^aPea linkage group as assigned in [25]
^bLogarithm of odds
^cEffect of substituting Baccara alleles for PI 180693 alleles at the QTL. A positive sign indicates that QTL alleles increasing the resistance are contributed by the resistant parent PI 180693, whereas a negative sign means resistant alleles are contributed by the susceptible parent Baccara
