Limonene Terpene Profile

Limonene is a monocyclic monoterpene commonly found across citrus species and cannabis cultivars, often associated with bright, zesty aromatic profiles. In cannabis breeding, limonene-dominant strains frequently appear in lineages descended from citrus-forward parent plants, particularly within Haze and Lemon-named cultivar families. Limonene biosynthesis occurs early in flower development and is influenced by temperature, light, and genetic predisposition. Breeders tracking this terpene use gas chromatography or headspace analysis to phenotype cultivars for consistency. Understanding limonene distribution helps breeders select parents for aroma-forward breeding programs and study terpene stability across generations.

Cultivators and breeders working in aroma-focused breeding programs often use limonene abundance as a selection marker for parent plants. Limonene expression can vary significantly between phenotypes of the same strain, making it a useful trait for isolating consistent, citrus-forward cultivars through multi-generational selection.
