Cyclamen, a popular decorative plant, is commonly found in gardens and pots. Since wild Cyclamen are endangered, a study was conducted to explore the genetic potential of wild Cyclamen, focusing on their morphology and chromosomal diversity among eight accessions. A total of 23 phenotypic-biochemical traits were evaluated along with chromosome counting. The morphological measures showed a humble range of variation, particularly in the number of flowers, peduncle diameter, number of leaves, hypocotyl length, and hypocotyl weight, with the Kordkuy accession being the largest and the Deylaman accession the most seeded. Cyclamen chromosome counting indicated 15 chromosomal levels, implying a significant chromosomal diversity among the accessions, with the Pasand accession exhibiting the highest level of chromosomal diversity (14 chromosomal levels). Furthermore, only the Pasand accession had the greatest chromosomal level (2n=48) among the accessions. By describing the results based on the median, the smallest chromosomal diversity was recorded in the Kordkuy accession. Cyclamen accessions were divided into two main clusters and a single accession. The Kordkuy accession was separated from the other accessions. HCA analysis confirmed the separation of the Kordkuy accession from the other accessions, as expected from its superiority in most morphological traits. The current findings can be used for improving Cyclamen breeding programs as well as evolutionary studies. We suggest more focus on the utilization of wild genetic resources to conserve Cyclamen varieties and strengthen their genetic background.
