Pomological Definition of Native Walnuts (Juglans Regia L.) Grown in Centrral Bitlis

Abstract

In this research conducted in native walnut population during 2003-2004 years in Bitlis, 17 walnut genotype having kernel weight over 5 g were selected and pomologically defined. Selected genotypes were determined to have a range of 32.90-41.22 mm for nut width, 29.96-38.32 mm for nut thickness, 32.14-36-86 mm for nut length, 10.94-17.20 g for nut weight, 5.48-8-50 g for kernel weight, 41.63-51.92% for kernel percentage and 1.22-1.98 mm for shell thickness. The kernel fullness of all genotypes except for one was good, kernel rottenness was not run into all genotypes. In addition, kernel colors of genotypes were light, dark, yellow and extreme dark. Findings pointed out that Central Bitlis district had valuable walnut genetic resources. © 2007 Asian Network for Scientific Information.
