Chocolate Phenotype

Chocolate phenotype refers to cannabis plants expressing darker brown or deep mahogany coloration in flowers, leaves, or both—a visible trait distinct from typical green growth. This coloration arises from anthocyanin and other pigment expression influenced by genetics, temperature stress, and nutrient availability during flowering. Lineage records frequently report chocolate phenotypes in strains descended from landrace populations and modern F1 hybrids bred for pigment stability. Breeders distinguish chocolate phenotypes by visual inspection at harvest, though the trait's expression varies by environmental conditions and genetic background. This classification is purely morphological and relates to plant structure rather than cannabinoid or terpene content.

Breeders working in this category often select for consistent brown pigmentation as a stable marker trait, useful for phenotype identification and breeding documentation. Chocolate coloration has become a minor selection criterion in some commercial breeding programs seeking visual differentiation, though it does not inherently affect cannabinoid potency or composition.
