Abstract Kulon Progo is one of the regencies in Daerah Istimewa Yogyakarta which has diverse of plant genetic resources, one is durian (Durio zibethinus). Exploration and characterization of durian genetic resources have been carried out. Durian diversity can be determined by characterization and it is also an effort to complete information in registering process of local varieties. Registration and releasing varieties are an effort that must be made to provide legal protection for the status of variety ownership. Characterization was done using descriptor for durian. The aim of this research was to determine some of Kulon Progo local durian diversity based on their morphology characteristic and then analysed it to determine similarity among cultivars by cluster analysis. Method research was exploration. The results showed that there were six local durian from Kulon Progo : Menoreh Kuning, Menoreh Jambon, Promasan, Banjar, Kendil and Cempli. Based on morphological characteristic, there were three groups of Kulon Progo local durian, namely group I consisting of Banjar, Kendil, Cempli and Menoreh Jambon, group II (Promasan) and group III (Menoreh Kuning).
