Differences in grain weight per ear between the three genotype clusters. The dashed black line indicated the mean of a phenotypic component from all samples without clustering. The black plus sign indicated the mean of a given phenotypic component from each cluster. An ANOVA was used to determine whether differences exist between three-cluster means. The Wilcoxon rank-sum test was used to compare each cluster against all genotypes without clustering. The following convention for symbols indicated statistical significance: p > 0.05 (ns); p ≤ 0.01 (**); p ≤ 0.001 (***). The total sample size remains 453, excluding missing values
