- Abstract
Population structure and relationships within and among 185 accessions of wild ( Hordeum vulgare ssp. spontaneum) and cultivated barley ( H. v. ssp. vulgare) from five countries in the West Asia and North Africa (WANA) region were studied using 36 simple sequence repeat (SSR) markers. The accessions were divided into subspecies/origin (S/O)-groups and marker results were analysed in relation to genetic diversity and genetic structure. Wild barley from WANA was found to be highly diverse. The landraces from different countries of the Near East showed genetic diversity that was nearly as high as the wild barley from the same country. Further analyses showed that wild barley from Palestine/Israel represented the group with the highest diversity and the most complex structure. However, this group was distantly related to the cultivated barley in WANA, while the wild barley from the rest of the WANA region was closely related to the cultivated WANA barley. The high diversity and the close relationship to the wild barley make the WANA landraces an interesting genetic resource for both conservation and exploitation.
