Citral Genetics

Citral Genetics refers to cannabis cultivars selected or bred for elevated levels of citral, a monoterpene compound commonly associated with lemon, lime, and citrus aromatics. Citral itself comprises two isomers—geranial and neral—both volatile at room temperature and prominent in cultivars descended from citrus-forward parents like Lemon Haze, Super Lemon Haze, and various Thai landrace crosses. Lineage records frequently report citral dominance in sativa-leaning and hybrid material, particularly when limonene co-occurs. Breeders working in this category often stabilize citral expression through repeated selection of aromatic phenotypes across generations. The trait is valued in breeding programs for its sensory distinctiveness and consistency across related cultivars.

Breeders isolate and maintain citral-heavy lines by phenotypic selection during flowering and curing, using aroma as a primary screening tool. Crossing known citral-dominant parents and backcrossing to retain the trait are standard practices in commercial and artisanal seed production.
