Stalk fracture angle and bulk segregant analysis (BSA) for the F2:3 population. a Histogram of the distribution of stalk fracture angles across the F2:3 population. The red arrows indicate the parental values. b Boxplot of the stalk fracture angles showing the difference between L-pool and H-pool lines used for BSA. c BSA results of stalk fracture angle. The X-axis represents the chromosome and the Y-axis represents the Δ (SNP-index). The blue and green dots indicate the SNPs; the red line is the regression line of the Δ (SNP-index) in each 1000 Kb window; the dark gray dashed line is the 95% threshold value; the region indicated by the yellow arrow is the putative QTL
