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 RTSO5 linked to the sunflower Or5 locus conferring resistance to broomrape that belong to race E. The identification of 650 bp amplicon at 27 genotypes reveals the presence of Or5 gene; the missing of this amplified product at the maternal genotype Xenia and at the male sterile genotype No.7 suggests the susceptibility to race E.
