Morphology Traits

Morphology traits refer to the observable structural and physical characteristics of cannabis plants, including height, branching pattern, leaf shape, internode spacing, and overall architecture. Breeders and cultivators document these traits to predict growth behavior, optimize space efficiency, and maintain consistency across generations. Morphological features are influenced by both genetics and environmental conditions, making them critical markers for breeding selection and cultivation planning. Understanding morphology helps distinguish between indica-dominant, sativa-dominant, and hybrid expressions, though these categories reflect tendency rather than absolute plant structure. Seed banks and breeders frequently record morphological data to help growers anticipate plant development across different growing systems.

Breeders select for specific morphological traits to develop plants suited to particular cultivation methods—compact growth for indoor production, vigorous branching for outdoor yields, or specific leaf-to-calyx ratios for processing. Consistent morphology across a line signals genetic stability and predictability, making it a foundational quality metric in breeding programs.
