Estimation Of Variance

This research was conducted to study the performance of biparental dura × pisifera (D × P) progenies and their parental genetic origins on fruit set and yield components. Twenty-four D × P progenies developed from 10 genetic origins were used for this study. Analysis of variance showed that there was genetic variability based on the evaluation of individual progenies. Deli Ulu Remis × Nigeria of progeny ECPHP500 recorded the highest bunch number (22.91), and fresh fruit bunch (184.62 kg palm−1 year−1) and Deli Banting dura × AVROS pisifera (ECPHP550) had the highest average bunch weight (10.36 kg bunch−1 year−1). Progenies PK4674 (61.12%) and PK4465 (60.93%) had the highest fruit set, and the highest oil yield of 52.66 kg bunch−1 was noticed by progeny PK4674. Estimation of variance components, coefficients of variation, heritability, and genetic gain were calculated to establish the genetic variability. To validate the genetic disparity among the progenies, an unweighted pair-group procedure with arithmetic mean (UPGMA) and principal component was employed based on their quantitative traits. Through the UPGMA and principal component, the 24 progenies were clustered into 7 clusters, whereas cluster V had the highest fruit set (60.62%) and cluster IV had the highest oil yield (43.71 kg palm−1 year−1). For oil palm tissue culture and breeding programs, progeny PK4674 will be more useful for developing planting materials of high oil yielding with stable performance. However, we recommend that future studies incorporate molecular studies with conventional breeding.

Genetic Value

The additive genetic value for oil yield of 135 parents from several African populations tested in the first cycle of Indonesian Oil Palm Research Institute (IOPRI) breeding programme were estimated by best linear unbiased prediction (BLUP) using an unbalanced data set. These values were used to evaluate the possibility of reduction in generation selection time in an oil palm breeding programme. The ranks of parental additive genetic values obtained with early yield period and whole cycle was found to be consistent. These make that highly potential parents could be selected and recombined at a more precocious time in order to reduce the period between cycle. Since oil yield trait is mainly controlled under additive gene effect, the recombination should be done carefully for retaining as highly as possible this character in a parent to be improved.

High Heritability

Knowledge of the magnitude of genetic variability, heritability and genetic advance in the selection of desirable characters could assist the plant breeders in ascertaining criteria to be used in the breeding programmes. Twenty three introgressed oil palm progenies were evaluated at the Specialized Centre for Oil Palm Research of Cameroon, from 2004 to 2014 to estimate performance, genetic variability, heritability and genetic advance of oil yield and some economic traits in terms to select new oil palm parent materials with the traits of interest. The results revealed high variability among oil palm population for all the characters. Moderate estimates of the phenotypic and genotypic coefficient of variations associated with high heritability and moderate genetic advance as percent of mean were obtained for characters of fresh fruit bunch, bunch number, oil yield, kernel to bunch, kernel to fruit, kernel yield and height increment. The results suggest the effectiveness of selection method for these traits and their improvement through their phenotypic performance. LM11087T x LM2749D and LM12960T x LM7409D were obtained as superior oil palm crossing parents with the potential production of 6.26 ton ha-1yr-1 of crude palm oil; they can be exploited in seed production and further breeding program.<br /><br />Keywords: genetic advance, heritability, introgressed progenies, oil yield, Phenotypic<br /><br />

Hydrous Ethanol

In the small-scale dry oil extraction from palm fruit used by palm oil mills, mixed crude palm oil (MCPO) is extracted using a single screw press. The oil palm meal (OPM) by-product can be used as alternative feed for ruminants. Three parameters in further solvent extraction of oil are the ethanol-to-dried oil palm meal (DOPM) ratio (4.9–30.1 g.g-1), the extraction time (0.2–18.8 min), and the speed of stirrer (48–552 rpm). These parameters were optimized to for maximum oil yield by response surface methodology (RSM) while employing hydrous ethanol as the solvent. In our laboratory-scale oil extraction, the maximal experimental yield was 10.27 wt.% under the recommend condition: 20.1 g.g-1 ethanol-to-DOPM ratio, 11 min extraction time, and 300 rpm speed of stirrer. Moreover, prototype-scale oil extraction was tested with recirculated miscella for effects of the number of cycles on oil extraction from fresh DOPM. The results showed approximately 17.4 wt.% oil yield from 5000 g DOPM at the conditions recommended based on laboratory-scale experiments. In this study, recirculated miscella was used to extract oil from fresh DOPM. The first four cycles of oil extraction were almost as efficient as with fresh ethanol. Moreover, the protein content in the defatted oil palm meal (DFOPM) improved with oil extraction, because residual oil in DOPM was removed. The DFOPM should have less rancidity and longer shelf-life than DOPM.
