PORIM Technology No. 20 : Chromosome Painting on Elaeis (Oil Palm) Chromosomes
The MPOB Technology series contains technical articles on specific aspects of the compoaition, properties, processing, refining, and end-uses of palm oil. It also covers oil palm technology
Genomic in situ hybridization was used to monitor the behaviour of parental genomes in Elaeis oleifera x Elaeis guineensis (OxG) hybrids. There was a clear differentiation between the E. oleifera (2n=32/ and E. guineensis (2n=32) genome. It was observed that there are 16 E. oleifera and 16 E. guineensis chromosomes. The interphase nuclei of the OxG hybrids had groups of chromosomes from both parental genomes in discrete, non intermixed domains.
