CSIRO Tropical Agriculture, 306 Carmody Road, St Lucia, 4067, Brisbane, Australia aut Geographical distribution of genetic variation in Stylosanthes scabra revealed by RAPD analysis [Elektronische Daten] [C.J. Liu] A large number of S. scabra accessions have been accumulated worldwide. The majority of them were collected from Brazil and most of the others came from either Colombia or Venezuela. One hundred of these accessions, selected to represent the geographical distribution of the S. scabra collection held at the Australian Tropical Forages Genetic Resource Centre, were analysed using RAPD as markers. Seven of these accessions were found not to be S. scabra. Of the S. scabra accessions, the average dissimilarity value among Brazilian accessions (0.053) was much lower than that among Colombian (0.074) or Venezuelan (0.088) accessions, with an overall dissimilarity value of 0.059 among all the S. scabra accessions. Based on their dissimilarity values, most of these accessions could be separated into five groups. Geographical distributions for most accessions in each of these groups were well defined. Limited long distance introductions/dispersions of S. scabra between these regions were detected and they were mainly confined to Brazilian genotypes. The clustering results based on RAPD were compared with those based on morphological-agronomical characters, and the groups produced by the two different methods did not always match. Possible reasons for this discrepancy are discussed.
