Abstract
Genetic diversity was investigated in a set of 27 barley genotypes, originated from Egypt, using 23 expressed sequence tag (EST)-derived simple sequence repeats (eSSRs), representatives of the seven barley chromosomes. Ninety-five alleles were detected among all the barley accessions. For 22 polymorphic eSSRs, the number of alleles per locus varied from 2 to 12, with a mean of 4.318 alleles per locus. The lowest and the largest number of alleles per locus among the seven homeologous groups was observed in homeologous group 5H and 4H with 3.00 and 6.33, respectively. The gene diversity increased as the number of alleles increased. Gene diversity for 22 ESTs loci varied from 0.137 for GBM1404 to 0.896 for GBM1015 with an average of 0.563. A significant correlation coefficient between gene diversity and the number of alleles was high, r = 0.741 (P < 0.01). Cluster analysis was conducted based on eSSRs data to group the barley genotypes and to construct a dendrogram. Four groups can be distinguished by truncating the dendrogram at gs value of 0.77.
