Promising Native Walnut Genotypes (Juglans Regia L.) of the East Black Sea Region of Turkey

Abstract

In order to select promising native walnut genotypes, characteristics of trees situated on the Black Sea Region of Turkey during 1997 to 1999 were examined with regard to fruit properties. The walnut population consisted of 4200 seedling trees. Fifteen native genotypes selected were evaluated as promising. The genotypes exhibited a range of 11.8-18.7 g for inshell fruit weight, 6.25-9.23 g for kernel weight, 48-60% for kernel percentage, 1.02-1.75 mm for shell thickness, 65-100% for terminal fruitfulness and 30-75% for lateral fruitfulness.
