Eight QTLs were associated with the genome of the superior parent Seg5 and three QTLs linked to the genome of the inferior parent BY710. The chromosomal position of each QTL, the number of SNPs with significant linkage and the average Probability of linkage of all significant SNPs in the QTL are indicated. All QTLs indicated had a significant Probability of linkage >0.95 when linked to the Seg5 parent or <−0.95 when linked to the BY parent. QTLs 1, 6, 11, 14, 15 and 16 were found only in pool 2 (see Table 3) whereas QTLs 12 and 17 were common for both pools and designated 12.1 and 12.2 or 17.1 and 17.2 depending on the pool.
