Pigment Phenotypes

Pigment phenotypes refer to the visible color expressions in cannabis plants, determined by the presence and concentration of anthocyanins, carotenoids, and chlorophyll. These compounds develop in response to genetics, environmental stressors (temperature, light exposure, nutrient availability), and plant maturity. Breeders and cultivators track pigment expression as a heritable trait, though the same genotype can display different colors under varying conditions. Documentation of pigment phenotypes helps distinguish cultivars and supports breeding programs aiming for specific visual characteristics. Common pigment expressions include deep purples, blues, reds, oranges, and yellows, each linked to different chemical profiles. Understanding pigment inheritance is essential for both genetic preservation and predictable crop planning.

Breeders select for stable pigment phenotypes when developing new cultivars, using color consistency as a marker for genetic stability and environmental resilience. Pigment traits are often tracked across generations to identify which genetic backgrounds reliably express desired color profiles.
