Wide Leaflet

Wide Leaflet refers to cannabis plants expressing broader, more expansive leaf structures compared to narrow-leaflet phenotypes. This trait is commonly associated with indica-dominant genetics, where wider leaves are often tagged as an adaptation marker in breeding records. The distinction between wide and narrow leaflets has been used historically by cultivators and breeders to make preliminary phenotype assessments, though leaf morphology alone does not reliably predict cannabinoid or terpene profiles. Lineage records frequently report wide-leaflet expression in plants with Central Asian and Hindu Kush ancestry. Modern cultivation focuses less on leaf width as a primary selection criterion and more on yield, potency stability, and environmental resilience.

Breeders working with wide-leaflet traits often observe correlations with shorter flowering times and denser plant structures, making this phenotype useful for line stabilization and hybrid development. Selection for or against wide leaflets is typically secondary to cannabinoid and terpene profiling in contemporary breeding programs.
