“…Sedangkan ekploitasi pada populasi E. oleifera dari Suriname dapat dilakukan pada semua pohon sebagai material tetua hibridisasi interpresifik. Salah satu manfaat populasi hibiridisasi interspesifik E. oleifera x E. guineensis yang pernah dilaporkan adalah eksploitasi karakter ketahanan terhadap penyakit Phytopthora palmivora (Navia et al, 2014) dan relatif tahan terhadap Ganoderma atau Fusarium (Cochard et al, 2005). Dengan demikian, hibridisasi interspesifik dapat meningkatkan keragaman genetik dengan adanya individu yang memiliki perpaduan alel dan karakter dari kedua tetuanya.…”

The oil palm species of Elaeis oleifera have some superior characters not possessed by E. guineensis species. The cross between E. oleifera x E. guineensis (E. o x E. g.) Is carried out to insert the superior character of E. oleifera into the E. guineensis species and to obtain individuals who possess a superior characteristic blend of both species. This study aims to determine the genetic diversity within and between populations of E. oleifera, as well as relationships between E. oleifera, E. guineensis and its interspecific hybrids. A total of 8 germplasm populations used were E. oleifera originating from Suriname and Brazil, E. guineensis population of Dura Deli and SP540T, and interspecific crosses of hybrid E. guineensis x E. oleifera from Colombia, hybrid E. guineensis x E. oleifera which is presumably from Colombia, as well as hybrid E. guineensis x E. oleifera from Brazil. A total of sixteen Simple Sequence Repeat (SSR) markers were used to analyze 92 individuals from 8 populations. PCoA results show that 8 Elaeis populations cluster in each group. The hybrid population of E. guineensis x E. oleifera suspected of Colombia has a very close kinship relationship with hybrid E. guineensis x E. oleifera from Colombia and clumped in the same quadrant. This suggests that the hybrid is indeed a hybrid of E. guineensis x E. oleifera from Colombia. The population of E. oleifera from Suriname showed the lowest genetic diversity, with the number of different alleles, specific alleles, heterozygosity values, and the percentages of polymorphic loci sequentially were 1.37, 0.18, 0.09, and 37.50%. While the population of interspecific interspecific crossbreeds of the E. oleifera species showed the highest genetic diversity with values of 3.81, 0.43, 0.62 and 100%.

“…The specifications relate to the mesocarp oil from Elaeis guineensis, which is the main commercial species planted in Asia, Africa, and South America [5]. A second interfertile species, Elaeis oleifera, which originates from South America, has higher unsaturated mesocarp oil contributed by elevated levels of oleic acid (C18:1) (~59%) and linoleic acid (C18:2) (~19%) with much reduced content of the saturated palmitic acid (C16:0) (~17%) when compared to E. guineensis [6].…”

“…However, resistance to disease, especially bud rot, has generated interest in E. oleifera, especially in South America, where the disease is widespread. Interspecific hybrids, which have intermediate yield and oil unsaturation levels of both species but inherit the resistance from E. oleifera, are the only materials suitable for planting in areas devastated by the disease in South America [5].…”

Sustainable Palm Oil—The Role of Screening and Advanced Analytical Techniques for Geographical Traceability and Authenticity Verification

Palm oil production from oil palm (Elaeis guineensis Jacq.) is vital for the economy of Malaysia. As of late, sustainable production of palm oil has been a key focus due to demand by consumer groups, and important progress has been made in establishing standards that promote good agricultural practices that minimize impact on the environment. In line with the industrial goal to build a traceable supply chain, several measures have been implemented to ensure that traceability can be monitored. Although the palm oil supply chain can be highly complex, and achieving full traceability is not an easy task, the industry has to be proactive in developing improved systems that support the existing methods, which rely on recorded information in the supply chain. The Malaysian Palm Oil Board (MPOB) as the custodian of the palm oil industry in Malaysia has taken the initiative to assess and develop technologies that can ensure authenticity and traceability of palm oil in the major supply chains from the point of harvesting all the way to key downstream applications. This review describes the underlying framework related to palm oil geographical traceability using various state-of-the-art analytical techniques, which are also being explored to address adulteration in the global palm oil supply chain.

“…Some studies have shown that modern cultivars are not well-adapted to recent climate changes (Martre et al, 2017). That finding is why oil palm breeding programs should be a multidisciplinary team effort that involves molecular tools (Rival, 2017), understanding the response of oil palm cultivars to limiting conditions due to abiotic (Rivera et al, 2012;Suresh et al, 2012;Jazayeri, 2015) and biotic factors (Moreno-Chacn and Camperos-Reyes, 2013;Avila et al, 2014;Navia et al, 2014) and conducting socioeconomic and crop feasibility studies either by defined agro-climatic regions (Pirker et al, 2016) or sitespecific cases where oil palm plantations can be established (Rhebergen et al, 2016), estimating limitations in available land (Meijide et al, 2017). In Colombia, there is a wide variety of oil palm genetic materials from different origins that can be used to start the search for sources of tolerance to different stresses.…”

Oil palm is the most productive and efficient oilseed crop in the world. Oil palm is planted in various geographical areas, where the frequency of extreme weather events is expected to increase because of climate change. The characterization of the response of oil palm cultivars to climatic conditions will allow identifying sources of tolerance to different types of stress caused by climate change, leading to the determination of the best genotype x environment relationships. The physiological responses, oil quality and yield of 11, six-year-old commercial oil palm cultivars with different origins were evaluated in two periods of contrasting climate conditions (rainy and dry seasons between the years 2008 and 2010). We found that the first impact of a period with water deficit was the reduction on gas exchange of all cultivars. Photosynthesis fell between 25% to 40% and transpiration decreased between 10% and 50%. During the dry season, leaf sugar concentration increased respect to the rainy season between 14% to 114%, and certain cultivars showed up to 27% higher photosynthetic water use efficiency. This variation could be due to the genetics of different cultivars. No significant differences were observed between the seasons in terms of oil quality. In general, changes in oil palm physiology observed in response to water deficit were related to the ability of the palm to adapt and survive periods of drought stress. The cultivars evaluated showed a good response to dry periods, with the IRHO being the most outstanding at each evaluated season .
