In this study, 24different chestnut genotypes were used. As the grafting method, the most commonly used tonguegrafting, split grafting, chip budding grafting, and side grafting method were used. All proceduresrelated to grafting were carried out in the greenhouses of the Düzce University Faculty of Forestry.In this study, local genotypes that are compatible with Marigoule chestnut were determined. As aresult, the native genotype, which showed the best adaptation to Marigoule seedlings, was 87.5%of Yalnızçam, and after that, 79.2% of the Ereğli Sefer genotype. The lowest fit showed Brokengenotype with 15% and Akçakoca1genotype with 17.5%. Besides, the compatibility of foreignvarieties Maraval, Marigoule, and Betizac were also investigated. As a result, Betizac had thehighest compatibility with 95%, while Maraval had 67.5%. The most successful in the graftingmethods applied was the side graft (74.2%) followed by tongue grafting (59.9%), splitting grafting(51.4%), and chip budding grafting (29.7%).en10.24925/turjaf.v9i8.1555-1559.4468info:eu-repo/semantics/openAccess[No Keywords]Article9815551559
