Determination of Morphological Differences Between Düzce Province Walnut Genotypes

Abstract

In this study, carried out to select walnut types from the population of seedling walnut trees in Duzce province, fruit samples were collected form 86 trees, then significant fruit properties were evaluated. According to results, 5 walnut types were selected as promising. In the selected types, fruit weights were measured as 12.08 g (81.DZC.36)-15.47 g (81.DZC.11), kernel weight as 6.09 g (81.DZC.70)-8.44 g (81.DZC.42), kernel ratio as %41.41 (81.DZC.11)-%59.01 (81.DZC.42) and shell thickness as 1.03 mm (81.DZC.42) - 2.28 mm (81.DZC.11). Shell color was determined as dark in all types, while inner color was amber in one type, other types were light amber. The selected types were in a good condition for full and sound interior ratio. Six types gave 100% full and sound inner.
