Following a survey involving wild oil palm groves in Côte d'lvoire as a whole in 1968, 17 parents were chosen at Yocoboué (southern Côte d'lvoire). Agronomic performance of the 17 parents was assessed through Deli x Yocoboué hybrids in 3 trials grown at La Mé (Côte d'lvoire), Mondoni and La Dibamba (Cameroon). When compared to the Deli x La Mé progenies used as controls, the Deli x Yocoboué hybrids produced 91% for total bunch weight and 86% for oil yields. However, the genetic variability within the Deli x Yocoboué progenies allows to select individual progenies as productive as the Deli x La Mé controls, for breeding purposes. A study of major agronomic traits led to the choice of parent YO 11 T, which combines the largest number of favourable traits. On average, Deli x Yocoboué progenies have slower vertical growth and are susceptible to Fusarium wilt, except 2 parents (YO 3 T and YO 9 T), which seem to be resistant.
