Leaf Blade Count
Leaf blade count refers to the number of leaflets on a cannabis plant's fan leaves, typically ranging from 5 to 13 blades per leaf. This morphological trait is inherited and varies significantly across different strain lineages and regional genetics. Breeders working in this category have observed that sativa-dominant cultivars often express higher blade counts (9–13), while indica-dominant plants frequently display lower counts (5–7). Leaf blade count influences photosynthetic surface area and can affect plant vigor during vegetative growth. The trait remains relatively stable within established seed lines, making it a useful marker for lineage identification and phenotype selection.

Breeders monitor leaf blade count as a secondary morphological trait to confirm genetic lineage stability and select for desired growth characteristics. Higher blade-count phenotypes are often associated with extended vegetative vigor, while lower counts may correlate with earlier flowering phases.
