Myrcene Bearing Lines

Myrcene-bearing lines represent a broad category of cannabis genetics selected or bred for elevated myrcene terpene expression. Myrcene is the most abundant terpene in many modern cultivars and is commonly associated with herbal, earthy, and musky aromatic profiles. These genetics span multiple foundational families and are not a discrete lineage but rather a functional classification applied across Indica-dominant, hybrid, and some Sativa-leaning strains. Breeders working in this category often prioritize myrcene prominence to develop cultivars with consistent sensory characteristics. Preservation of myrcene-rich genetics has become standard practice in seed banking and clone libraries, as myrcene expression is valued across both commercial and craft breeding programs.

Myrcene levels are heritable and responsive to selection; breeders cross myrcene-dominant parents to reinforce the trait across generations. Understanding myrcene phenotypes helps breeders predict aromatic outcomes and combine this terpene with other desirable traits like plant structure or flowering time.
