Pathogenic diversity within field populations of Orobanche cumana and different reactions on sunflower genotypes

2006-12-01

Abstract excerpt

Different races of the parasitic Orobanche cumana (sunflower broomrape) have been reported in Spain, race F being the most virulent. Full resistance in sunflower to races A-E is achieved with each of the single major genes Or₁ to Or₅ respectively. However, parasitised hybrids allegedly resistant to race F were observed in early 2002. The purpose of this study was to verify broomrape incidences (BI) on resistant su...
