Phylogenetic Relationships of some Wild and Cultivated Barley Accessions Using Seed Storage Protein Markers

Abstract

Barley is of renewed interest throughout the world because of its nutritional value and low glycemic index. It has been suggested that biochemical accomplished with molecular markers can be used to solve population diversity of barley. Hordeins are the storage proteins of the wild and cultivated barley samples. For this reason, we analyzed genetic diversity in the storage protein hordein encoded loci in seeds from 106 accessions of wild and cultivated of barley accessions from different countries. Cluster analysis by using Nei genetic distance and UPGMA methods all studied wild and cultivated barley accession divided into 6 main groups. Groping of Azerbaijan wild and cultivated barley accession in the same cluster showed that Azerbaijan cultivated barley accessions was clearly distinguished from its wild accessions. The presence of high level of diversity among the tested genotypes grouped into divergent clusters indicated their suitability for further research can be done in this direction by selecting superior barley genotypes.
