Extended Data Fig. 6: Phenotype variation profile among different heterotic groups.
For each box, the upper and lower boundaries represent the 25th and 75th percentile, respectively. The middle horizontal lines represent the median. The whiskers represent 1.5× the interquartile range. The dots beyond the whiskers represent outliers. The “compact letter display (CLD)” method is used to determine the multiple comparison results (conducted by the least significant difference method). Different letters above the boxes indicate significant differences (P < 0.05, Bonferroni correction) in a pairwise comparison. Sample numbers are shown in brackets on x axis. DTA: days to anthesis; KRN: kernel row number; EL: ear length; TBN: tassel branch number; EH: ear height; EP: relative ear height (ear height/plant height).
