Inside a panorama of a spectacular grain production in the last 10 years in Argentina, sunflower crop participates with an annual production of more than 3,500,000 t. During that period, many advances were made in the improvement of diseases resistance: Verticillium wilt, downy mildew and head rot. Also, oil yield per hectare continued to increase. The new hybrids have new qualities, for example imidazolinones resistance, which allows farmers to keep yields, although the soils destined to sunflower are minor quality of those destined to corn and soybean.
