Hordein Polymorphism in Ethiopian Barley

Hordein Polymorphism in Ethiopian Barley Using starch gel electrophoresis, polymorphism of hordein-encoding loci Hrd A, Hrd B, and Hrd Fwas studied in 147 accessions of local Ethiopian barley cultivars. Loci Hrd A, Hrd B, and Hrd Fwere shown to have 26, 36, and 4 alleles, respectively. The allele frequencies in the collection examined varied from 0.17 to 45.72%. For loci Hrd Aand Hrd B, families of blocks of hordein components were found. Based on the allele frequencies and their combinations at loci Hrd Aand Hrd Bas well as the numbers of families of component blocks of hordeins A and B, we identified genotypes that could be considered as the most ancient in Ethiopia. A catalog of hordein variant encoded by these loci was created. The list of hordein genetic formulas for the studied accessions is presented. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

Using starch gel electrophoresis, polymorphism of hordein-encoding loci Hrd A, Hrd B, and Hrd Fwas studied in 147 accessions of local Ethiopian barley cultivars. Loci Hrd A, Hrd B, and Hrd Fwere shown to have 26, 36, and 4 alleles, respectively. The allele frequencies in the collection examined varied from 0.17 to 45.72%. For loci Hrd Aand Hrd B, families of blocks of hordein components were found. Based on the allele frequencies and their combinations at loci Hrd Aand Hrd Bas well as the numbers of families of component blocks of hordeins A and B, we identified genotypes that could be considered as the most ancient in Ethiopia. A catalog of hordein variant encoded by these loci was created. The list of hordein genetic formulas for the studied accessions is presented.
