Cyclamen, a popular decorative plant, is commonly found in gardens and pots. As wild Cyclamens are endangered, a study was conducted to explore the genetic potential for 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 region being 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. Additionally, describing the results based on the median, the fewest chromosome diversity was recorded for Kordkuy accession. On the whole, with the participation of all morphological, biochemical, and chromosomal level data, and with the help of principle components and cluster analyses, Cyclamen accessions were divided into two main clusters and a single accession. The Kordkuy accession was put alone and separated from other accessions. HCA analysis confirmed the separation of Kordkuy accession from other accessions, as expected from its superiority in most morphological traits. The findings of the present research can be used to improve Cyclamen breeding programs as well as evolutionary studies.
