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
FFB Fresh fruit bunch yield
BN Bunch number
ABW Average bunch weight
GCA General combining ability
SCA Specific combining ability
