Terpene Dominance Selection

Terpene dominance selection refers to breeding practices where cultivators deliberately choose parent plants based on their terpene profiles, aiming to stabilize or amplify specific volatile compounds across generations. This approach is central to modern cannabis genetics work, as terpenes contribute significantly to aroma, flavor, and aromatic classification of cultivars. Breeders working in this category often phenotype plants during growth cycles, selecting individuals with notable terpene expression for breeding stock. Unlike cannabinoid-focused selection, terpene work requires repeated sensory and chemical evaluation across seed lines to identify consistent producers. This technique has become standard in stabilizing named strain families and developing predictable lineages.

Breeders use terpene dominance selection to maintain strain identity across crosses and backcrosses, ensuring that commercially recognized cultivars retain their characteristic aromatic signatures. Phenotypic stability in terpene production is especially valuable for seed-line consistency and for establishing mother plants in clonal programs.
