| Summary: | Molecular markers linked to broomrape resistance genes would permit a better understanding of genetic determinism of broomrape resistance in sunflower and facilitate early selection by screening the presence of a few specific DNA markers. We have provided analysis of 29 sunflower lines with SCAR marker RTS05 linked to the sunflower Or5 locus conferring resistance to broomrape that belong to race E. Identification of 650 bp amplicon at 27 genotypes reveal the presence of Or5 gene, missing of this amplified product at Xenia ♀ and cytoplasmic male sterile genotype # 7 suggest the susceptibility to race E.
