The cassava cultivars BRS 417, BRS 418 and BRS 419 are the first specifically developed for flour and starch production in the Cerrado biome of Central Brazil. They are promising for higher yields, lower production costs (mechanical planting) and the increase of genetic variability in cassava crops.
