Flavor Genetics

Flavor genetics refers to the heritable terpene and phenolic profiles that define a strain's aromatic and taste characteristics. These compounds—primarily monoterpenes and sesquiterpenes—are controlled by multiple genes inherited from parent plants, creating distinct chemical signatures across cultivars. Breeders track flavor profiles through selective crosses, as terpene expression can vary significantly based on genetics, growing conditions, and harvest timing. Understanding flavor genetics helps breeders stabilize desirable aromatic traits across generations. Common flavor descriptors in cannabis breeding include citrus, pine, floral, fuel, and earthy notes, each tied to specific terpene combinations. Documentation of flavor stability is critical for maintaining strain integrity in seed production.

Breeders use flavor genetics as a key phenotypic marker when selecting parent plants and evaluating F1 and stabilized lines. Consistent terpene profiles across a cultivar require identifying and fixing the genetic loci responsible for dominant aromatic compounds, often through multi-generational selection and test crosses.
