Structure Dominant Traits

Structure Dominant Traits refer to heritable characteristics that control plant morphology, branching pattern, stem thickness, and overall architecture in cannabis cultivars. These traits are often polygenic, influenced by multiple loci, and shaped by both nuclear and cytoplasmic inheritance. Breeders classify plants along a spectrum from compact, bushy phenotypes (heavy branching, short internodes) to tall, sparse architectures (extended internodes, reduced lateral growth). Environmental conditions—light intensity, photoperiod, nutrient availability—interact substantially with genetic potential, making structure a complex breeding target. Understanding structure dominance helps predictors anticipate canopy density, light penetration requirements, and yield distribution across plant zones.

Breeders select for structure dominant traits to optimize cultivation systems (indoor SOG vs. outdoor sprawl), manage canopy management labor, and improve light exposure to lower flower sites. Structure-focused selection also influences feeding schedules and training response, making it a primary consideration in cultivar development for commercial and craft producers.
