“…Thanks to the knowledge of the oil palm gene space (Low et al, 2014), meiosis regulators, such as DMC1orthologs (Wijnker et al, 2012) can be identified and then controlled. The frequencies of spontaneous haploids in seed progeny are very low, 1,100 haploids among 60 million seedlings (Dunwell et al, 2010). Cultures of oil palm microspores have not yielded doubled-haploids so far (Corley and Tinker, 2003).…”

African oil palm has the highest productivity amongst cultivated oleaginous crops. Species can constitute a single crop capable to fulfill the growing global demand for vegetable oils, which is estimated to reach 240 million tons by 2050. Two types of vegetable oil are extracted from the palm fruit on commercial scale. The crude palm oil and kernel palm oil have different fatty acid profiles, which increases versatility of the crop in industrial applications. Plantations of the current varieties have economic life-span around 25–30 years and produce fruits around the year. Thus, predictable annual palm oil supply enables marketing plans and adjustments in line with the economic forecasts. Oil palm cultivation is one of the most profitable land uses in the humid tropics. Oil palm fruits are the richest plant source of pro-vitamin A and vitamin E. Hence, crop both alleviates poverty, and could provide a simple practical solution to eliminate global pro-vitamin A deficiency. Oil palm is a perennial, evergreen tree adapted to cultivation in biodiversity rich equatorial land areas. The growing demand for the palm oil threatens the future of the rain forests and has a large negative impact on biodiversity. Plant science faces three major challenges to make oil palm the key element of building the future sustainable world. The global average yield of 3.5 tons of oil per hectare (t) should be raised to the full yield potential estimated at 11–18t. The tree architecture must be changed to lower labor intensity and improve mechanization of the harvest. Oil composition should be tailored to the evolving needs of the food, oleochemical and fuel industries. The release of the oil palm reference genome sequence in 2013 was the key step toward this goal. The molecular bases of agronomically important traits can be and are beginning to be understood at the single base pair resolution, enabling gene-centered breeding and engineering of this remarkable crop.

“…Population molecular diversity studies for breeding heterotic population organization, germplasm prospection and core collection which facilitate the selection, maintenance and exploitation of key genotypes and populations have also now become standard practice in many oil palm breeding programs [31,32,33,34]. Related to these are also homozygosity testing which expedites development of inbred (also isogenic and recombinant inbred lines) via single seed descent or doubled haploidy [15,35].…”

Abstract. Biotechnological applications in oil palm breeding comprises tissue culture propagation (TC), genetic modification (GM), marker-assisted breeding (MAB), and marker-assisted selection (MAS). Commercial success of oil palm TC has been hampered by the fruit mantling somaclonal variation risk, inefficient cloning process and inefficient ortet selection. With the imminent availability of the mantling marker and subsequently markers for cloning and palm selection efficiencies, the scenario would change. Despite early enthusiasm, GM oil palm remains at the R&D level and only for the high oleic trait, because of technical complexity and public sensitivity. Marker-assisted breeding, population genetic diversity, homozygosity determination and linkage disequilibrium have made most impact in oil palm breeding. With the revelation of the oil palm whole genome sequence, the feasibility of MAS for many major quantitative gene locus (QTL) traits e.g. shell, fruit colour, mantling, long stalk, lipase are being expedited. Meanwhile for minor QTL controlling yield and other traits, oil palm breeders are testing the feasibilities of genomewide breeding/genetic value estimation for MAS of hybrid parents, families and individuals. Undoubtedly, biotechnological tools will continue improving but their success depends on the field breeder who provides the essential genetic trials to develop the biotechnological tools and to validate their utility.

The oil palm (Elaeis guineensis Jacq.) PENDAHULUANTanaman kelapa sawit (Elaeis guineensis Jacq.) merupakan tanaman C3 penghasil minyak nabati yang paling efisien (Lamade et al., 2009; Jaafar dan Ibrahim, 2012) dan mampu tumbuh pada berbagai agroekosistem (Firmansyah, 2014). Kelapa sawit mampu menghasilkan minyak rata-rata 4 ton/ha (Ngalle et al., 2014), 6-10 kali lipat lebih banyak dibandingkan dengan minyak yang dihasilkan oleh kedelai, biji matahari, biji rapa, dan tanaman penghasil minyak nabati lainnya. Kelebihan tersebut dapat memangkas biaya lahan, infrastruktur, pemeliharaan, dan panen. Buah kelapa sawit dapat dimanfaatkan sebagai bahan pembuatan sabun, margarin, minyak makan, gliserol, kosmetika, lilin, resin, oleokimia, biomassa, dan biofuel. Dari sisi upaya pelestarian lingkungan hidup, tanaman kelapa sawit yang merupakan tanaman tahunan berbentuk pohon (tree crops) dapat berperan dalam penyerapan gas rumah kaca, mampu menghasilkan oksigen, dan jasa lingkungan lainnya seperti konservasi biodiversitas atau ekowisata (Goenadi et al., 2005). Indonesia menjadi negara produsen CPO terbesar di dunia mengungguli Malaysia pada tahun 2007. Produksi minyak kelapa sawit mencapai lebih dari 30 juta ton pada tahun 2015. Ekspor minyak kelapa sawit Indonesia ditujukan ke China, India, Belanda, Pakistan, dan Jerman.Bibit kelapa sawit umumnya berasal dari benih hibrida (hasil persilangan) antara Dura dan Pisifera (DxP). Penggunaan varietas unggul kelapa sawit hibrida merupakan komponen terpenting dalam lonjakan
