Abstract
During 1990/91 and 1996/97, 6800 groundnut germplasm accessions originating from South America, Africa, and Asia were evaluated for resistance to rosette disease (caused by groundnut rosette umbravirus, its satellite RNA and groundnut rosette assistor luteovirus) using an infector row technique in Malawi. Of these, 116, including 15 short-duration Spanish types, showed high levels of resistance to the disease. A high percentage of these resistant accessions were from West Africa, although resistance was also identified in accessions from Asia and southern Africa. Only 1 of the 1400 South American accessions was resistant. All disease-resistant accessions were susceptible to groundnut rosette assistor virus. It is suggested that these sources of resistance could prove useful in breeding programmes. The origins of rosette resistance in groundnuts are discussed.
