Green Phenotype

Green phenotype refers to cannabis plants that express predominantly green coloration throughout their growth cycle, lacking the purple, red, or blue pigmentation seen in other phenotypic variants. This trait is controlled by recessive genetic expressions and environmental factors, particularly temperature exposure during flowering. Breeders working in this category often maintain green phenotypes as baseline genetics, since the absence of anthocyanin pigments is the default state in many foundational lineages. Green phenotypes are commonly associated with specific parent genetics rather than environmental stress, though cool temperatures can suppress color development. Understanding green phenotype expression helps breeders identify stable genetic backgrounds and predict offspring coloration in breeding projects.

Breeders use green phenotype lines as reliable genetic standards for stability testing and as parent material when colored phenotypes are not the selection target. Identifying consistently green offspring helps confirm expected Mendelian inheritance patterns in controlled crosses.
