Determination of Superior Chestnut Genotypes in the Central Black Sea Region of Turkey

Abstract

This study was carried out with the aim of determining the superior genotypes of chestnuts as the 2'nd step of the selection study in the Central Black Sea Region of Turkey. 10 chestnut genotypes selected in the 1'st step of the study from Sinop and Samsun provinces were used in the study. Two locations were chosen; the first one was Fatsa County in the province of Ordu and the second one was Terme County in the province of Samsun. The yield and some fruit traits of the genotypes were examined between 2000 and 2005. The data was evaluated by the weighted-rankit method with the scores of the chestnut genotypes being determined by their qualitative and quantitative characteristics. Additionally, their relative values were evaluated with regards to general quality, nut size, earliness and suitability for making chestnut paste. The genotypes found to be superior were as follows: SE 3-12, SE 21-2, SE 21-9, 552-8 and 556-8.
