Testa Coloration
Testa coloration refers to the pigmentation of cannabis seed coats, ranging from black and dark brown to lighter tan and mottled patterns. Seed coat color is determined by genetic factors and environmental conditions during seed maturation, with darker testas often associated with fully mature, viable seeds. Breeders frequently observe that testa patterns can indicate seed development stage and viability, though coloration alone is not a definitive quality marker. Historical seed banking practices have relied on visual testa assessment as a preliminary screening tool. The genetics governing seed coat pigmentation remain incompletely characterized but appear linked to anthocyanin and melanin production in the seed integument.

Breeders working with seed production monitor testa coloration as a phenotypic indicator of seed ripeness and germination potential. Consistent seed coat appearance within a stable line can serve as a visual quality-control reference during breeding selection cycles.
