Myrcene Notes

Myrcene is one of the most abundant terpenes found across cannabis varieties, often comprising 20–65% of a strain's terpene profile. It is commonly associated with herbal, earthy, and clove-like aromatic characteristics, though myrcene-dominant plants may also present piney or fruity undertones depending on co-occurring terpenes. Myrcene occurs naturally in hops, mangoes, and lemongrass, making it a recognizable compound in plant chemistry. In cannabis breeding, myrcene prevalence is frequently documented across both indica and sativa lineages, though certain ancestral lines—particularly those derived from landrace populations—show consistently elevated myrcene content. Breeders often track myrcene levels as a baseline marker when characterizing strain families and establishing terpene profiles for new crosses.

Breeders monitor myrcene concentration as a foundational terpene metric because of its prevalence across diverse genetic backgrounds and its stability across growing conditions. Understanding myrcene-dominant versus myrcene-minor phenotypes helps breeders predict aromatic outcomes and maintain consistency in targeted strain development.
