  1. Genotypes represent a random sample of 25 inbreds from the WiDiv diversity panel, listed in Additional file 1: Table 1. Seed sources represent inbred seed stocks produced in summer nurseries spanning 2010, 2012, and 2013. The analysis of variance was performed on the mean phenotypic values of 9 kernels per replication after omitting outliers with studentized residuals that exceeded ± 3. Residuals represent the interaction of all terms included in the model
  2. k, swelling coefficient; ΔA % increase in kernel area after 22 h; df, degrees of freedom
  3. ***p <0.001; **p <0.01
