Cultivar Classification

Cultivar classification systems organize cannabis genetics into broader categories based on cannabinoid ratios, terpene profiles, and historical breeding lineages. Common frameworks include Sativa-dominant, Indica-dominant, and Hybrid classifications, though these terms reflect breeding patterns rather than strict botanical taxonomy. Modern classification increasingly incorporates chemotype data (THC:CBD ratios) and terpene signatures to provide more precise genetic categorization. Breeders and seed banks use cultivar classification to communicate expected plant structure, growth patterns, and chemical profiles to other professionals in the breeding community. These classifications help establish baseline expectations for phenotypic expression across seed lots and breeding populations.

Cultivar classification serves as shorthand in breeding programs, allowing geneticists to predict growth characteristics, flowering times, and cannabinoid expression patterns when crossing parent plants. Classification systems help breeders organize germplasm libraries and document lineage relationships across generations.
