Recent studies, including one by Embrapa from 2019 to 2023, have highlighted the challenges and advancements in wheat and triticale cultivation in central Brazil, particularly in the face of water scarcity and climate change. The research identified the BRS 404 wheat cultivar as notably drought-resistant, outperforming others with up to seven more bags per hectare under drought conditions. This finding underscores the importance of selecting resilient cultivars for the increasingly arid conditions of the Cerrado region, where wheat cultivation is expanding despite environmental challenges like dry spells and heat waves. These studies emphasize the critical need for strategic cultivation practices and genetic improvement programs focused on drought tolerance to ensure sustainable wheat production in tropical climates.

An Embrapa study to evaluate wheat's tolerance to water deficit showed that the BRS 404 cultivar can represent up to seven more bags per hectare in years with little rain in central Brazil. The research evaluated the tropical wheat yield of the main rainfed cultivars available on the market in the period 2019-2023. To assess wheat's tolerance to water restriction, researchers from Embrapa Trigo (RS) gathered performance data on rainfed wheat cultivars in Central Brazil over the last five years. On average, the yields of the BRS 404 cultivar were 12.4% higher when compared to other cultivars in use in the region, which could represent up to seven more bags per hectare. The variation was between 5% and 23% higher, considering that blast was a limitation only in 2019, while in other years the water deficit was the limiting factor. In these five years, the trials varied depending on the location and with the inclusion of new cultivars that arrived on the market during the period. See ...
