Marcadores moleculares como herramienta para la caracterización y mejoramiento genético de plantas
Efficient utilization of genetic resources of plants depends on their adequate characterization. Traditionally, this characterization has been made using phenotypic traits, which have helped to differentiate various genotypes, but not always in an accurate way because they are affected by environmental effects. DNA markers that are no subjected to these influences, provide an opportunity to examine and describe more precisely the genotypes and their relationships at a genetic level. During last two years, molecular markers have been used in CATIE for studies on different species such as, Pachyrhizus tuberosus (yam bean), Theobroma cacao (cocoa), and Swietenia macrophyla (mahogany). Studies on Quasia amara (quasia) have also started this year. The obtained information is useful to improve organization and utilization of germplasm collections, to design future collection strategies, and to organize better the improvement programs of these species.
