Seventeen SRAP primer combinations produced 83 polymorphic markers, with a mean polymorphism of . The dendrogram created based on Nei’s unweighted-pair group method using arithmetic average (UPGMA) indicated that there were 4 main clusters, which was supported by principle component analysis (PCA). Cluster I primarily included only scald-resistant germplasm lines, while clusters III and IV consisted of only scaldsensitive lines, but cluster II had both scald-resistant and scald-sensitive barley germplasm lines. The coefficients of genetic similarity among the genotypes ranged from to , with a cophenetic correlation (r = ) suggesting that the cluster analysis moderately represented the similarity matrix. The results indicate that a large amount of the genetic diversity present could be of great use in the development of future scald-resistant barley lines.
