| Abstract | ||||
| Chromosome count and karyotype study were performed on the available nine populations of the endangered endemic species Silene schimperiana Boiss., section Sclerocalycinae (Family: Caryophyllaceae), recorded only in a few localities in Sinai Peninsula, Egypt. The species studied showed chromosome number 2n=2x=24 for the first time in Egypt. The populations studied of S. schimperiana showed significant values of Pearson’s correlation according to karyotypic characters. The cluster analysis based on karyotypic characters divided the studied populations into two groups with 92% similarity coefficient. | ||||
