Average macroscopic infection scores for VxSSC recombinant inbred lines (RILs) grouped according to presence (+) or absence (−) of the resistance allele of QTLs mapped for Blumeria graminis f.sp. tritici (Bgt) and f.sp. hordei-murini (Bghm)

Corresponding resistance alleles of each QTL are into brackets (V = Vada; SC = SusBgtSC). Values in each column that share the same letter are not significantly different (P < 0.05)
aTotal number of RILs analysed: 104 for Bgt and 105 for Bghm. The number of RILs in each group differed slightly (± 2 RILs) between Bgt and Bghm scores because the peak marker of Rbgnq3 was different for the two ff.spp. or because of missing phenotyping data. Four RILs were excluded from the analysis because there was a recombination point close to the peak marker of Rbgnq1
