Citral Genetics

Citral is a monoterpene comprising two isomers—geranial and neral—commonly associated with lemon and citrus aromatics in cannabis cultivars. Lineage records frequently report citral prominence in strains descended from Lemonade, Lemon Haze, and Citral-forward Thai landrace crosses. The terpene's presence is often correlated with specific environmental conditions during flowering, including temperature and light exposure, making it a trait of interest in controlled breeding programs. Citral-dominant chemotypes appear across multiple strain families and are not restricted to particular cannabinoid ratios, though documentation of consistent expression remains limited in peer-reviewed breeding literature.

Breeders working in citrus-forward phenotype selection monitor citral levels alongside limonene and myrcene profiles to stabilize aromatic consistency across generations. Citral genetics present challenges in preservation, as the terpene's volatile nature requires careful environmental management during cultivation and seed storage to maintain expression fidelity in offspring.
