Dominant Terpene Expression

Dominant terpene expression refers to the prominent aromatic compounds that characterize a cannabis strain's chemical profile. In breeding programs, certain terpenes consistently accumulate to higher concentrations than others, creating distinctive smell and flavor signatures. This occurs through selective breeding of parent plants exhibiting desired terpene profiles across generations. Dominant terpenes are often inherited as polygenetic traits, meaning multiple genes influence their production levels. Understanding which terpenes dominate in a strain helps breeders stabilize aromatic characteristics and document strain lineages. Terpene expression can vary based on environmental conditions, cultivation timing, and post-harvest handling, making consistent documentation across growing conditions valuable for breeding records.

Breeders select parent plants with measurable dominant terpene profiles to establish stable, recognizable strain characteristics. Tracking dominant terpenes across generations helps verify genetic stability and supports breeding decisions for creating new cultivar combinations.
