Pigmentation Phenotype

Pigmentation phenotype refers to the visible color expressions in cannabis plants, ranging from greens and purples to reds and blacks, determined by the interplay of chlorophyll, anthocyanins, carotenoids, and environmental factors. These color variations are heritable traits influenced by multiple genes, though expression remains highly responsive to temperature, light spectrum, and nutrient availability during flowering. Breeders have selectively worked with pigmentation markers for decades, with darker and more vibrant cultivars becoming increasingly documented in lineage records. Purple and red pigmentations are commonly associated with anthocyanin production, while these compounds are distinct from cannabinoid or terpene profiles. Understanding pigmentation as a phenotypic trait helps breeders track genetic lineages and predict structural or resilience characteristics that may corre

Pigmentation serves as a visible genetic marker in breeding programs, allowing cultivators to identify and select plants carrying specific alleles. Breeders working with anthocyanin-rich genetics often track color stability across generations to establish true-breeding lines with consistent pigmentation expression.
