High Myrcene Cultivars

High myrcene cultivars are cannabis varieties in which myrcene—a monoterpene—comprises a substantial portion of the total terpene profile, often reported at 0.5% or higher of plant material by weight. Myrcene is commonly associated with earthy, herbal, and fruity aromatic notes, and appears across diverse genetic backgrounds including both indica and sativa lineages. Lineage records frequently report myrcene-dominant chemotypes emerging from classic cultivars like Skunk #1, Afghan landrace genetics, and various OG-family selections. Breeders working in this category often select parent plants through gas chromatography or mass spectrometry analysis to establish stable myrcene-forward expression across generations. The trait's prevalence in commercial cultivars reflects both its sensory prominence and its role in broader terpene-cannabinoid combinations that inform breeding goals.

Breeders targeting high-myrcene phenotypes typically screen parental stock via terpene profiling before crossing, aiming to stabilize dominant myrcene loci while managing other volatile compounds. Myrcene's prevalence across unrelated genetic lines suggests multiple genetic pathways control its biosynthesis, making it a useful marker for chemotype stability and predictability in multi-generation b
