From: Barley landraces are characterized by geographically heterogeneous genomic origins
Distribution and populations structure of the barley landraces in the Old World used in this study. a Colors correspond to the proportion of assignment to each of the four populations identified among landraces. b Secondary population subdivision for the optimal K = 4: Central European, Mediterranean, East African, and Asian. Each color represents the majority of assignment for four landrace populations. The Y-axis is percent composition with samples sorted along the X-axis geographically by longitude from west to east
