  1. 1Reciprocal cross.
  2. 2Seed dry weight not evaluated in SxG.
  3. 3Partial QTL detection in ten genomic regions only.
  4. 4Phenotypic data already available from [46] and [25], with only slight differences in phenotyping protocol.
  5. 5Seed traits not evaluated in 2002.
  6. 6Phenotyping of one replicate only in 2005.
  7. 7Phenotyping on a sample of 142 individuals in 2005.
  8. 8Maps of Huang et al. [49] but based on the Kosambi (instead of Haldane) mapping function.
