In order to achieve economic efficiency, research organizations have established rigorous, quantitative methods for priority setting. One such organization, the Rockefeller Foundation, has drawn on this report to help determine the research goals it should emphasize in its funding. A review of the problem of priority setting is presented followed by a discussion of approaches that have been used previously. Several chapters demonstrate how a number of areas of plant science research have contributed to gains in rice productivity and also assess the current challenges of genetic improvement and pest control. The economic framework for priority setting and previous methods are reviewed, followed by a series of country case studies which provide more practical applications.

Se ha avanzado considerablemente en el desarrollo de nuevas variedades de arroz de la India oriental, aunque la literatura sobre este tema es limitada. La evidencia de esto es el desarrollo y la liberación de muchas nuevas variedades mejoradas. Al menos 20 de estas variedades han sido liberados en la India de tierras bajas de secano traslado Network Cría Oriental (EIRLSBN). Además de producir nuevas variedades, esta red ha llevado a cabo una importante investigación sobre muchas características de alta prioridad y ha identificado los nuevos padres donantes, grupos de madurez clave para la región, las líneas de élite que se pueden trasplantar en tiempos normales o retardada, y perfiles de variedades de destino para este de la India. Más importante aún, la red ha sido un modelo ejemplar para las alianzas sinérgicas de mejoramiento del arroz. Demuestra los beneficios de la colaboración científica regional e internacional para trabajar para superar la inseguridad alimentaria. En efecto, ha influido en la formación y la estructura de muchas otras redes de cría.
