Structure Phenotypes

Structure phenotypes describe the observable physical characteristics that emerge from a cannabis plant's genetic expression, including height, branching patterns, leaf morphology, and internodal spacing. These traits are foundational to breeding programs because they directly influence cultivation feasibility, yield potential, and cannabinoid/terpene expression across different environments. Breeders document structure phenotypes meticulously—tall versus compact growth, open versus dense canopy architecture, and leaf-to-flower ratios—as reproducible markers within strain families. Phenotypic variation within a single genotype can occur due to environmental factors like light, temperature, and nutrient availability, but stable structural traits are prioritized in stabilized cultivars. Understanding structure phenotypes is essential for matching plants to specific growing systems, from ho

Breeders select for structural traits to create cultivars suited to particular cultivation methods and climate zones. Stabilized structure phenotypes become defining characteristics of established strain lines and are documented in parentage records.
