Negative trade-off across 2 years between grain yield (GY) and grain protein content (GPC) in 504 RILs with awns (orange) and without awns (grey). a Scatter plots of GY (x-axis) vs GPC (y-axis), includes 16 founders and 3 recent varieties (triangles, only one measured in year 1) colored by release year. b The distribution of protein-yield deviation (PYD): the perpendicular distance from the symmetrical Thiel-Sen regression between GY and GPC, after Z-score normalization
