  1. 1 In four repeats for the JEA x Col-0 RILs population and triplicates for the MAGIC lines. † Number of markers used to build the core genetic map (SSR or SNP) [32]. ‡ Detected by Interval Mapping -IM- or Krustal Wallis -KW-. * Significative after 1,000 permutations and at 95 % statistical confidence. LogP is equivalent to the -log10(p-value). bp: base pairs, Maximum LOD: score associated with the peak of the LOD plot using Map QTL, R2: Proportion of the phenotypic variation explained by the peak of the LOD plot using multiple QTL mapping (explained variance)
