Limonene Breeding

Limonene is a monocyclic monoterpene commonly found in cannabis cultivars, often associated with citrus aromatics. Breeders working in this category have documented limonene expression across numerous genetic lineages, particularly in strains descended from Sativa-dominant and hybrid backgrounds. The terpene's presence is influenced by both genetic factors and environmental conditions during cultivation, making it a variable trait in breeding programs. Limonene production can be selected for through phenotype screening across multiple generations, though expression levels may shift depending on growing parameters. Understanding limonene's genetic basis helps breeders maintain consistent aromatic profiles when developing new cultivar lines.

Breeders selecting for limonene-forward phenotypes typically screen mature flowers and tissue samples for terpene profiles across F2 and F3 generations to identify stable expressers. Limonene is often paired with other terpenes in breeding goals to create specific aromatic and flavor signatures.
