Female Phenotype

Female phenotype refers to cannabis plants that develop reproductive structures characteristic of the female sex, including pistils and calyx tissue. In dioecious cannabis populations, female plants are distinguished by their ability to produce flowers with stigmas (hair-like structures) and seed-bearing calyces when pollinated. This classification is foundational to breeding programs, as female plants are the primary source of cannabinoid-rich flower material and the seed-bearing parent in controlled crosses. Phenotypic sex expression can be influenced by genetic factors and environmental conditions, though genetic predisposition remains the primary determinant. Female phenotypes are central to both seed production (when crossed with males) and clonal propagation strategies in commercial and research settings.

Breeders select female phenotypes as maternal parents in deliberate crosses to create hybrid offspring with desired trait combinations. Understanding consistent female expression is critical for feminized seed development and maintaining stable breeding lines.
