Broomrape represents the most important parasite that infested sunflower and produce low seed yield up to 70-80% in fields with races G, H or more. In south-east of Romania is identified the most virulent races of parasite Orobanche cumana, G, H and more. In location Braila, in year 2022, we tested 20 sunflower experimental hybrids belonging to National Agricultural Research and Development Institute Fundulea and differential set with sunflower genotypes for identified races of broomrape present in this area. All sunflower experimental hybrids was susceptible at races of broomrape and from differential set only one additional sunflower genotype was resistant at parasite broomrape, and this is old Romanian variety Neagra de Cluj (gene Or ???), accession Pl 650368, provided by North Central Regional Plant Introduction Station (NCRPIS), part of United States National Plant Germplasm System (NPGS). Old Romanian variety Neagra de Cluj, can be included in international set of differential for races G, H and I of parasite Orobanche cumana. |
