Flavonoid Pathways

Flavonoid pathways represent the biochemical processes through which cannabis plants synthesize flavonoids—a diverse class of polyphenolic compounds responsible for pigmentation, UV protection, and aromatic characteristics. In cannabis genetics, flavonoid expression varies significantly across cultivars, influenced by both genetic background and environmental conditions such as light exposure and temperature. Breeders tracking flavonoid pathways observe correlations with visible traits like leaf anthocyanins (purples and reds), resin coloration, and certain aromatic notes. These compounds are distinct from cannabinoids and terpenes but interact within the plant's overall phytochemistry. Understanding flavonoid genetics remains an active area of cannabis breeding research, particularly as growers seek stable color expression and novel aromatic profiles. Lineage records frequently report f

Cannabis breeders use flavonoid pathway selection to stabilize visual phenotypes—particularly purple, red, and blue pigmentation in leaves and flowers—and to identify plants with distinctive aromatic secondary compounds. Flavonoid trait stability across generations helps breeders create reliably colorful cultivars for both aesthetic consistency and potential marker-assisted selection programs.
