  1. a Field locations/resistance evaluation criterion are coded as followed : RI = Riec/Belon (FR); DI = Dijon (FR), TPX = Templeux (FR), PLM = Pullman (USA); LS = LeSueur (USA); RRI = Root Rot Index; ADI = Aerial Decline Index; DW = Dwarfism; DWL =% Dried Weight Losses. Controlled-condition scoring traits are indicated by the name of the A. euteiches strain (RB84, Ae78, Ae85, Ae87 = SP7, Ae106 and Ae109).
  2. b Range of percentage of phenotypic variation explained by each resistance-enhancing allele at each meta-QTL, depending on the variable.
  3. c Confidence interval of the single or two meta-QTL region (1st value) and of the genomic region encompassing LOD-1 confidence intervals of all initial QTL underlying the meta-QTL (2nd value), in cM Kosambi.
  4. d Recommended co-dominant SSR markers covering the genomic region encompassing LOD-1 confidence intervals of all initial QTL underlying the meta-QTL. Mean allele sizes are indicated in parentheses for each SSR.
