Pigmentation Genetics

Pigmentation genetics in cannabis refers to the inherited traits controlling anthocyanin and carotenoid production in plant tissues, resulting in purple, red, blue, and dark coloration patterns. These traits are polygenic, meaning multiple genes contribute to final phenotype expression, and environmental factors—particularly temperature and light exposure—significantly influence visible pigmentation. Lineage records frequently report pigmentation as a stable marker in certain family lines, though expression varies across growing conditions. Breeders working in this category often select for consistent color development as a secondary trait while maintaining primary cannabinoid and terpene profiles. Understanding pigmentation genetics helps distinguish between true genetic color expression and environmental stress responses. This classification is important for strain documentation and br

Pigmentation traits serve breeders as visual markers for lineage tracking and phenotype stability across generations. Selection for reliable color expression supports reproducibility in commercial cultivation and helps identify distinct cultivar identities within competitive markets.
