Rapeseed, the third most important oilseed globally, is a valuable alternative winter crop to wheat and barley, providing raw materials for edible oil and biofuels. Since 2007, INTA Paraná has focused on genetically improving rapeseed in Argentina, resulting in four competitive varieties that enhance soil health and subsequent crop yields. These varieties are also seen as sustainable sources for biodiesel and Sustainable Aviation Biofuels (SAF). INTA continues to refine management practices and genetic traits, with performance tests across various regions and promising germplasm evaluations in Uruguay and Paraguay. The cultivars are registered and commercialized.
