a Markers were named based on the physical positions in reference genome CM334 (v.1.55). b LOD, log-likelihood. c R2 (%), percentage of variation explained by each maker. d A, value of the additive effect of each maker. e D, value of the dominance effect of each marker. A negative sign indicates that the increasing resistance of the QTL alleles was contributed by the resistant parent. f 2|d/a|, dominance ratio (DR), with a and d being the additive and dominance estimates, respectively. DR < 0.2 (additive), 0.2 < DR < 0.8 (partially dominant), 0.8 < DR < 1.2 (dominant), DR >1.2 (overdominant). g AUDPC, area under the disease progress curve. Lower mean AUDPC was associated with greater plant disease. B:B, allele of resistant line BVRC 1; A:A, allele of susceptible line BVRC25; A:B, heterozygous genotype.
