a,c,d,eChromosome, SNP ID, SNP name, and chromosome position are all based on the wheat 90K consensus map [41]; benvironment from which marker was identified as significantly associated with Δ; fnominal values; galleles for specific SNP markers; the underlined base represents the minor allele; the bold base represents the favorable allele if low Δ is desired; hminor allele frequency (MAF). Frequency of minor allele in the panel; ialpha ( ) denotes the SNP effect on the phenotype; jpercent phenotypic variation explained by the SNP.
