Determination of the fatty acid and triglyceride compositions of the F,(Elaeis guineensis X E. oleifera), F2 and the backcross hybrid mesocarp oils demonstrated that most fatty acid and triglyceride compositions of oils from hybrid palms are intermediate between those of their respective parentals. These data, as well as the acyl group (saturated/palmitate and unsaturated/oleate) distribution of triglycerides of the F2 mesocarp oils provide genetic proof for codominance in the F2 generation which shows a characteristic segregation into the co‐dominance ratio of 1:2:1 (i.e., 1 E.guineensis: 2 F1 hybrid: 1E. oleifera). Similar analyses into the backcross hybrid mesocarp oils on the whole confirmed co‐dominance when the backcross ratio of 1:1 was obtained. These results are used to develop the Co‐Dominance Theory ofElaeis palm hybridization which makes successful predictions for mesocarp oils from the different hybrid palms.
