Apical Dominance Reduced
Apical dominance reduced (ADR) describes cannabis cultivars where the main central stem grows at a comparable rate to lateral branches, rather than significantly outpacing them. This trait results in a more bushier, horizontally-spreading plant architecture compared to tall, single-stem-focused phenotypes. ADR plants often exhibit multiple codominant colas of similar height and vigor. Breeders have selected for this trait in both photoperiod and autoflowering lines to maximize canopy spread and light interception in controlled environments. The genetic basis involves regulatory shifts in auxin distribution and apical meristem dominance, though specific loci remain incompletely characterized across breeding programs.

ADR genetics are valuable for indoor and greenhouse cultivation where horizontal space allows maximization of canopy density and light utilization. Breeders working in this category often combine ADR with vigor traits and uniform branching to achieve standardized, predictable plant structure across generations.
