Phenotype Observation
Phenotype observation refers to the documented visual, structural, and aromatic traits expressed by a cannabis plant during cultivation. Unlike genotype (the genetic code itself), phenotype represents the actual manifestation of genes under specific environmental conditions—leaf shape, plant height, flowering time, terpene profiles, and resin production patterns. Breeders meticulously record phenotypic variation within seed runs to identify stable lines and desirable trait combinations. Environmental factors like light, temperature, humidity, and soil composition significantly influence phenotypic expression, meaning identical genetics may display different characteristics across growing conditions. Accurate phenotype documentation forms the foundation of modern cannabis breeding work, enabling selection pressure toward reproducible cultivars.

Breeders rely on systematic phenotype observation to identify keeper plants, stabilize F1 crosses into consistent F2+ lines, and track trait heritability across generations. Detailed observation records allow breeders to distinguish environmental variation from true genetic expression, ensuring selection decisions produce reliable cultivar stability.
