Article Abstract:
The interaction between two different genomes after hybridization is studied using genetic mapping techniques. It is revealed that although similarity exists in some portions of the two genomes for potential recombination, structural differences exist in the form of substantial segregation distortion, translocations and rearrangements that are likely to affect hybrid sterility and performance after hybridization.

Article Abstract:
The actual genetic relationships among the native canes and the extent to which they contributed to the commercial hybrid germplasm are the subject of speculation over the years. Genetic analysis of 43 presumed native Hawaiian S. officinarum clones using 228 DNA markers confirmed them to be a group distinct from the modern hybrid cultivars.

Article Abstract:
Complex polyploids display diverse chromosome pairing affinities and offer favorable situations for studying meiosis. The study reveals a continuous range of pairing affinities between chromosomes and indicates a strong role of individual chromosome features.
