Table 1 Progenies and experimental designs used for QTL detection in four grapevine mapping populations

From: New stable QTLs for berry weight do not colocalize with QTLs for seed traits in cultivated grapevine (Vitis vinifera L.)

  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.
