Compatibility of some chestnut (Castanea sativa Mill.) genotypes to Düzce Kaplan mountain chestnut rootstocks

Anatolia is the motherland of chestnut as it is in many kinds of fruit, and one of the most ancient cultures. Anatolian chestnut, both fruit, as well as the valuable wood, is an important broadleaved species of Turkey. Anatolian chestnut spread in different geographical regions of Turkey shows, in Duzce province is one of the natural and optimum distribution area. There are a lot of research in the world literature on the detection, development and conservation of varieties, however, there are limited in our country. In this study, it was tried to determine the success of grafting by using 10 different chestnut genotypes and 3 different grafting methods in Kaplandağı (Düzce) chestnut. The seedlings of the Kaplandağı chestnut population were used as the rootstock chestnut genotype. The genotypes which were grafted on the rootstock were types of Kabalak, İbradı, Paşaormanı, Erfelek, Marigoule, Hacıömer, Serdar, Akçakoca, Alaplı, Çongara, Kabalak, Fındıklı 1, Gümeli 1, Fındıklı 2, Ereğli-Yazıören, Paşaormanı 2, Gümeli siyah, Fındıklı 3, Ereğli-Nevzat, Maraval, Gümeli Sarısı, Akçakoca Sarısı, Bethizac, Yığılca-Vedat, Yığılca-Çakır, Ibradı 2.The grafting method such as cleft, tongue, and budding were used. Variance analysis was used to determine the effect of grafting type and method on retention success. It was determined that stabile temperature and humid conditions affected grafting achievement on chesnut genotypes and grafting techniques. While the lowest grafting success was in the budding, the cleft and tongue grafting methods were the same and have a grafting success rate of 63%. Among the chestnut varieties, the highest grafting success was determined in the Çongara genotypes (98%) and the lowest grafting success in the Fındıklı 2 genotypes (20%). In terms of interactions; all of the grafting was retained in the grafting method of cleft and tongue. The lowest grafting success was found in seedlings of Serdar with budding grafting method. As a result, the most successful grafting methods for the rootstock Kaplandağı seedlings, which are important chestnut genotypes, were cleft and tongue grafting, and the most successful grafting varieties were found as Çongara, İbradı 2 and Alaplı 1.
