y)Q3, Q6, and Q7 indicate QDhd.jbnu-3B, QDhd.jbnu-6B, and QDhd.jbnu-7D, respectively. Mean values of the doubled haploid lines carrying the Keumkang allele and the Olgeuru allele are indicated for each QTL. Asterisks indicate significance (*P < 0.05, **P < 0.01 and ***P < 0.001; ns: not significant) from the three-way factorial ANOVA with the year (2017, 2018, and 2019) as a random factor and the three QTLs as fixed factors. Phenotype variance explained (PVE) is indicated only for significant effects. QDhd.jbnu-3B, QDhd.jbnu-6B, and QDhd.jbnu-7D were represented by the markers AX-95081398, AX-94511377, and AX-94523269, respectively.
