Phenotype Recording

Phenotype Recording refers to the systematic documentation of observable plant characteristics across cannabis cultivars—leaf morphology, flowering time, cannabinoid/terpene profiles, height, branch structure, and environmental responses. This practice is foundational to cannabis genetics work, enabling breeders to track trait expression across generations and environments. Detailed phenotype records create a baseline for understanding how genotypes manifest under different conditions, which is critical for reproducibility and strain stability. Phenotype Recording differs from genotyping (DNA analysis) but complements it; together they form the basis of modern breeding programs. Many seed banks and cultivators maintain phenotype databases to document commercial cultivars, though standardization of recording methods remains inconsistent across the industry.

Breeders rely on consistent phenotype recording to identify stable traits worth preserving, to detect phenotypic drift in seed lines, and to select parent plants for crosses. Accurate records allow breeders to predict offspring characteristics and to document which phenotypes emerge under specific growing conditions.
