This study was carried out on Palaz and Sivri hazelnut cultivars grown in central Ordu and the surrounding area. The interrelationships among husk length, nut length, nut width, nut height nut weight, shell thickness, kernel length, kernel width, kernel height, kernel weight and percent kernel were determined using path analysis. | Tr.

Zeki BOSTAN, Ali İSLAM Karadeniz Teknik University, Faculty of Agriculture, Department of Horticulture, Ordu-TURKEY Received: Abstract: This study was carried out on Palaz and Sivri hazelnut cultivars grown in central Ordu and the surrounding area. The interrelationships among husk length, nut length, nut width, nut height nut weight, shell thickness, kernel length, kernel width, kernel height, , kernel weight and percent kernel were determined using path analysis. From the path analysis, it was found that percent kernel in Palaz cultivar was affected by shell thickness (r=**) and husk length (r=**) according to nut weight; in Sivri cultivar, it was affected by nut length according to nut weight (r=**) and by kernel width according to kernel weight (r=**). There were also negative effects on percent kernel from the other characteristics according to nut weight. The correlations of percent kernel-nut length, percent kernel-kernel width, percent kernel-kernel height and percent kernel-kernel weight in Palaz cultivar, and percent kernel-nut weight, percent kernel-kernel length and percent kernel-kernel height in Sivri cultivar were not significant. Palaz ve Sivri Fındık Çeşitlerinde Önemli Meyve Kalite Özellikleri Arasındaki Karşılıklı İlişkilerin Path Analizi ile Belirlenmesi Özet: Bu çalışma, Ordu Merkez ilçe ve köylerinde yetiştirilen Palaz ve Sivri fındık çeşitlerinde yürütülmüştür. Çeşitlerde, zuruf uzunluğu, meyve uzunluğu, meyve genişliği, meyve yüksekliği, meyve ağırlığı, kabuk kalınlığı, iç uzunluğu, iç genişliği, iç yüksekliği, iç ağırlığı ve iç oranı özellikleri arasındaki karşılıklı ilişkiler path analizi ile belirlenmiştir. Çalışma sonucunda, Palaz çeşidinde; iç oranına, kabuk kalınlığının meyve ağırlığından dolayı olan
