After the genetic groups, the parental plants are listed in the treeid column, followed by the progeny generation plants. Notice that every parent generation individual has a genetic group indicated, whereas the progenies derived from those parents by open-pollination have the known mother plant identified but the genetic group label for the father. If progeny came from full-sib families, however, only the parents would be assigned to genetic groups (provenances).
The individual tree model is:
