  1. NILs carrying resistance alleles at zero, one, two or three of the seven A. euteiches resistance QTL in pea [25]
  2. aNILs are coded as follow: NIL“NIL set number”-“0 for zero QTL or QTL number(s)” “sister NIL letter (a or b)” [25]. bLines used as donors of resistance alleles at one to three QTL in the Marker-Assisted Backcrossing (MAB) scheme [25]. cSusceptible parents of the RIL populations in which the QTL were detected, used as reference recipient parents in the MAB scheme [19]. dQTL introgressed from the donor lines in the MAB scheme [25]
