Terpene Loci

Terpene loci refers to the chromosomal locations where genes encoding terpene synthases and related biosynthetic enzymes are positioned within the cannabis genome. These genetic regions control the production of volatile aromatic compounds, with multiple loci working together to determine a plant's terpene profile. Research into terpene loci has expanded understanding of how cannabinoid-producing plants regulate their secondary metabolism. Breeders studying terpene inheritance patterns reference these genomic regions when tracking the heritability of aromatic traits across generations. Mapping terpene loci remains an active area of cannabis genetics research, with implications for cultivar stability and trait predictability.

Breeders use terpene loci mapping to identify which genetic markers correlate with specific aromatic profiles, enabling more targeted selection for consistent flavor and aroma expression. Understanding these chromosomal positions helps explain why some lineages reliably produce dominant terpene combinations while others show high phenotypic variation.
