28989

This study was conducted out to determine of walnut genotypes with high fruit bearing and fruit quality within seedling population in Dicle, Hani, Egil and Kocaköy townships of Diyarbakir province and their villages during years 2004 and 2005. During this research, firstly 800 walnut trees were surveyed and 110 genotypes of them were marked and evaluated. Based on the results of these evaluations, 10 walnut genotypes were selected. Kernel ratio, fruit weight and kernel weight of the selected genotypes changed between 57.2-39.1%, 13.2-9.7 g and 7.13-5.62 g, respectively. The protein, the oil, the moisture, the ash the other matter contents of the genotypes changed between 20.0-13.7%, 66.2-57.8%, 4.9-1.8%, 2.98-1.76% and 20.2-9.0%, respectively. The protandrous, the protogynous and the homogymous of these genotypes were determined to be 5, 4 and 1, respectively. In addition, first leafing time, first bud breaking, fruit bearing in the lateral shoots and harvest time of them were found to be 2-6 April, 6-18 April, 75-90% and 15 September – 10 October, respectively.
