Limonene Genetics

Limonene is a monocyclic monoterpene frequently observed in cannabis cultivars, particularly those descended from Citrus-adjacent landrace genetics and modern Sativa-leaning lineages. In cannabis breeding records, limonene accumulation often correlates with specific chemotype expressions and environmental growing conditions rather than single-gene determination. Breeders working with limonene-forward strains typically trace lineage through cultivars like Lemon Haze, Super Lemon Haze, and various Diesel-family crosses where citrus aromatics are documented traits. Limonene concentration can vary significantly between phenotypes within the same genetic line, suggesting polygenic and epigenetic factors influence expression. Understanding limonene genetics remains relevant for breeders seeking to stabilize citrus-forward aromatic profiles across successive generations.

Cannabis breeders select for limonene-dominant chemotypes through phenotype screening and backcrossing programs targeting citrus aromatic expression. Limonene levels are commonly assessed via chromatography analysis to identify and stabilize desired aromatic profiles in new cultivar development.
