma, terpene ratios, and chemotype diversity.

Breeders monitor myrcene levels when developing strains for consistent aroma and as a marker of broader terpene expression. Myrcene-forward parents are frequently crossed to explore how this dominant terpene interacts with secondary terpenes, cannabinoids, and plant structure across offspring.
