Abstract :

The genus Cotoneaster L. belongs to the genus Rosaceae. In the study, 17 plant samples were examined based on morphological studies and the nucleus sequence of ITS nrDNA. The results showed that there was a significant difference between all quantitative morphological traits. The studied species were classified into five groups. The pattern of species analysis based on morphological traits and molecular sequencing are very similar. There are similarities and differences between the studied species in terms of the studied traits. Molecular cladogram showed that the genus of Cotoneaster with consistency index (CI) is 0.68. Among some species of this genus such as C. pseudodiscolor and C. discolor, morphological similarity of traits such as leaf shape, density of lower surface hairs, and hairs on the fruit is observed, If it is genomically different and because it is not morphologically consistent with the description of the identified species of milk thistle in Iran and neighboring countries. Therefore, we consider it as a new species for Iran and define it as C. pseudodiscolor. In addition, the species C. morrisonesis and C. franchetti are a new record of this genus and have a separate cluster in their phenogram. , the present study is the first study in the field of genetic diversity in Iran (Hyrcanian province) using nuclear markers (ITS) in accurate species identification Is the first step in breeding this valuable taxon, which will be addressed in the present study.
