“…Lucci et al [30] observed a decrease of 'P' (from 40.3% to 32.2%) and stearic (S) acid (from 3.8% to 2.7%), and a corresponding increase of 'O' (from 49.7% to 57.0%) and linoleic (L) acid (from 4.1% to 5.6%) in cold pressed oils from hybrid palm drupes collected 18-24 WAA. Conversely, other researchers reported an increase of 'P' (from 28.1% to 31.3%) and a decrease of 'O' (from 56.4% to 51.8%), but in a different ripening period (24)(25)(26)(27) [17].…”

“…Recent papers describe several characteristics of O × G hybrids, such as phenological stages, bunch morphology and yield [24,[38][39][40][41][42][43], agronomic performance [44][45][46][47], fruit abscission process [48], and genome size [15,49,50]. Even the mycorrhization process [51] and hydroponic cultivation [52] have been assessed, but limited investigations have been carried out regarding the interspecific hybrid palm oil (HPO) composition and its use in food products.…”

The consumers’ opinion concerning conventional palm (Elaeis guineensis) oil is negatively affected by environmental and nutritional issues. However, oils extracted from drupes of interspecific hybrids Elaeis oleifera × E. guineensis are getting more and more interest, due to their chemical and nutritional properties. Unsaturated fatty acids (oleic and linoleic) are the most abundant constituents (60%–80% of total fatty acids) of hybrid palm oil (HPO) and are mainly acylated in position sn-2 of the glycerol backbone. Carotenes and tocotrienols are the most interesting components of the unsaponifiable matter, even if their amount in crude oils varies greatly. The Codex Committee on Fats and Oils recently provided HPO the “dignity” of codified fat substance for human consumption and defined the physical and chemical parameters for genuine crude oils. However, only few researches have been conducted to date on the functional and technological properties of HPO, thus limiting its utilization in food industry. Recent studies on the nutritional effects of HPO softened the initial enthusiasm about the “tropical equivalent of olive oil”, suggesting that the overconsumption of HPO in the most-consumed processed foods should be carefully monitored.

“…A second species of South American origin, E. oleifera , has lower yield but interesting characteristics, such as higher unsaturated oil content, resistance to some diseases, and reduced height 26 , 27 . As such, interspecific hybrid breeding has often carried out to introgress the desirable traits from E. oleifera into E. guineensis through F 1 (OxG) and repeated backcrossing (BC) 13 , 28 , 29 . However, transcriptome analysis has not been reported for the interspecific OxG hybrids and, so far, is only available for interspecific backcross-one (BC 1 ) palms 20 .…”

Evaluation of transcriptome data in combination with QTL information has been applied in many crops to study the expression of genes responsible for specific phenotypes. In oil palm, the mesocarp oil extracted from E. oleifera × E. guineensis interspecific hybrids is known to have lower palmitic acid (C16:0) content compared to pure African palms. The present study demonstrates the effectiveness of transcriptome data in revealing the expression profiles of genes in the fatty acid (FA) and triacylglycerol (TAG) biosynthesis processes in interspecific hybrids. The transcriptome assembly yielded 43,920 putative genes of which a large proportion were homologous to known genes in the public databases. Most of the genes encoding key enzymes involved in the FA and TAG synthesis pathways were identified. Of these, 27, including two candidate genes located within the QTL associated with C16:0 content, showed differential expression between developmental stages, populations and/or palms with contrasting C16:0 content. Further evaluation using quantitative real-time PCR revealed that differentially expressed patterns are generally consistent with those observed in the transcriptome data. Our results also suggest that different isoforms are likely to be responsible for some of the variation observed in FA composition of interspecific hybrids.

“…IEH O×G progenies, from female caiaué and male oil palm plants of the Manicoré and La Mé populations, respectively, have shown a high potential for bunch production, with a high genetic variability for this characteristic, from the third to the sixth year after planting (Gomes Junior et al, 2016). Those progenies were derived from the same caiaué and oil palm populations used to develop the BRS Manicoré cultivar (Cunha & Lopes, 2010), which is the only IEH O×G grown in Brazil to date.…”

The objective of this work was to estimate selection gains for bunch production in hybrids obtained from “caiaué” (Elaeis oleifera) parents from the Manicoré population and oil palm (Elaeis guineensis) parents from the La Mé population, from the third to the eighth year after planting. Thirty-nine full-sibling progenies were evaluated in experiments conducted in a randomized complete block design, with four replicates and 12 plants per plot. The genetic gain estimates were 27.6% for the ten best selected F1 individuals, 13.7% for the four best selected progenies from parents of both sexes, 6.4% for the selected progenies of the five best male parents, 6.0% for the selected progenies of the two best families from male parents, and 4.0% for the selected progenies of the best descendants from male parents. Genetic gains for bunch production can be achieved, in the short term, through selection restricted to male parents, and, in the medium term, through selection of both male and female parents and cloning of F1 individuals.
