Myrcene Phenotypes

Myrcene phenotypes represent cannabis plants expressing elevated levels of the myrcene terpene, a monoterpene commonly found across the plant kingdom. In cannabis breeding records, myrcene-dominant phenotypes frequently emerge from Indica-leaning lineages and crosses involving classic landraces like Hindu Kush and Afghani varieties. These phenotypes are often tagged as displaying herbal, earthy, or clove-like aromatic profiles, though individual expression varies significantly based on growing conditions, harvest timing, and genetic background. Myrcene comprises a substantial percentage of total terpene content in many commercial cultivars, making it one of the most studied terpenes in cannabis genetics documentation. Breeders working in this category track myrcene ratios across generations to stabilize aromatic and growth-related traits associated with this terpene family.

Breeders selecting for myrcene phenotypes use gas chromatography and headspace analysis to identify and stabilize high-myrcene expression across generations. Understanding myrcene distribution helps breeders predict flowering characteristics, growth vigor, and flavor stability in hybrid crosses.
