Genetic Pigmentation

Genetic pigmentation in cannabis refers to the hereditary expression of anthocyanins, carotenoids, and chlorophyll—compounds that produce the plant's visible coloration. These pigments are controlled by recessive and dominant alleles, making color a traceable trait through breeding generations. Purple, red, blue, and yellow hues are often tagged as pigmentation phenotypes, though environmental factors like temperature can influence final expression. Lineage records frequently report pigmentation stability across F1, F2, and backcross generations when parents carry consistent genetic markers. Understanding pigmentation inheritance helps breeders select for visual consistency and develop stable cultivars within specific color families.

Breeders working in ornamental and specialty markets actively select for pigmentation traits to establish recognizable visual identities. Pigmentation markers also serve as rough indicators of genetic stability and can correlate with terpene and cannabinoid profiles in some lineages, though direct causation remains unproven.
