Myrcene Dominant Plants

Myrcene-dominant plants are cannabis genetics where myrcene comprises the largest portion of the terpene profile, often exceeding 50% of total terpene content. Myrcene is one of the most abundant terpenes in cannabis and is also found in hops, mango, and lemongrass, contributing herbal and earthy aromatic notes. Lineage records frequently report myrcene dominance in Indica-leaning and landrace-derived strains, particularly those with Southeast Asian or Afghan heritage. Breeders working with myrcene-dominant lines often select for high-terpene phenotypes that express herbal, dank, or spicy-sweet profiles. The presence of myrcene at elevated levels may influence flower maturation timing and cannabinoid expression during cultivation, making it a key marker in breeding programs focused on terpene stability.

Breeders use myrcene-dominant phenotypes as parent material to establish consistent aromatic signatures and to explore potential interactions between myrcene and other minor terpenes. Selecting for myrcene dominance requires multi-generational testing and gas chromatography analysis to ensure stable terpene ratios across seeds and clones.
