Seed Coat Color

Seed coat color refers to the external pigmentation of cannabis seeds, typically ranging from dark brown or black to lighter tan or striped patterns. This visible trait is determined by genetic factors inherited from parent plants and can serve as a basic phenotypic marker during seed selection and storage. Seed coat coloration does not directly indicate viability or genetic potential, though breeders often track coat color consistency as part of strain documentation. Environmental factors during seed maturation may influence final coat appearance, making visual assessment one of several evaluation methods. Proper seed coat integrity—regardless of color—protects the embryo during storage and germination. Detailed seed photography and color notation have become standard practice in professional breeding records.

Breeders monitor seed coat color as a simple visual indicator of seed maturity and strain consistency across generations. Tracking coat color patterns within a cross can help identify genetic segregation and distinguish seed batches in large-scale breeding programs.
