Figure 7.

Comparisons of genomic prediction accuracy (r ± s) using different marker sets, including all single nucleotide polymorphisms (SNPs) and quantitative trait locus (QTL) sets identified by different statistical models: (A) SNP based single-locus model (SS), (B) SS + SNP based multi-locus model (SM), (C) haplotype-block-based model (BM), and (D) all three models of SS+SM+BM (All). For each trait, three marker sets were compared for prediction accuracy: All SNPs, QTL of all traits (QTL together for all seven traits), and QTL of single traits (QTL for individual traits). Different letters represent statistical significance of r values among different types of markers within each trait. A tag quantitative trait nucleotide (QTN) for each QTL was used for analyses. YLD, seed yield; DTM, days to maturity; PRO, protein content; OIL, oil content; IOD, iodine value; LIO, linoleic acid content (LIO); LIN, linolenic acid content.
