Flower Color Genetics

Flower color in cannabis is controlled by anthocyanin and carotenoid pigment expression, regulated by multiple genetic loci and influenced by temperature, pH, and light conditions during flowering. Breeders have documented color phenotypes ranging from deep purple and black to red, pink, and yellow hues, often correlated with specific terpene profiles and plant ancestry. Color genetics follow complex inheritance patterns; purple coloration, for example, is commonly associated with cooler temperatures triggering anthocyanin production in genetically predisposed cultivars. Historical breeding records frequently report color selection as a secondary trait paired with cannabinoid or terpene targeting. Understanding flower color genetics helps breeders predict offspring phenotypes and maintain trait consistency across generations. Modern genetic mapping continues to identify specific genes in

Breeders use flower color as a visual marker for genetic stability and phenotype consistency, though color alone does not indicate cannabinoid or terpene content. Selecting for specific color traits requires maintaining environmental controls during flowering and tracking color expression across multiple generations to establish reliable breeding lines.
