Strain Characterization

Strain characterization refers to the systematic identification and documentation of a cannabis cultivar's genetic, phenotypic, and chemical markers. This practice involves analyzing cannabinoid profiles, terpene compositions, morphological traits, and growth patterns to distinguish one strain from another. Accurate characterization is foundational to breeding programs, seed banking, and maintaining genetic integrity across generations. Breeders and researchers use standardized testing methods—including gas chromatography and DNA analysis—to create reliable strain records. Proper characterization prevents genetic drift, enables reproducible cultivation practices, and supports informed breeding decisions within the cannabis genetics community.

Breeders rely on strain characterization to select parent plants for crosses, verify F1 hybrid stability, and identify recessive traits worth stabilizing. Detailed phenotypic and chemical records allow breeders to predict offspring traits and maintain consistency within a named cultivar across multiple generations.
