Phenotypic Documentation

Phenotypic documentation refers to the systematic recording of observable plant traits—morphology, flowering time, leaf structure, resin production, and aroma profile—across cannabis seed batches and generations. Breeders maintain detailed phenotypic records to track genetic stability, identify keeper phenotypes, and predict offspring performance. This practice is foundational to reproducible breeding programs and helps distinguish between genetic potential and environmental expression. Documentation typically includes photographs, growth metrics, terpene profiles, and cannabinoid data collected under controlled conditions. Accurate phenotypic records enable breeders to select for consistency, stability, and desired traits across multiple grow cycles.

Systematic phenotypic documentation allows breeders to identify the most stable and predictable plant expressions within a line, establish breeding standards, and make informed selection decisions. Without detailed records, breeders cannot reliably replicate results or communicate expectations to seed producers and growers.
