Abstract
Genetic diversity among 35 accessions of Ae. cylindrica using 17 ISSR primers were investigated. Totally, 190 alleles were amplified and 188 alleles (98.95%) o were polymorphic. Number of Amplified alleles ranged from 6 to 20 with average 11.18 alleles for each primer. Polymorphic information content (PIC) varied from 0.10 (primer UBC841) to 0.35 (primer UBC836). Marker index criterion ranged from 0.6 (primer UBC841) to 6 (primer 15). Cluster and Principal Coordinate Analysis could not completely separate accessions and showed no association between molecular diversity and geographic diversity of genotypes, indicating that there is high genetic diversity among accessions. West and south-west genotypes showed more diversity than genotypes from north and north-west of the country. Therefore, the center of diversity and origin of Aegilops cylindrica might be the western and south-western regions of country and this species might transferred from these regions to the northern parts of the country. Results of this study showed that ISSR markers are useful tools for management of genetic resources of wheat and their wild relative species.

Abstract
The common fig (Ficus carica L.), one of the most important fruit species, belongs to Moraceae family and is widely distributed in Iran. In this study, genetic variations among some genotypes of common fig collected from six different regions of Ilam province (Iran) were evaluated based on RAPD and ISSR markers. A total of 73 and 29 alleles were produced by 14 RAPD (with their sizes ranging from 350 to 2500 bp) and 5 ISSR (with their sizes ranging from 150 to 1500 bp) primers, respectively. The number of observed alleles for RAPD primers ranged from 1 (OPA-03) to 9 (OPA-09 and UBC-429), with an average of 5.21 alleles per locus. Also, the number of observed alleles for ISSR primers ranged from 3 (UBC-807) to 8 (UBC-810 and UBC-414), with an average of 5.8 alleles per locus. The highest and lowest values of Shannon's information index (I) was observed in the UBC-429 (2.18) and OPA-03 (0.12) primers, respectively. The Jaccard's genetic similarity coefficient ranged from 0.12 to 0.73 among genotypes based on RAPD data, while for ISSR it was recorded from 0.07 to 1. Also, based on RAPD and ISSR data at a similarity coefficient of 0.45, the unweighted pair group method with arithmetic mean (UPGMA) cluster analysis divided the genotypes into six major groups. As a conclusion, there is a high genetic variability among fig genotypes, which is an important consideration for classification, utilization of germplasm resources and breeding programs of fig.
