Résumé : Since 1996, following CIAT's recommendations, the CIAT/CIRAD projects have phased out Oryza sativa conventional crossbreeding activities and concentrate on broadening the genetic base of rice. The development and enhancement by recurrent selection of upland rice populations are the new breeding strategies to achieve the objective. Using a recessive male-sterile gene (ms), the development of rice population was eased. In Colombia, upland basic composite populations were enhanced using recurrent selectionbreeding methods. At each enhancement cycle, fertile plants are selected and are the startingpoint of progeny selection. In 2002, a total of 619 lines was evaluated. Advanced lines are evaluated in yield trials with CORPOICA.
