SUMMARY The effects of the Sudanese isolate of peanut stunt virus on the growth, nodulation and yield of two cultivars of broad bean (Viciafaba) were assessed in field trials in the Sudan for two consecutive years. Virus infection reduced both the fresh and dry weights of shoots and roots, reduced nodulation by up to 78% and significantly reduced the number and weight of seed per plant. Seed yield per area was reduced by up to 91% and 93% in the cultivars Silaim and Tarbia respectively. These adverse effects were attributed to the virulence of the virus strain, the time of infection and the susceptibility of the cultivars tested.
