Phenotype Testing
Phenotype testing is the systematic observation and documentation of observable plant characteristics across a cannabis grow cycle, including morphology, growth rate, flowering time, and sensory attributes like aroma and resin production. Breeders use phenotype testing to identify which plants express desired traits within a seed population, since seeds from the same cross often produce phenotypically distinct individuals. This practice is foundational to selective breeding programs, allowing cultivators to isolate stable expressions of parent genetics and make informed decisions about which individuals to preserve or cull. Phenotype testing relies on controlled environmental conditions to distinguish genetic expression from environmental influence, a critical distinction in breeding work. Documentation of phenotype data across multiple generations helps breeders build reliable profiles

Phenotype testing is essential for seed line development and F1 stability assessment. Breeders compare phenotypic data across generations to identify consistent trait expression and select breeding stock that will produce uniform offspring, directly informing decisions about line stabilization and IBL (inbred line) work.
