Tonda Pacifica

Tonda Pacifica: A Breeding Breakthrough from Oregon State University

Tonda Pacifica represents the pinnacle of research conducted by Oregon State University, specifically designed to address the most pressing challenge in hazelnut cultivation: susceptibility to Eastern Filbert Blight (EFB). While many heritage cultivars are struggling against these persistent pathogens, this hybrid offers unparalleled genetic resistance, making it an essential asset for any modern, sustainable commercial orchard.

Agronomic Profile and Yield Performance

The primary advantage of this cultivar lies in its unique combination of disease resilience and superior nut quality. The nuts are uniformly round with a weight of 3–3.5 grams, making them highly desirable for both the confectionery industry and the premium retail snack market.

• Phytosanitary Defense: Beyond its core resistance to Eastern Filbert Blight, the variety shows significant tolerance to Monilinia and Fusarium, allowing for a more efficient and environmentally friendly spray program.
• Reliability: Developed by Shawn A. Mehlenbacher and his team, the plant is optimized to perform consistently, maintaining fruit size and quality even under varying environmental stresses.
• Processing Efficiency: The ideal round shape of the nut simplifies the calibration and cracking process, maximizing kernel recovery rates in automated systems.

Who is this variety for? Tonda Pacifica is ideal for growers focused on long-term orchard health and reduced chemical dependency. By selecting this cultivar, farmers are safeguarding their investment against the most destructive diseases that can decimate traditional orchards in just a few seasons. It is a choice for those who prioritize agricultural stability and scientific rigor, backed by the extensive expertise of Oregon State University.
