Hazelnut TONDA FRANCESCANA

Italian breeding excellence for your hazelnut orchard

"Tonda Francescana" is the result of long-term selection work by the Universita degli Studi di Perugia. Developed under the guidance of Agostino Tombesi, Daniela Farinelli, and Mirco Boco, this variety is highly regarded by commercial growers for its technological consistency. If your business model relies on mechanized harvesting, this variety offers the reliability needed for high-volume operations.

Production performance

In field conditions, Tonda Francescana stands out for its uniform, round shape, which is crucial for efficient automated sizing and processing lines. With an average fruit weight of 2.5–3.0 grams, the nut fills the shell perfectly, reducing the percentage of empty or underdeveloped yields. The variety is highly productive, provided the agronomic background is balanced—it is sensitive to micronutrient deficiencies, so consistent foliar feeding is essential for maintaining optimal nut size.

Operations and maintenance

From an owner's perspective, Tonda Francescana requires diligent pruning. The plant has a tendency to become dense, so canopy management starting from the first years of planting is vital. Regular thinning allows sufficient sunlight to reach the inner part of the bush, which directly affects nut quality and yield consistency. Regarding pest management, the variety shows moderate resistance; standard fungicide schedules are effective, provided you follow a strict timing program to protect the shell quality.

Technological highlights

• Mechanical Harvesting: The round shape is ideal for mechanical harvesters, ensuring minimal losses during the picking process.
• Processing: High kernel recovery rates during shelling significantly reduce operational costs at the processing facility.
• Hardiness: Well-adapted to moderate climates with good temperature tolerance, though it requires well-drained soils to avoid root-related issues.

Choosing Tonda Francescana from Universita degli Studi di Perugia is a strategic investment in standardization. The ease of calibration and predictable fruit weight allow for better planning of product sales, making it a strong candidate for premium processing markets.
