Limonene Phenotypes

Limonene phenotypes represent cannabis cultivars where the terpene limonene contributes notably to the aromatic profile, often producing citrus-forward scents ranging from lemon to grapefruit to orange notes. Limonene is a naturally occurring compound found across many plant families and is commonly associated with citrus fruits. In cannabis breeding, limonene-dominant phenotypes emerge from genetic lines where this terpene accumulates at measurable levels during flower development. The expression of limonene varies based on cultivar genetics, growing conditions, harvest timing, and post-harvest handling. Lineage records frequently report limonene phenotypes arising from strains like Lemon Haze, Tangie, and their crosses, though terpene profiles can shift significantly across environmental contexts.

Breeders working in this category often select for limonene expression to develop cultivars with consistent citrus aromatics, as this terpene is relatively stable in many genetic backgrounds. Stabilizing limonene phenotypes requires multi-generational selection and environmental controls, since terpene ratios shift based on temperature, light spectrum, and nutrient timing during cultivation.
