Electrophoresis in starch gel was used to study the polymorphism of hordeins controlled by loci Hrd A, Hrd B, and Hrd F in 89 samples of the local barleys from South Arabia (Yemen). Overall, 36 alleles were detected for locus Hrd A; 48 alleles, for Hrd B; and 5 alleles, for Hrd F. The existence of the blocks of hordein components controlled by loci Hrd A and Hrd B was demonstrated. Calculation of genetic distances allows us to conclude that the barley populations from Yemen and Ethiopia are more similar compared with the populations from Egypt. This confirms the hypothesis of Bakhteev on the origin of Ethiopian barleys. |
