Abstract

Nigerian PS1 and PS2 materials are a new and potentially useful source of breeding materials for the Malaysian Oil Palm Industry. Direct utilization is opined to be less promising except for some selected palms with exceptionally good characteristics such as dwarf ideotype population 12 in PS1 and high carotene and iodine value I.V. in PS2. As such most of the work done at UP Bhd in utilizing these materials in the short and medium term involves introgressing the Nigerian selections with UPBs advanced is still to try to obtain high yielding pure Nigerian advanced breeding lines through further cycles of breeding and selection of Nigerian germplasm. This will offer breeders an alternative population in addition to the current materials. Based on the results obtained todate at UP Bhd introgressions of PS1 Nigerian teneras with UPB teneras Pisifera population have succeeded in producing some high yielding and potentially good pisifera lines. PS2 Nigerian dura selections have also shown to combine well with UPBs Deli duras to produce high yiledings dura lines. In addition the introgressions have added new genetic variability into the Deli ecotype whereby new and potentially high yielding dura mother palms with IV57.5 have been identified for high I.V. DxP seed production. Progeny testing of Nigerian PSII duras with I.V. pisiferas have produced some tenera progenies from which high yielding DxP ortets with I.V. values ranging between 58.0 and 61.0 have been identified for cloning. Nigerian tenera 128/0.151 from PS II has been used as a source of high I.V. E. guineensis parent in the interspecific F1 hybrid and backcrossing programmes. Several high yielding backcrosses have also been identified I.V. 65 as ortets for cloning. Further work is in progress to improve these materials via the next cycle of breeding and selection.
