LOD≥5.0 used to declare significant digenic epistatic interactions (
P
≤
0.001). Additive effects, dominant effects,
digenic epistatic effects, and phenotypic contributions were obtained in the computational results of QTL
IciMapping 4.0. QTL nomenclature was done as described by McCouch (2008).
3.5 Statistical analysis
Phenotypic correlation analysis was performed with Pearson correlation type using SPSS (Ver.19). Phenotypic
distribution frequency analysis and graphic plotting of F
2
population was performed using Origin 9, and fitted
frequent distribution with GuassAmp function shown as follow.

Authors’ contributions
JL, RL, and BC conceived and designed the experiments. WZ and ZC performed the experiments. YW, QJ, JW, SL, LP, and BQ did
the field trials and involved in grain size related traits’ investigation, and further data processing. JL drafted the manuscript. RL and
BC revised the manuscript. All authors approved the final version of manuscript.
