Abstract: | The aim of this study is to characterize 10 European chestnut (Castanea sativa Mill.) accessions which were selected among 80 accessions at the end of a selection study in Nazilli in Turkey. During the
harvest periods in 2001, 2002 and 2003, European chestnut accessions were examined. Nineteen morphological, pomological and
biochemical characters were used. Significant genotype×year interaction were found for all traits but one. Multivariate methods,
including cluster and principal component analysis were performed to characterize the accessions. The first five principal
components account for 86.44% of the total variance of all traits, indicating a high degree of correlation among the characteristics
analyzed. High level of phenotypic proximity was found between the accessions N-20-2 and N-5-1 based on pomological, morphological
and biochemical characteristics. |
