Beta Myrcene

Beta-myrcene is a monoterpene commonly detected in cannabis cultivars, particularly those with Indica-leaning genetics or OG and Skunk lineage backgrounds. The compound is also prevalent in hops, lemongrass, and thyme, contributing to herbal and earthy sensory profiles in cannabis flower. Lineage records frequently report beta-myrcene as a dominant terpene in strains descended from Thai, Afghan, and Jamaican landrace genetics. Breeders monitoring terpene profiles often associate elevated beta-myrcene expression with certain phenotypes within Kush and Diesel families, though environmental factors significantly influence final terpene composition.

Breeders working in preserved or hybrid lines frequently select for beta-myrcene retention as a marker of traditional chemotype expression. Terpene profiling has become a standard breeding tool for maintaining or modifying this trait across generations.
