Monoterpene Forward Selection

Monoterpene Forward Selection refers to breeding programs that prioritize cultivars expressing elevated levels of single terpenes—such as limonene, myrcene, or pinene—as primary aromatic and chemotype markers. Breeders employing this approach systematically select parent plants showing strong monoterpene dominance across generations, tracking terpene profiles via gas chromatography or sensory evaluation to stabilize desired profiles. This classification distinguishes itself from broader terpene-balanced breeding by its explicit focus on mono-dominant phenotypes rather than complex terpene blends. Common in commercial horticulture where consistency and recognizable aroma signatures drive market differentiation. The resulting cultivars often exhibit narrow terpene ranges, making them valuable reference genetics for studying monoterpene expression and environmental interaction.

Breeders use monoterpene forward selection to isolate stable, commercially repeatable aromatic profiles and to develop genetic lines suitable for both sensory consistency and potential industrial applications. This approach requires multi-generational phenotypic screening and controlled pollination to lock in monoterpene dominance without sacrificing vigor or yield.
