Abstract
In this study, bunch oil content and fatty acid profile in the Elaeis oleifera species from Taisha, MoronaSantiago, Ecuador, its interspecific hybrid descendants and backcrosses were determined in contrast to Elaeis guineensis. Results showed that E. oleifera from Taisha presented an average of 10.74% oil in bunch, being lower than those presented by hybrids of 25.80%, backcrosses of 25.98%, and E. guineensis of 29.49%. The most abundant fatty acids in the mesocarp corresponded to C16:0, C18:1n9, and C18:2n6, where E. oleifera from Taisha, although it had a lower content of palmitic acid (27.82%) compared to the rest of the genotypes. This did not present statistical differences for C18:1n9 because of the same behaviour as an E. guineensis, and therefore did not classify as a high oleic material. However, for C18:2n6, which is in the group of unsaturated fatty acids, it presented higher values than any of the other materials, indicating that its oil synthesis converts C18:1 to C18:2 more easily than other E. oleifera of different places in America. The average iodine value was 76.93%, compared to hybrids with 67.14%, backcrosses with 60.20%, and E. guineensis with 55.65%.
