dc.description.abstract Genetic variability in the 143 core accessions of wild barley, Hordeum vulgare ssp. spontaneum, was assessed by allozyme analysis. A total of 34 alleles were detected at ten isozyme loci. All loci were polymorphic except Pgd-1, which was monomorphic. Est-2 and Est-4 were the most diverse loci, with genetic diversity values of 0.747 and 0.686, respectively. The comparison of the results with those of previous studies indicates that all alleles occurring in cultivated and wild barley are observed in this set of the wild Barley Core Collection. Only one allele (Pgd-1 Tj ) was absent. It is noteworthy that one new allele at the Ndh-2 locus and another new allele at Aco-2 locus were first detected in the present study. Nine of the 34 alleles were rare and detected only in one to four accessions. The genetic similarities among the 143 accessions ranged from 0.18 to 1.00. Data analysis based on clustering and principal coordinate analysis showed that a high level of genetic variability exists in this set of core accessions, and indicated that some duplication probably exists in this set core based on the present study. en_CA
