Abstract
Barley (Hordeum vulgare L.) has been cultivated over millennia, making it one
of the oldest domesticated crops (Salamini et al. 2002). Ranking fourth in global
cereal-crop production, it is used for animal feed, brewing malts, and human consumption
(von Bothmer et al. 2003). Given barley’s long history as a crop involving
migration and selection leading to adaptation to different environments and
agroecology gradients, leading to a plethora of uses, it has the potential of being
an excellent model for further elucidation of agricultural responses to changing
and evolving climates (Dawson et al. 2015). Barley landraces are genetically heterogeneous
populations comprising inbreeding lines and hybrid segregates generated
by a low level of random outcrossing in each generation (Nevo 1992).
