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%.
