Development of new varieties at VDF Specialty Seeds is informed by a strong commitment to research and development. Incorporation of modern plant breeding methods increases the precision of our breeding efforts and the quality of new plant varieties.

We maintain a consistent connection to the scientific process and community through the public university system and scientific conferences. Results of research supporting our work is evidenced through publication in various peer-reviewed journals.
