DArTseq Genotypic and Phenotypic Diversity of Barley Landraces Originating from Different Countries

Landraces are considered a key element of agrobiodiversity because of their high variability and adaptation to local environmental conditions, but at the same time, they represent a breeding potential hidden in gene banks that has not yet been fully appreciated and utilized. Here, we present a genom...
