Serrated Edges

Serrated edges refer to the distinctive saw-tooth or jagged margin pattern along cannabis leaf borders, contrasting with smooth-edged leaves. This trait appears on both fan leaves and sugar leaves, with variation in tooth depth and frequency across cultivars. Serrated morphology is commonly observed across diverse genetic backgrounds and does not correlate strongly with cannabinoid or terpene profiles. The trait is largely determined by polygenic inheritance, making it an unreliable single-marker for strain identification. Breeders document leaf morphology as part of phenotype cataloging, though serrated versus smooth edges carries minimal practical breeding weight compared to flowering time or yield architecture.

Leaf margin patterns are tracked during phenotype documentation and preservation work, helping breeders maintain detailed morphological records within seed lines. However, serration depth is a low-priority selection criterion in most breeding programs, as it does not affect plant vigor, cannabinoid synthesis, or cultivation outcomes.
