Percentage of variance components over the total phenotypic variance for all traits. CRR, crown rust resistance; SY, seed yield; TKW, 1000-kernel weight; NDF, neutral detergent fiber; FR, fructan. See text for variance component definitions. i, additive genetic variance within parent populations (PPs); p, additive genetic variance among PPs; il, genome × location variance; ily, genome × location × year variance; ply, genome × location × year variance among PPs; ilys, genome × location × year × score variance; plys, genome × location × year × score variance among PPs; pp, variance among PPs combinations; c, variance among sub-trials within YLTs; cs, variance among sub-trials within YLST; o, environmental variance within plots and across scores; e, residual variance.
