The FELDA Agricultural Services Corporation has evaluated the performance of various D x P and D x T progenies of Yangambi, La Me, AVROS, NIFOR and fertile pisifera origins in Sungai Tekam, which is located in the interior of Pahang state in Peninsular Malaysia. The mean FFB yield for these groups of progenies, ranged from 163.7 to 177.2 kg/palm/year (equivalent to 22.10 to 23.92 t ha when calculated at 135 productive palms per hectare). The highest yielding progenies from the various groups gave between 185.3 to 202.0 kg/palm/year (equivalent to between 25.02 to 27.27 t ha). The D x P (fertile pisifera) group was characterised by thicker shells and bigger kernels. This has resulted in a low oil yield of 4.38 t ha. The best oil extraction rates from the DxP/DxT (NIFOR) and DxP/DxT (Yangambi) group were 24.4 and 23.6 respectively, with oil yields of 5/39 and 5/28 t ha respectively. The DxP (AVROS) gave 5.29 t ha of oil yield, whereas DxP/DxT (La Me) gave 5/17 t ha due to a lower oil extraction rate. The best individual progenies have oil yields ranging from 5.83 to 7.07 t ha with great differences in height increment between them. The DxP/DxT (La Me) and DxP/DxT (Yangambi) groups were considerably slower in height increment at 0.52 m/year and 0.53 m/year respectively when compared with the DxP (AVROS), DxP/DxT (NIFOR), and DxP (fertile pisifera) groups, which grew at 0/69, and 0.57 m/year respectively. Four unsaturated fatty acid composition, the DxP/DxT (La Me) group gave the highest iodine value of 54
