Abstract

In this study, bunch oil content and fatty acid profile in the Elaeis oleifera species from Taisha, Morona-Santiago, 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%.

大沙油桐（Elaeis oleifera TAISHA-ECUADOR）、桂油桐（Eraeis guinensis Jacq。，种间杂交与回交

本研究测定了厄瓜多尔莫罗那-圣地亚哥泰沙地区Elaeis oleifera种及其种间杂交后代和回交与几内亚Elaeis的束油含量和脂肪酸谱。结果表明，太沙油鸡平均束油含量为10.74%，低于杂交种(25.80%)、回交(25.98%)和豚鼠(29.49%)。中果皮中脂肪酸含量最高的是C16:0、C18:1n9和C18:2n6，但与其他基因型相比，其棕榈酸含量较低(27.82%)。由于与几内亚伊蚊的行为相同，C18:1n9没有统计学上的差异，因此不能归类为高含油物质。而属于不饱和脂肪酸组的C18:2n6，其值高于其他任何一种物质，说明其油合成比美洲不同地区的其他油籽油更容易将C18:1转化为C18:2。平均碘值为76.93%，杂交为67.14%，回交为60.20%，几内亚伊蚊为55.65%。
