Terpene Expression Markers

Terpene expression markers refer to genetic and environmental indicators that correlate with volatile organic compound (VOC) production profiles in cannabis. These markers help breeders identify and select plants likely to develop specific aromatic compounds—such as limonene, myrcene, or pinene—across generations. Expression markers operate at both the genotypic level (underlying genetic sequences) and phenotypic level (observable aromatic output), influenced by cultivation conditions, harvest timing, and post-harvest handling. Understanding these markers enables more predictable breeding outcomes and helps preserve aromatic diversity across strain families. Research into terpene expression remains an active area in cannabis genetics documentation and breeding program design.

Breeders use terpene expression markers to select parent plants with stable, heritable aromatic profiles and to predict offspring VOC composition with greater accuracy. Marker-assisted selection accelerates the development of strains with consistent sensory characteristics across multiple generations.
