Limonene Dominant Genetics

Limonene-dominant genetics refer to cannabis cultivars where limonene comprises the primary terpene profile, often constituting 30-60% of total terpene content. This monoterpene is commonly associated with citrus aromatics—lemon, lime, and grapefruit notes—and appears frequently in both indica and sativa lineages. Limonene biosynthesis is influenced by genetic markers affecting terpene synthase enzyme expression, making it a heritable trait across generations. Breeders working in this category often select parent plants showing consistent limonene peaks via gas chromatography analysis. Strains tagged as limonene-dominant include well-documented cultivars with established growing records and stable terpene expression across multiple harvests.

Cannabis breeders target limonene dominance through selective crosses of limonene-rich cultivars, tracking terpene ratios across F1, F2, and backcross generations. Limonene expression can vary with cultivation conditions (temperature, light spectrum, harvest timing), so breeding programs often stabilize this trait by identifying and propagating phenotypes showing reliable limonene elevation under
