Male sterility in Buddleja

Buddleja L.

The trait of male sterility in Buddleja is used in breeding to reduce the invasiveness of plants by limiting seed production. This is achieved through morphological defects of the androecium rather than classical mechanisms of cytoplasmic male sterility.

In the reference 8 varieties crop Buddleia, where this is mentioned in the description.

In Buddleja breeding, male sterility serves as a tool for controlling invasiveness, allowing to prevent uncontrolled self-seeding of the species Buddleja davidii. The trait is incorporated into cultivars of breeding series to reduce plant fertility.

The sterility mechanism manifests through morphological deviations in the development of the androecium, including underdevelopment or deformation of the anthers. The effectiveness of the trait is assessed by the reduction in seed viability, where the target threshold is considered a 98% reduction in seed productivity compared to fertile forms.
