An Attempt to combine the superior traits of Elaeis oleifera and Elaeis guineensis have been done through an interspecific hybrid cross and followed by pseudo-backcross 1 (pBC1). Observation of vegetative morphology and bunch components are presented in this paper. Two populations of pBC1 E. oleifera from the Suriname and Brazil origin were planted in 1990, 1993, 1995, and 2005, and were intensively observed for vegetative morphological properties and bunch components in November 2016 to February 2018. The results showed that almost all the individuals of pBC1 grew upright such as E. guineensis, no longer growing horizontally like the wild E. oleifera and the interspecific hybrid populations. The datas showed that the Suriname population plant architecture are compact or smaller than the Brazilian origin including the height increment and the size of the stem, the frond architecture and its components. Similarly, the bunch components show that the pBC1 Brazil is slightly superior to Suriname pBC1.

Construction of genetic linkage on oil palm derived SP540T was established in 2012-2015 in colaboration with PPKS, Indonesia with Neiker, Spain. DNA isolation was conducted in Molecular Biology Laboratory in PPKS Marihat meanwhile RAD analysis was performed in Laboratorio Biotecnologia Vegetal, Neiker, Spain. Genetic map construction was carried out using Restriction Site Associated DNA. A total 532 RAD fragments were applied to configure 16 Linkage Groups (LGs) which represented 16 chromosomes of oil palm. The map spans in 1269.9 map unit (mU) or 79.37 mU per chromosome in average and consists of RAD fragments which could be blasted to the DNA data base to identify candidate genes. Genenic map which had been formed is a fondation of constructing an IOPRI functional map (IOPRImap) when it is integrated with phenotypic data. The IOPRImap is expected to facilitate shortening oil palm selection cycle and defining a precise oil palm breeding strategy.

Information of oil palm flower and fruit development is very important in the observation plant morphology. This observation was carried out to complete information on vegetative and generative developments which are very useful for oil palm breeding. The success of plant breeding is measured from new varieties with specific advantages. This research used collections of Angola germplasm exploration which were planted in December 2012 at Adolina Estate of PT Perkebunan Nusantara IV. A total of 35 accessions were planted with RCBD designs in 2 trials. Vegetative observation per tree was carried out every year, since the plants were 2 years old. Observation of flower development is done by selecting 2 sample trees per accession by purposive sampling. A total of 70 trees were observed for flower development to become fruit every 10 days for each frond. Data on flower development were grouped by BBCH (Biologische Bundesantalt Bundessortenamt und Chemische Industrie) scale. In addition to the morphological and flower developmental stages, this study also calculated the age between developmental phases from the appearance of one leaf to the mature harvesting bunches in all midrib and tree samples. The results showed that generative development of the 35 Angolan accessions can be arranged according to the BBCH scale, beginning with the appearance of the first leaf, the appearance of the flower, female / male flowers blooming (receptic / anthesis), bunches formation to mature ripe bunches. AGO038 accession only requires 385 days (12.8 months), calculated from the time the first leaf appears to the mature ripe bunches, but AGO049 produces faster harvested ripe bunches when calculated from receptive female flowers of 144 days (4.8 months).

One of the secondary characters desired by oil palm planters is compact palm. Compact characters are characterized by slow height increment rate and short rachis length. Both characters are able to extend the economic life of oil palm and increase palm productivity. This paper will discuss the results of the evaluation of compact characters in several crosses of the third cycle progeny test of RRS (Reciprocal Recurrent Selection) program. The field trial was carried out on 21 crosses planted in 2008 at Dolok Sinumbah Estate. The observations showed that cross no. BJ62/05 and BJ05/05 have the potential to produce compact palm with the slowest height increment rates, the shortest rachis, and low LAI values. With these characters, these crosses can be planted at higher planting densities. Parents no. BJ5633D and 93-133-4T also have the potential to produce offspring with compact characters.

The oil palm breeding program for the species Elaeis guineensis and the backcross Elaeis oleifera is running slowly because oil palm is an annual plant. Therefore, it is necessary to have an alternative approach that can accelerate the oil palm breeding program. The SNP (single nucleotide polymorphism) genome-wide approach was then used to study the association between 18 phenotypes of bunch component in oil palm germplasm of E. oleifera from Suriname and Brazil Coari, some interspecific hybrids and some elite progeny of E. guineensis. The genotyping by sequencing (GBS) analysis produced a total of 459 million or approximately 798 thousand reads per sample and 3,252 SNPs were eligible for 456 genotypes. Using various association models, eleven normalized phenotypic data showed significant associations with 29 SNPs. Based on the annotations, 17 SNPs were related to genes wtih certain biological functions. Three SNPs were found to be at the exon of a gene, namely SNP4416, SNP349 and SNP3865, while the other 15 SNPs were at the intragenic to a gene. Four SNPs are common SNPs in phenotypes C16:0 and C18:1 as weel as in C20 0 and C20:1. This research shows the potential of SNPs that can be used as an alternative approach to E. oleifera backcross breeding, although further research is needed for validation purposes.
