Myrcene

Myrcene is one of the most abundant terpenes found across cannabis varieties, though it also appears widely in hops, bay leaves, and mango. In cannabis flower, myrcene often comprises 20–65% of the total terpene profile, particularly in indica-leaning cultivars. This monoterpene is characterized by an earthy, herbal aroma with subtle fruity or clove-like notes. Breeders and chemotype researchers frequently document myrcene as a marker of traditional landrace genetics, especially those originating from South Asia and the Hindu Kush region. Understanding myrcene prevalence helps contextualize cultivar aroma profiles and breeding lineage across modern and heritage seed stock.

Myrcene-dominant cultivars are commonly selected in breeding programs targeting specific aroma profiles and cannabinoid expression. Its high representation in many classic indicas makes it a reliable genetic marker when establishing or stabilizing cultivar families.
