Leaf Morphology Narrow
Narrow leaf morphology refers to cannabis plants displaying characteristically thin, elongated leaflets with reduced blade width relative to length. This trait is commonly associated with sativa-type genetics and certain highland landrace populations, where narrow leaves may reflect adaptation to specific environmental conditions. Breeders working in this category often note that narrow-leafed plants tend to exhibit different canopy architecture and light penetration patterns compared to broad-leafed counterparts. The trait is polygenic and influenced by both nuclear and potentially cytoplasmic factors, making it a useful marker in pedigree documentation and strain classification systems.

Narrow leaf morphology serves as a visual phenotypic marker in breeding programs, helping breeders track genetic lineage and identify sativa-dominant or specific regional landrace contributions. Selection for this trait intersects with plant structure, growth rate, and environmental adaptation goals in many contemporary breeding projects.
