Abstract :The present study was conducted with the objective of conducting an agro-morphological characterisation of 22 eggplant genotypes collected from the Central Anatolia region, in addition to the subsequent evaluation of their genetic relationships. For the agro-morphological characterisation, observations and measurements were made for 29 traits (24 qualitative and 5 quantitative), which were determined by considering the criteria specified by UPOV and IPGRI. Principal component analysis and cluster analysis, obtained as a result of the analysis of the data belonging to the morphological traits, determined the level of genetic relationship between the eggplant genotypes in the gene pool. In the Principal component analysis, ten principal component axes explained 75.80% of the total variation, while in the cluster analysis, the distance range between the genotypes varied between 1.46 and 11.03 and the mean coefficient of the dendrogram (mean similarity) was 0.514 and the genotypes were divided into eight groups. As a result of the study, a significant morphological variation was found among the eggplant genotypes and it is believed that the data obtained will be an important source for similar researches such as sustainable plant breeding and conservation of genetic diversity.
