Terpenes Overview

Terpenes are volatile organic compounds found in cannabis and many other plants, responsible for distinctive aromatic profiles. In cannabis genetics, over 150 identified terpenes contribute to the plant's sensory characteristics, though limonene, myrcene, pinene, and caryophyllene are among the most commonly documented in breeding records. Terpene expression is influenced by genetics, environmental conditions, harvesting timing, and post-harvest handling. Breeders and researchers study terpene profiles to understand strain lineage relationships and plant phenotype variation. Terpene composition varies significantly between individual plants, even within the same strain, due to both genotypic and phenotypic factors. Modern cannabis genetics documentation increasingly includes terpene data as a standard marker for strain characterization.

Cannabis breeders select parent plants partly on terpene expression and stability, as these compounds are heritable traits linked to specific genetic markers. Understanding terpene inheritance patterns helps breeders maintain or develop desired aromatic and flavor signatures across generations.
