Pigmentation Traits

Pigmentation traits in cannabis refer to the genetic expression of anthocyanins, carotenoids, and chlorophyll variations that produce visible color in flowers, leaves, and stems. These water-soluble and fat-soluble pigments are inherited through polygenic traits influenced by temperature, light exposure, pH levels, and genetic background. Purple, red, orange, and yellow hues are commonly associated with specific pigment compounds rather than with cannabinoid or terpene profiles, though breeders have historically selected for visual expression alongside other characteristics. Pigmentation traits are often tracked in breeding programs as phenotypic markers to maintain lineage consistency and cultivar identity. Understanding these traits is valuable for seed selection and crop documentation, though pigment presence does not indicate potency or flavor profile.

Breeders document pigmentation traits as stable phenotypic markers for cultivar verification and parent selection in controlled crosses. Pigmentation stability across generations helps breeders maintain visual consistency in commercial and preservation lines.
