Fig. 1From: Genome-wide association studies and whole-genome prediction reveal the genetic architecture of KRN in maizePhenotypic analysis. a Correlation analysis of the KRN phenotype among XX, BJ and GZL. The frequency distribution diagrams of KRN in three environments were plotted, and the correlation coefficient between each pair of environments was calculated. b Violin plots of KRN in the subgroups (P, Lancaster, TSPT, LRC, and Reid) of this association mapping panelBack to article page
