  1. Variances are presented in percentage of total variance for the model without QTL effects (PED) and for the final selected QTL model (PED + QTL). QTL names are formed by heterotic group ID (A or B), the number of linkage group and the position in cM
  2. FFB Fresh fruit bunch yield
  3. BN Bunch number
  4. ABW Average bunch weight
  5. GCA General combining ability
  6. SCA Specific combining ability
