dcterms.abstractThe Rapid Generation Advancement (RGA) Platform has been established with the primary purpose of accelerating the fixation process of improved lines for subsequent selection in breeding programs. This approach aims to develop fixed improved lines in less time, generating new parental combinations with the necessary traits to ensure crop stability and profitability. Reducing the time required for breeding processes and improving the precision in selecting improved lines are key parameters that ensure an increase in the rate of genetic gain. This study aims to describe the progress of the Hybrid Rice for Latin America (HIAAL) consortium in obtaining lines in less time by using the RGA platform. HIAAL seeks to facilitate producers' access to hybrid rice technology through research and partnerships with the public and private sectors in Latin America. Within this context, it conducts work to improve the parental lines of these hybrids. To achieve this, 24 crosses were carried out, generating combinations among the 10 most heterotic parents of the consortium. These crosses were advanced from the F1 to the F5 generation within the facilities of the RGA platform. Subsequently, each line was multiplied in the field to evaluate its resistance to white leaf virus and Pyricularia. The selection process resulted in 405 lines being chosen for evaluation in hybrid cross trials. The RGA platform significantly contributes to the consortium, as it allows a large number of cross trials to be conducted in less time, thereby determining the genetic value of the parentals and ensuring the optimal recycling of parentals.en_US
