Aydin Chestnut Product Description and Distinctive Features: Chestnuts, belonging to the Fagaceae (Beech family) along with oaks (Quercus sp.) and beeches (Fagus sp.) within the Fagales order, are a type of hard-shelled fruit. Chestnuts have been known as valuable trees for a long time. Their shells, wood, leaves, and charcoal are utilized for various industrial purposes. However, economically, the most important product is the fruit. The fruits can be evaluated for consumption as a table nut or processed into various forms as an industrial raw material. One of the primary methods of assessment, aside from fresh consumption, is the production of chestnut sugar confectionery. When examining the chestnut genotypes of the Nazilli district in Aydın Province, which are found to have superior characteristics in terms of "fruit size," a crucial criterion in chestnut selection studies, it is observed that they have quite large fruits. The selected six genotypes have fruit weights ranging from 13.445 g to 19.383 g, and the number of fruits per kilogram is determined to be between 51 and 78. These values obtained for fruit size are significantly higher than the fruit size values of types involved in previous selection studies in other regions. For example, in a chestnut selection study in the Marmara Region, the fruit weights of the types ranged from 5.00 to 21.400 g. Similarly, in a selection study conducted in the Erfelek district (Sinop), when the fruit weights of the types were examined over three years, the lowest was 5.46 g, and the highest was 10.78 g. These values are approximately twice as much as those of Nazilli chestnuts. In a selection study in the Aegean Region, the fruit weights of the selected types ranged from 8.85 g to 18.51 g. In this regard, it is revealed that the chestnuts from Nazilli are larger in terms of fruit size compared to chestnuts from the Aegean Region. In the region where the research was conducted, the examined and selected chestnut types generally have a "fruit shell" that is shiny and typically chestnut-colored. However, it varies from matte light brown to dark brown, depending on the types.When the chestnut genotypes selected from the Nazilli region are evaluated in terms of "seed coat peelability" and "seed penetration status" (which are crucial for processing chestnuts into sugar), it is generally observed that the seed coat penetrates the seed very slightly, and the seed shell is easily peelable. Production Method: "Aydın Chestnut" is an agricultural product. In other words, it is a "raw material." This raw material can be evaluated either for consumption as a table nut or processed into a "product" in the industry. Scientifically, chestnuts are propagated using "vegetative methods," one of the propagation methods. The most commonly used vegetative propagation method is "grafting." In addition, chestnuts can also be propagated through methods such as layering, rooting cuttings, and tissue culture. Various grafting methods can be used for chestnuts, including bud grafting, T-budding, patch budding, chip budding, and tube budding. Additionally, to shorten the seedling cultivation period, "Seed and Young Plant Grafts" can be applied. For chestnut orchard establishment, grafted seedlings can be used, or seeds can be sown in place, and after achieving sufficient growth, on-site grafting can also be performed. Various grafting methods mentioned above can be used for chestnuts. The scions used in grafting should be obtained from disease-free trees with high-quality and abundant fruits.To economically obtain products with chestnut seedlings produced in the mentioned ways, and to establish a chestnut plantation, a suitable orchard location is selected based on ecological factors. Then, the planting, row spacing, and inter-row spacing of chestnut seedlings are done with a spacing of 10-12 m. The planting time is in spring after the risk of frost has passed but before bud break.
