Morphological Traits

Morphological traits refer to the observable physical characteristics of cannabis plants, including height, branching structure, leaf shape, and flowering patterns. These visible features are the primary basis for plant identification and classification within breeding programs. Breeders document morphological traits to standardize cultivars, predict growth behavior, and maintain genetic consistency across generations. Understanding morphology is essential for cultivation planning, as traits like internodal spacing and leaf-to-flower ratio directly influence yield potential and grow requirements. Morphological assessment occurs throughout a plant's lifecycle and forms the foundation for establishing stable phenotypes within seed lines.

Breeders select for specific morphological traits to develop cultivars suited to particular environments—compact structures for indoor cultivation, vigorous branching for sea-of-green systems, or distinctive leaf morphology for phenotype stability. Consistent documentation of morphological markers helps establish cultivar standards and enables reliable seed line maintenance.
