characteristics of domestication and modern breeding. Despite this, little is known about the
genetic and molecular mechanisms of grain size and weight in barley. Here, we evaluated
nine traits determining grain size and weight, including thousand grain weight (Tgw), grain
length (Gl), grain width (Gw), grain length-width ratio (Lwr), grain area (Ga), grain perimeter
(Gp), grain diameter (Gd), grain roundness (Gr), and factor form density (Ffd), in a double …
