Single Leader Phenotype
Single leader phenotype describes cannabis plants exhibiting a dominant central stem with minimal lateral branching, creating a columnar or Christmas tree-like structure. This growth pattern is often observed in sativa-dominant genetics and some pure indica lines, though expression varies significantly within seed populations. The trait appears influenced by both genetic predisposition and environmental factors including light quality, spacing, and nutrient availability. Single leader plants typically allocate resources toward vertical growth rather than horizontal canopy expansion, affecting cultivation strategy and yield distribution across the plant architecture.

The trait appears influenced by both genetic predisposition and environmental factors including light quality, spacing, and nutrient availability. Single leader plants typically allocate resources toward vertical growth rather than horizontal canopy expansion, affecting cultivation strategy and yield distribution across the plant architecture.
Breeders working with single leader phenotypes often select for this trait when developing strains intended for specific growing environments—particularly vertical gardens, space-limited operations, or breeding programs targeting upright plant architecture. Stabilizing single leader expression across seed generations requires consistent phenotypic selection and understanding of the genetic factors
