Myrcene Accumulation

Myrcene accumulation refers to cannabis cultivars that express notably high levels of the monoterpene myrcene in their volatile fraction. Myrcene is one of the most abundant terpenes across cannabis genetics and is commonly associated with herbal, earthy, and clove-like aromatic profiles. Breeders tracking this trait often observe it in indica-dominant lineages and landrace-derived genetics, though myrcene expression varies significantly across environments and harvest timing. Selection for high myrcene accumulation has been a foundational breeding target for decades, influencing the development of many contemporary cultivar families. Myrcene levels are influenced by genotype, light exposure, temperature, and phenotypic expression during flower maturation.

Breeders working in this category use myrcene accumulation as a phenotypic marker and selection criterion for creating stable cultivar lines with predictable aromatic profiles. High-myrcene genetics serve as parental stock in crosses aimed at stabilizing terpene expression and developing offspring with consistent volatile compound signatures.
