Myrcene Cannabis Breeding

Myrcene is one of the most prevalent monoterpenes in cannabis, frequently comprising 20–65% of a strain's total terpene profile. This compound is commonly associated with earthy, herbal, and sometimes fruity or clove-like aromatic notes. Myrcene appears across diverse genetic backgrounds—from classic indica landraces to modern hybrid cultivars—making it a foundational marker in cannabis chemotyping. Breeders and geneticists track myrcene levels as both a phenotypic descriptor and a potential modifier of plant maturation patterns. Understanding myrcene distribution in lineage records helps establish breeding strategies for aroma stability and terpene consistency across generations.

Breeders working in high-myrcene categories often select parent plants based on terpene lab results and organoleptic assessment to maintain or amplify earthy/herbal profiles in offspring. Myrcene levels can vary significantly within a single genetic line depending on cultivation conditions, harvest timing, and curing practices, so lineage documentation helps breeders predict expression ranges.
