Mapping an avirulence gene in the sunflower parasitic weed Orobanche cumana and characterization of host selection based on virulence alleles
Sunflower broomrape (Orobanche cumana Wallr.) is a holoparasitic plant that jeopardizes sunflower production in most areas of Europe and Asia. Recently, populations with increased virulence, classified as race GGV, have been identified in Southern Spain's Guadalquivir Valley gene pool. These po...

| Summary: | Sunflower broomrape (Orobanche cumana Wallr.) is a holoparasitic plant that jeopardizes sunflower production in most areas of Europe and Asia. Recently, populations with increased virulence, classified as race GGV, have been identified in Southern Spain's Guadalquivir Valley gene pool. These populations overcome resistance genes in hybrids resistant to the predominant race FGV. This study aimed to (i) determine the inheritance and map the avirulence trait segregating in a cross between O. cumana individuals from populations EK23 (FGV) and IN201 (GGV), and (ii) characterize the host effect on the IN201 parental population allelic diversity. |
