Abstract

 

To broaden the genetic variability and especially to enrich agronomic qualities of oil palm (Elaeis guineensis Jacq.) populations of Group B used in the breeding scheme, a study was led on Lobé population, beforehand improved by PAMOL plantations of Cameroon. This evaluation was carried out in crosses with Deli testors derived from the second cycle of reciprocal recurrent selection scheme. The LM 2 T × DA 10 D and LM 2 T × DA 115 D crosses derived from the first breeding cycle were used as controls for the characterization of Lobé × Deli crosses. The bunch production components, vascular wilt susceptibility and vertical growth rate were used as criteria of evaluation. The Lobé × Deli crosses were characterized by bunch production lower than those of controls. These crosses had a higher vertical growth rate than those of controls. The Lobé × Deli crosses were susceptible to the vascular wilt. A study of general combining abilities made it possible to select one parent which cumulates maximum interesting characters. This parent had good general combining abilities for the precocity of bunch production, bunch production at the adult period and the vascular wilt tolerance. Prospects for utilization of this parent for the improvement of bunch production at young age and the diversification of sources of vascular wilt tolerance of populations used in the reciprocal recurrent selection scheme were discussed.

 

Key words: agronomic traits, Elaeis guineensis, reciprocal recurrent selection scheme.
