Horizonte para a competitividade: anais. Porto Alegre: IRGAc2015  aThe upland rice (UR) cropped area in Brazil has decreased in the last decade. A portion of this can be attributed to the UR breeding program strategy adopted since the 1980s, according to which direct grain selection is targeted primarily to the most suitable areas. New strategies for an improved breeding under non-optimal conditions for UR require detailed characterization of spatial, inter-annual and sub-seasonal climate variability, particularly in relation to types, intensity and timing of drought events during the cropping cycle. This paper used a process-based crop model to support the Brazilian UR breeding program in efforts to adopt a new strategy that accounts for the varying range of environments where UR is currently cultivated.  aArroz  aModelo de simulação  aOryza sativa  aMelhoramento genético
