The HaOr5 resistance gene is located in a large genomic insertion containing putative resistance genes and provides resistance to O. cumana, preventing successful connection to the sunflower root vascular system. Orobanche cumana (sunflower broomrape) is a parasitic plant that is part of the Orobanchaceae family and specifically infests sunflower crops.

- Crop wild relatives are important for improving crops by providing genetic traits that help with climate change and disease resilience.
- Research on sunflowers revealed that while introgressing wild genes can introduce beneficial genetic diversity, it often negatively affects yield and quality due to linkage drag.
- The study suggests that breeding should prioritize closely related wild relatives to minimize adverse effects while enhancing desirable traits in cultivated sunflowers.
Wall., sunflower broomrape, is one of the major pests for the sunflower crop. Breeding for resistant varieties in sunflower has been the most efficient method to control this parasitic weed.
