Batı Anadolu’da Yeni Belirlenen Bazı Kestane Genotiplerinin Farklı Aşılama Yöntemleriyle Çoğaltılması

Abstract

Aim of study: In the study, the most successful grafting method and chestnut genetypes that are best adapted to the Düzce Kaplandağı chestnut population were tried to be determined. Area of study: Chestnut seeds used as rootstock material were collected from natural chestnut forests of Kaplandağı, Cumayeri district of Düzce province. Material and methods: In this study, for the first time identified by us, 20 well-known fruit qualities, two locally known (Serdar and Erfelek), and three foreign (Maraval, Marigoule, and Bethizac) chestnut genotypes were used. It was investigated the success of grafting methods by using 25 different chestnut genotypes and three different grafting methods (budding, the cleft and tongue grafting). 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, Hacıömer, Serdar, Akçakoca 1, Alaplı 1, Çongara, Fındıklı 1, Gümeli 1, Fındıklı 2, Ereğli-Yazıören, Paşaormanı 2, Gümeli black, Fındıklı 3, Ereğli-Nevzat, Gümeli yellow, Akçakoca yellow, Yığılca-Vedat, Yığılca-Çakır, Ibradı 2. and Maraval, Marigoule, Bouche de Bethizac. Main results: It was determined that stabile temperature and humid conditions affected grafting achievement on chestnut 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 Çongara genotypes (98%) had the highest while the Fındıklı 2 genotypes (20%) had the lowest grafting success. As a result, the most successful grafting methods were cleft and tongue grafting, and the most successful grafting genotypes were found as Çongara, İbradı 2 and Alaplı 1. Also, the sapling obtained from the study were taken under ex-situ protection in Düzce University campus as a chestnut orchard. Highlights: Also, two of them (Pasaormanı and Akçakoca 1) are observed to resist against the gall wasp.
