Citral Breeding Lines

Citral is a monoterpene commonly found in cannabis cultivars with lemon, lime, and grapefruit aromatic profiles. This terpene occurs naturally in citrus plants and contributes to the distinctive fresh, bright character often associated with certain Haze and Sativa-dominant lineages. Citral-forward breeding lines have been developed through selective cultivation practices, with documented lineage records frequently reporting its presence in cultivars derived from Thai, Colombian, and Mexican landrace ancestry. The compound exists as two isomers—geranial and neral—which together define the citral phenotype. Breeders working in this category typically prioritize citral expression alongside other terpene profiles to maintain aromatic consistency across generations.

Breeders select for citral-dominant chemotypes to stabilize bright, citrus-forward aromatics in commercial and research lines. Citral expression is often paired with breeding objectives for terpene complexity and sensory differentiation in Sativa and hybrid development programs.
