Terpene Myrcene Dominant

Myrcene-dominant cannabis strains are characterized by elevated levels of the monoterpene myrcene, which frequently comprises 20–65% of a strain's terpene profile. Myrcene is one of the most abundant terpenes in cannabis and is also found in hops, mangoes, and lemongrass. Lineage records and breeding documentation commonly associate myrcene-dominant varieties with earthy, herbal, and sometimes fruity or peppery aromatic notes. Breeders working in this category often select parent plants showing high myrcene expression to stabilize these chemical profiles across generations. Understanding myrcene distribution is relevant to genetic preservation efforts and strain classification work, particularly when tracking terpene inheritance across hybrid crosses.

Breeders use myrcene-dominant parent selection to establish consistent aromatic signatures and to study how terpene expression responds to environmental factors and genetic backgrounds. Myrcene levels and ratios relative to other terpenes (limonene, pinene, caryophyllene) are tracked in breeding programs to document strain identity and maintain biochemical consistency.
