Abstract:

 Objectives: This study was carried out to determine the phenological, pomological and morphological characteristics of the Çetiner hazelnut variety obtained through selection. Material and Method: In the study, trees of the Çetiner hazelnut variety, planted in 1991 at 2 x 3 m intervals in Hazelnut Research Institutes orchards, were used as plant material. The characteristics of this variety were examined and recorded between 2019 and 2021. These were budbreak, date of catkin and female flower, date of harvest, date of leaf fall, nut size, kernel size, nut weight, kernel weight, shell thickness, internal cavity, kernel percentage, empty nut rate, pellicle removal, wrinkled kernel rate, abortive kernel rate, double kernel rate, mold kernel rate, wormy kernel rate. Additionally, morphological characteristics were examined based on UPOV criteria. Results: According to the data obtained as a result of the study of leaf budbreak was 25 January- 10 February, date of male flower pollen releasing was 10-20 January, and date of female flower being receptive was 5-10 January.Nut size was 18.68 mm, nut weight was 1.83 g, kernel weight was 0.94 g, kernel rate was 53.4, abortive kernel rate was 1.6, double kernel, mold kernel and wormy kernel rate was 0, and pellicle removalrate was 95.8. The shell and kernel shape was determined to be spherical, the plant growth was strong, the tendency to give bottom shoots was high, and the leaf blade hairiness was weak. Conclusion: The Çetiner hazelnut variety, registered by the Hazelnut Research Institute in 2022, stands out with its features such as harvesting earlier than our standard hazelnut variety Tombul, having similar yields and not showing a tendency to periodicity.

 Amaç: Bu çalışma, seleksiyon yolu ile elde edilen Çetiner fındık çeşidinin fenolojik, pomolojik ve morfolojik özelliklerini belirlemek amacı ile yürütülmüştür. Materyal ve Yöntem: Denemenin materyalini Fındık Araştırma Enstitüsü arazisine 1991 yılında, 2 x 3 m aralıklarla dikilen Çetiner fındık bitkileri oluşturmaktadır. Deneme verilerinin alındığı 2019-2021 yılları arasında Çetiner fındık çeşidinde; yaprak açım zamanı, püs ve karanfil açım zamanı, hasat zamanı, yaprak döküm zamanı, meyve büyüklüğü, iç büyüklüğü, meyve ağırlığı, iç ağırlığı, kabuk kalınlığı, göbek boşluğu, iç oranı, boş meyve oranı, beyazlama oranı, buruşuk iç oranı, abortif iç oranı, çift iç oranı, çürük iç oranı, kurtlu iç oranına bakılmıştır. Ayrıca UPOV kriterleri baz alınarak morfolojik özellikleri incelenmiştir. Araştırma Bulguları: Çalışma sonucunda elde edilen verilere göre yaprak açım zamanı 25 Ocak- 10 Şubat, erkek çiçek püs açım zamanı 10-20 Ocak, dişi çiçek karanfil açım zamanı 5-10 Ocak olarak belirlenmiştir. Meyve büyüklüğü 18.68 mm, meyve ağırlığı 1.83 g, iç ağırlığı 0.94 g, iç oranı 53,4, abortif iç oranı 1.6, çift iç, çürük iç ve kurtlu iç oranı 0, beyazlama oranı 95,8 olarak tespit edilmiştir. Kabuklu ve iç meyve şekli küresel, bitki gelişimi kuvvetli, dip sürgünü verme eğilimi yüksek olarak belirlenmiştir. Sonuç: 2022 yılında Fındık Araştırma Enstitüsü tarafından tescil ettirilen Çetiner fındık çeşidi Tombul çeşidinden daha erken olgunlaşması, iç oranının benzer olması ve periyodisiteye eğilim göstermemesi gibi özellikleri ile ön plana çıkmıştır.
