Turkey is one of the most important countries in the world for plant genetic resources and genetic diversity. Genetic
resources are characterized by morphological and agronomical traits. There is a need to collect, characterize and evaluate
remnants of local populations before they disappear. Morphological characterization is the first stage of the identification
and classification of genetic resources. In this study, the aim was to determine the similarities and differences in the
morphological variations of the eggplant populations collected from different eco-geographical regions of Turkey. Seventy
five populations of eggplant were characterized using standard morphological descriptors specified by the IBPGR. The
phenotypic diversity in their fruit characters was also assessed. Cluster and Principal Component Analysis (PCA) was
performed to determine the relationships among these accessions and to obtain information on the fruit characteristics
for the definition of groups. The principal component analysis showed that the first four principal component axes
explained 71.38% of the total multivariate variation. The results demonstrated many differences in fruit traits in the
detailed eggplant populations. Clustered into nine groups, a dendrogram was prepared to evaluate the morphological
differences among the populations. It revealed a high degree of variation. The results provided information on the
diversity, and this identified eggplant genetic resources to be evaluated for the development of new candidate varieties
in future breeding activities.
