Genotypic differences in maize AGB (kg/m2). a On June 28, 2017. b On July 11, 2017. DH, Mixed, TEM and TST represent four genetic backgrounds of maize. The dashed black line indicates the mean biomass from all plots (i.e., baseMean). The black plus sign indicates the mean biomass from each genetic background (i.e., group). ANOVA is used to determine the existence of differences among four-group means. The Wilcoxon signed-rank test is used to perform comparison of each group against all without grouping (i.e., baseMean). The following convention for symbols indicates statistical significance: p > 0.05 (ns); p ≤ 0.05 (*); p ≤ 0.01 (**); p ≤ 0.001 (***); p ≤ 0.0001 (****). When the test is significant, it is found that DH group is significantly low-AGB compared to all and TST group is high-AGB compared to all. Because the test is not significant, there is no significant difference in the AGB between Mixed group and all
