Cultivar Morphology

Cultivar morphology refers to the observable physical structure and growth characteristics of cannabis plants, including height, branching patterns, leaf shape, and bud density. Breeders systematically document morphological traits to classify lines, predict yield potential, and identify plants suited to specific growing environments. These structural features are influenced by both genetics and environmental conditions, making morphology a key tool in breeding programs and cultivation planning. Understanding cultivar morphology helps breeders select parents for consistent offspring characteristics and growers optimize canopy management. Morphological documentation across generations creates the foundation for stable, repeatable strain families.

Breeders track morphological traits—such as internode spacing, branch angle, and flower site density—as heritable markers for parent selection and offspring prediction. Stable morphological expression across generations indicates genetic consistency and is essential for cultivar registration and seed production.
