Pigment Inheritance

Pigment inheritance refers to the genetic transmission of anthocyanins, carotenoids, and chlorophyll-related compounds that produce visible coloration in cannabis plants—ranging from deep purples and blues to reds and oranges. These pigments are polygenic traits, meaning multiple genes control their expression, and they are influenced by both genotype and environmental factors like temperature and light exposure. Breeders track pigment inheritance patterns across generations to stabilize color phenotypes in cultivar development. Understanding pigment genetics helps distinguish true genetic color expression from environmentally induced coloration, which is relevant for breeding programs focused on consistent visual markers. Pigment compounds are distinct from cannabinoids and terpenes, though they may co-segregate with desirable chemotypes in certain lineages.

Breeders use pigment inheritance as a secondary selection marker to track lineage consistency and stabilize color-stable strains. Stable pigmentation can serve as a visual phenotypic identifier across generations, aiding in cultivar recognition and quality control in seed production.
