Screening wild sunflower species and F1 interspecific hybrids for resistance to broomrape

Abstract

Broomrape has become one of the most important threats to the cultivated sunflower. New sources of resistance genes are needed to maintain sunflower production. The objective of this research was to evaluate accessions of wild sunflower species and their F 1 interspecific hybrids with cultivated sunflower for resistance to race E.
