Citral Terpene Chemistry

Citral is a naturally occurring monoterpene found in cannabis and many other plants, consisting primarily of geranial and neral isomers. In cannabis breeding contexts, citral contribution to aroma profiles is often associated with lemon, lime, and herbal notes. Lineage records frequently report citral prominence in certain landrace populations and modern cultivars descended from Citral-rich parentage. The terpene's chemical structure and volatility influence both fresh aroma expression and how profiles shift during drying and curing. Understanding citral chemistry helps breeders select for stable, predictable aroma phenotypes across generations.

Breeders working with citral-forward genetics often track this terpene's stability through cultivation and storage, as its volatile nature affects finished product consistency. Citral expression is commonly used as a marker trait when developing cultivars with specific sensory profiles or when crossing lines for aroma trait amplification.
