In genetic improvement of oil palm (Elaeis guineensis Jacq.), categorical variable represented a main part of information used to determine differentiation among populations of genitors selected from the reciprocal recurrent selection program (RRS). The disjunctive power of these variables has been tested on 134 genitors selected from populations of the first, second and third cycle of RRS. The categorical variables used to differentiate these populations are those that permitted to have some information on the geographical origins and the parental genealogies of those genitors. The factorial analysis of those categorical variables, permitted to assess the disjunctive power of each of the two main criteria of divergences of selected genitors' populations. The criteria "geographical origin" represented 14% of total disjunction expression of selected parents' populations. The criteria "parental genealogy" represented 70% of total disjunction expression of selected parents' populations. The use of these two criteria can constitute one fine alternative to the use of molecular data in diversity studies of selected oil palm populations.
