Genome-wide association mapping for grain length. a Distribution of the grain length of 280 bread wheat accessions. b Manhattan plot of the four models (GLM, GLM_PC, MLM, MLM_PC) and associated quantile-quantile (Q-Q) plot representing the statistical association between each SNP and grain length. c The pairwise LD of SNPs surrounding the peak marker on chromosome 7A was calculated. The position of peak marker BS00021657_51 and WAPO-A1 is labeled
