Lucía Afanador Kafuri Biología RAPD marker genetic distance genetic diversity Hevea brasiliensis cultivar identification Rubber (Hevea brasiliensis) represents a potential species for reforestation and commercial exploitation programmesin tropical countries such as Colombia. The genetic variability of a rubber collection kept at the ParaguaicitoExperimental Station in Buenavista in the Quindio department of Colombia was studied to improve knowledgeregarding this species and make better use of the trees available. A total of 25 clones, six from South-America, 17from Asia and two from Central-America were selected and analysed using RAPDs. DNA samples isolated fromthe trees were screened with 102 primers, 23 of which revealed polymorphism. Although a high degree ofsimilarity was found, clustering analysis of the data led to differentiating the rubber trees in terms of theirgeographical origin. Furthermore, genetic relationships were found amongst the clones which could help inselecting parents for use in breeding programmes and designing strategies for conserving clones having desirableagronomic traits. 2006 artículo científico 0123-3475 https://www.redalyc.org/articulo.oa?id=77680204 en http://www.redalyc.org/revista.oa?id=776 Revista Colombiana de Biotecnología application/pdf Universidad Nacional de Colombia Revista Colombiana de Biotecnología (Colombia) Num.2 Vol.VIII |
