Pollen Sterility
Pollen sterility refers to a plant's inability to produce viable pollen capable of fertilizing female flowers. This trait can occur naturally due to genetic factors, chromosomal irregularities, or environmental stress, and is sometimes deliberately selected in breeding programs to prevent unwanted pollination. Plants exhibiting pollen sterility may still produce viable seeds if pollinated by external pollen sources, but cannot serve as male parents in controlled crosses. Breeders working in seedless fruit production and certain ornamental cannabis programs have documented interest in understanding pollen sterility mechanisms, though practical application remains limited in cannabis cultivation.

Pollen sterile cultivars are occasionally studied by breeders seeking to understand reproductive genetics and prevent accidental pollination in all-female growing environments. Documentation of sterility traits helps breeders identify genetic markers and breeding lines where pollen viability has been compromised or lost.
