Plant height of non-mutagenized Kronos, the tall mutant T4-3822, and the M₄ mapping population. a Representative plants (six weeks after heading) of non-mutagenized Kronos and a T4-3822 M₄ sister line carrying the homozygous C allele at the peak SNP (C3986T on IWGSC_CSS_4BS_scaffold_4881784). b Plant height distribution in the M₄ population (n = 75). The 24 shortest and 24 tallest lines are highlighted in blue and red, respectively, while the remainder (n = 27) of the M₄ individuals are indicated in gray. A gray triangle denotes the plant height class of non-mutagenized Kronos. c Plant height of the 24 shortest (blue) and 24 tallest (red) lines from the M₄ population selected for exome sequencing. d Average plant height ± SE of the M₄ lines carrying homozygous T allele (n = 23), heterozygous C/T (n = 8), and homozygous C allele (n = 17) at the peak SNP (C3986T on IWGSC_CSS_4BS_scaffold_4881784, Table 1).
