a Linkage group and the estimated confidence interval of QTL position in brackets (in Kosambi cM). b F values of significance of each QTL. c A and D effects representing additivity and dominance, respectively, related to UI3. Negative values in A indicate that alleles from UI3 have a positive effect on the resistance and negative values in D indicate UI3 dominance. Experiment-wide P value: * p ≤ 0.05, ** p ≤ 0.01, *** p ≤ 0.001. h2 = percent of the phenotypic variation explained by each QTL. PDC = pod disease score; PAUDPC = pod area under the disease progress curve; PAREA = size of the lesion on pods; PLDC = primary leaf disease score; PLAUDPC = primary leaf area under the disease progress curve; PLAREA = size of the lesion on primary leaves. Numerical superscripts refer to the race tested. d Gene action (D/A) A = additivity; PD = partial dominance; D = dominance; and OD = overdominance at a locus.
