  1. a Meta-QTL names are coded as follows : MQTL-Ae = Meta-QTL detected for resistance to A. euteiches; MQTL-Morpho = Meta-QTL detected for morphological and phenological traits (flowering time and plant height). On each Linkage Group (LG), MQTL-Ae and MQTL-Morpho, which co-localize, are mentioned by asterisks. Meta-QTL indicated in bold correspond to the seven main consistent genomic regions identified for resistance to A. euteiches.
  2. b QTL position at the LOD (Log of likelihood ratio) score peak, from the first marker of the linkage group in cM Kosambi.
  3. c 95% confidence interval of the meta-QTL given by MetaQTL software, in cM Kosambi.
  4. d Mean and standard deviation of confidence intervals (estimates according to [55]) of all independent QTL belonging to each meta-QTL, in cM Kosambi.
  5. e Number of initial QTL (redundant and independent) underlying each meta-QTL.
  6. f Range of percentage of phenotypic variance (R2) explained by individual initial QTL underlying each meta-QTL.
  7. g Range of LOD-1 confidence intervals of all initial QTL underlying each meta-QTL.
  8. h Number of variables for which each RIL parental allele contributed to increased resistance to A. euteiches, increased earliness or short plants, at each meta-QTL. No values indicate missing data.
