  1. a“Recipient x donor” cross lines from which each NIL was produced in the previous MAB scheme [25]. bQTL introgressed in each NIL from the previous MAB scheme [25]. cLSMeans disease severity (DS) scores obtained on each genotype and scoring day from the CLMM analysis of each NIL set in experiments #1 and #2. Lsmeans scores were obtained from the DS score probabilities for each genotype and scoring day represented in Additional file 1A. LSMeans DS values ranged from −4.2 to 4.8, according to the scale of the latent variable implied by the CLMM. Significant differences between LSMeans values of the single-QTL NILs or the resistant control, and the control-NIL without QTL are indicated by *(0.01 < P < 0.05), **(0.001 < P < 0.01) and ***(P < 0.001). dAt two and three days after inoculation, LSMeans DS scores could not be estimated from CLMM since some lines did not have symptoms. eAt four days after inoculation, LSMeans DS scores were estimated from data obtained in one biological replicate in experiment #2
