Leaf Blade Width Wide

Wide leaf blade width refers to cannabis plants exhibiting notably broader leaflets relative to their length, typically measured across the widest point of individual fan leaves. This classification encompasses plants where the leaf-to-petiole ratio skews toward lateral expansion rather than elongation. Wide-bladed phenotypes are often associated with indica-dominant lineages and equatorial or subtropical breeding populations, though expression varies within strains. Breeders tracking this trait note correlations with plant structure, internodal spacing, and overall canopy density. The trait persists across generations when selected, making it a useful marker in breeding programs focused on specific growth architectures.

Breeders working with wide leaf blade genetics often prioritize this trait when selecting for compact plant structure, rapid canopy fill, or indica-type morphologies. Wide leaflets can influence light interception patterns and air circulation within dense canopies, making the trait relevant to cultivation-focused breeding objectives.
