The genetics of fertility restoration was studied in A × B, A × R, B × B and B × R crosses. Based on near complete agreement of segregation patterns in various crosses, a four gene model has been suggested. It may be necessary to account for a fifth gene for fertility restoration on VZM2 and GI steriles. The genetics of fertility restoration may be complete only then and it is, therefore necessary to identify a genotype that could restore fertility on these two steriles.
