Hazelnut variety Tonda Francescana, also known as Tonda Romana, is one of the most widespread and valuable varieties in the Lazio region, Italy. This medium-height and moderately vigorous tree is characterized by high yield — up to 3500 kg per hectare. The nuts of this variety have a round shape, an average kernel size of about 1.4 grams, and a nut weight of 2.7 grams, with a kernel extraction rate reaching 44-48%. The shell is slightly longer than the nut itself, but most nuts practically lack shells, facilitating processing. Kernels are usually round and fiber-free, which makes blanching difficult, but they possess a strong hazelnut aroma, making this variety one of the best for the confectionery industry. Tonda Francescana is resistant to the bud mite, enhancing its reliability and reducing the risk of yield loss. Male and female flowers bloom in mid-season, requiring suitable pollinators such as Lansing, Tonda di Giffoni, Nocchione, Mortarella, and Merveille de Bollwiller to ensure good fruit set. The variety is characterized by moderate to high yield, making it attractive for commercial cultivation. Additionally, plants are well-adapted to European climate conditions, as confirmed by C.A.C and CIVI ITALIA ISMEA FERRERO certification. This hazelnut variety is prized for its flavor and high kernel content, making it popular in food and confectionery industries. Thanks to its strong nutty aroma and fruit quality, Tonda Francescana is widely used in the production of various nut-based products. Resistance to pests and adaptation to climatic conditions ensure a stable and high-quality yield, making this variety one of the best choices for growing hazelnuts in Europe.
