The highest prediction accuracy among different marker types is highlighted in bold font. Single-trait QTL, quantitative trait loci (QTL) identified using all models for a specific trait, i.e., a different marker set for each trait; All-trait QTL, all unique QTL identified using all models from all seven traits, i.e., the same marker set for all seven trait; Overall, phenotype BLUEs over four years and two locations, Morden, Manitoba and Saskatoon, Saskatchewan; YLD, seed yield; DTM, days to maturity; PRO, protein content; OIL, oil content; IOD, iodine value; LIO, linoleic acid content; LIN, linolenic acid content; SNP, single nucleotide polymorphism. The letters after r ± s values represent statistical significance of r values among 63 combinations of seven traits, three marker sets, and three location levels (two locations plus overall BLUEs over two locations).
