High Myrcene Profiles

High myrcene profiles refer to cannabis cultivars where myrcene comprises a substantial portion of the terpene composition, often 0.5% or higher by dry weight. Myrcene is the most abundant terpene across many cannabis varieties and is also found in hops, mango, and lemongrass. Lineage records frequently report myrcene-dominant expressions in Indica-associated strains and many popular cultivars from South Asian and Afghan breeding programs. The aroma is commonly associated with earthy, herbal, and spicy notes, sometimes with subtle fruit undertones. Breeders working in this category often select parent plants based on gas chromatography (GC) or high-performance liquid chromatography (HPLC) testing to maintain or enhance myrcene levels across generations.

Myrcene's prevalence makes it a useful phenotype marker for breeders establishing consistent aromatic profiles and selecting for specific plant structure traits, as high myrcene is frequently correlated with shorter flowering times and denser growth patterns. Selection for myrcene-dominant chemotypes allows breeders to predict terpene stability in F1 and stabilized lines.
