New races of Puccinia helianthi are continuously evolving and overcoming resistance genes, resulting in a continuous threat for the crop. The deployment of hybrids with simple resistances has exacerbated this problem. Combination of the appropriate R-genes could result in a resistance more difficult to overcome. The identification and characterization of new durable sources of sunflower rust resistance is a high priority for both researchers and industry. There is a possibility of breeding for high coumarin content to improve resistance at early stages of fungal development.
