Numbers, main effects and contributions of QTLs for yield-associated traits in wheat DH lines.

1YP (g): Yield per plant; NSP: Number of spikes per plant; NGS: Number of grains per spike; TGW (g): 1000-grain weight; TNSS: Total number of spikelets per spike; NSSS: Number of sterile spikelets per spike; PFSS: Proportion of fertile spikelets per spike; SL (cm): Spike length; DSS: Density of spikelets per spike; PH (cm): Plant height; 2a: additive main effects; aa: epistatic main effects; Effects: the mean of absolute additive main effects (a)/the mean of absolute epistatic main effects (aa); PVE: the mean of phenotypic variations explained by additive main effects (a)/the mean of phenotypic variations explained by epistatic main effects (aa).
