Pigment Inheritance

Pigment inheritance in cannabis describes how anthocyanins, carotenoids, and chlorophyll expression is passed from parent plants to offspring. These water- and fat-soluble compounds produce the purple, red, orange, and yellow hues observed in leaves, bracts, and trichomes during growth and senescence. Pigment expression is controlled by multiple genes and is heavily influenced by temperature, light exposure, and nutrient availability, making phenotypic color outcomes variable even within stable genetic lines. Understanding pigment inheritance patterns helps breeders select for consistent coloration traits across generations. Documentation of pigment genes remains limited compared to cannabinoid and terpene research, though breeding records increasingly track anthocyanin-dominant and carotenoid-rich lineages.

Breeders working in ornamental and commercial cultivar development often select for stable pigmentation to differentiate cultivars visually and maintain market identity. Pigment inheritance knowledge supports multi-generational stabilization of color-fixed phenotypes in F2 and IBL populations.
