Conteúdo: | Genetic diversity within population of organisms and species is commonly measured using molecular-marker data. It has been claimed that more reliable diversity measurements can be obtained using selected genetically mapped marckers to in the data sets employed. However, this has not been tested. In the present study, using rice (Oryza sativa L.) as a model species, we have shown that the use of unmapped AFLP marckers reveals a pattern of diversity that is very similar to that obtained using a range of other marckers types and which reflects the known crossability groups within this species. In contrast, we show that use of mapped-marcker data can, in some cases, result in highly misleading patterns of diversity; the results obtained are critically related to the choice of parents used in the cross from which the mapping population was produced.
