Olfactory Traits

Olfactory traits encompass the volatile chemical compounds—primarily terpenes and their combinations—that define a cannabis plant's aromatic profile. These traits are inherited through both parent genetics and environmental expression, making them valuable markers in breeding programs. Breeders document aroma families (citrus-forward, pine-dominant, floral, fuel-type, spice-noted) to track lineage consistency and predict offspring characteristics. Olfactory phenotypes often correlate with terpene ratios rather than single compounds, allowing breeders to stabilize or enhance specific scent families across generations. Understanding these traits requires controlled documentation, as aroma expression can shift with harvest timing, curing practices, and storage conditions.

Breeders select for olfactory consistency to maintain strain identity across seed production and to create predictable consumer-facing varieties. Tracking terpene-driven aroma families helps identify parent plants with desirable volatile profiles before chemical analysis, streamlining selection for stable line development.
