Structure Phenotypes

Structure phenotypes refer to the observable plant architecture and growth patterns that emerge from cannabis genetics, independent of cannabinoid or terpene profiles. These include traits like internode spacing, branching patterns, leaf size, stem thickness, and overall height potential—characteristics that are largely determined by polygenic inheritance and environmental interaction. Breeders have long selected for specific structural traits to optimize cultivation efficiency, yield potential, and canopy management across different growing environments. Common structural categories include compact/bushy phenotypes (shorter internodes, dense branching) and tall/stretchy phenotypes (longer internodes, open structure). Understanding structure phenotypes is critical for growers matching genetics to their space constraints, and for breeders developing cultivars suited to particular producti

Breeders actively select for structure phenotypes to create cultivars tailored to specific growing methods and facility constraints. Consistent structural traits improve predictability in yield planning, canopy management, and labor efficiency across commercial production scales.
