Terpene Limonene

Limonene is a monocyclic monoterpene commonly identified in cannabis cultivars, though it appears in higher concentrations in citrus fruits and some herbal plants. In cannabis genetics, limonene presence is often associated with bright, citrusy aromatic profiles—ranging from lemon and lime notes to grapefruit-like character. Lineage records frequently report limonene as a secondary or primary terpene in strains derived from sativa-dominant or hybrid ancestry. The compound's detection in laboratory analysis depends on cultivation conditions, harvest timing, and post-harvest handling, making terpene profiles variable across identical genotypes. Breeders working in this category often track limonene expression as a phenotypic marker when selecting parent plants for aroma stabilization across generations.

Breeders use limonene-forward phenotypes as genetic markers in selective breeding programs, particularly when targeting consistency in aromatic expression. Monitoring limonene levels during controlled crosses helps establish stable terpene profiles in new cultivar lines.
