| description | More nutritive rice against malnutrition in Latin America Three topics are addressed briefly: (1) information available on the Fe and Zn contents of the grain of 11 rice cultivars; (2) factors affecting its contents; and (3) a plant breeding strategy proposed to increase the nutritional value of rice in Latin America. The data obtained are backed up by results obtained by the International Rice Research Institute (IRRI) and reveal significant differences among cultivars regarding rice grain Fe and Zn contents in both rough and polished rice. Acceptable Fe and Zn contents were also observed in several commercial varieties; these, however, were never selected to improve this aspect of nutritional quality. Recent scientific data indicate that plant breeding is an effective and reliable tool of reasonable cost to develop improved germplasm with a better nutritional value than current varieties. Research conducted by IRRI, within the framework of the HarvestPlus project, and by CIAT, through the AgroSalud project, indicates that genetic variability does exist in rice regarding grain Fe and Zn contents. In conclusion, it is considered feasible to improve the nutritional quality of rice in Latin America, and advances have been made in several areas. |

Se tratan brevemente tres temas: 1) la información disponible sobre el contenido de hierro (Fe) y zinc (Zn) del grano en 11 cultivares de arroz; 2) los factores que afectan ese contenido; y 3) una estrategia de fitomejoramiento que se propone para incrementar el valor nutricional del arroz en América Latina. Los datos obtenidos, que son sustentados por los resultados del Instituto Internacional de Investigaciones sobre el Arroz (IRRI), indican diferencias significativas entre los cultivares respecto al contenido de Fe y de Zn del grano, tanto en el arroz integral como en el arroz pulido. Se observó además un contenido aceptable de Fe y de Zn en algunas variedades comerciales; éstas, sin embargo, nunca fueron seleccionadas para mejorar este aspecto de su calidad nutricional. Datos científicos recientes indican que el fitomejoramiento es una herramienta eficaz, confiable y de costo razonable para desarrollar germoplasma mejorado, cuyo valor nutricional sea mayor que el de las variedades corrientes. Las investigaciones realizadas por el IRRI, en el marco del proyecto HarvestPlus, y por el CIAT, a través del proyecto AgroSalud, indican que hay variabilidad genética en el arroz respecto al contenido de Fe y de Zn de su grano. En conclusión, se considera que es factible mejorar la calidad nutricional del arroz en América Latina, tarea en la que se ha logrado avanzar en diversas direcciones. 2010 2017-06-20T09:02:30Z 2017-06-20T09:02:30Z Book Chapter https://hdl.handle.net/10568/82506 es Open Access application/pdf International Center for Tropical Agriculture Martínez Racines, César Pompilio; Borrero, Jaime; Duque E., Myriam Cristina; Carabalí, Silvio James; Silva, James; Tohme, Joseph M. 2010.
