Myrcene Phenotypes

Myrcene phenotypes represent cannabis plants expressing elevated levels of the monoterpene myrcene, a terpene commonly associated with earthy, herbal, and fruity aromatic profiles. Myrcene is the most abundant terpene in many cannabis varieties and is also found in hops, lemongrass, and mango. Plants displaying myrcene-dominant phenotypes often show genetic lineage traceable to foundational landrace strains and modern cultivars bred for terpene stability. Myrcene content can vary significantly across phenotypes within a single strain family due to environmental factors, growing conditions, and individual plant expression. Breeders working in this category typically assess myrcene levels through chromatographic testing to maintain consistency across seed generations and crosses.

Myrcene phenotypes serve as reliable genetic markers for breeders selecting parent plants with stable terpene profiles. Many modern hybrid programs intentionally incorporate myrcene-rich genetics to achieve predictable aromatic outcomes across large seed populations.
