Table 3 Haplotype blocks significantly associated with the CIELAB color traits L*, a*, b*, and V (visual score) for kernel color in the UMN_C4 intermediate wheatgrass population. The column ‘LOD’ is a -log10*P-value of marker-trait association, ‘R²’ is the proportion of phenotypic variance explained by the significant SNP marker, ‘SigSNP’ shows if a SNP marker binned in the significant haplotype block was also significant in the single marker analysis
