Necrosis inducing BCMV isolates were obtained from a range of wild and forage legume species growing in Uganda. Thirteen distinct isolates were identified on the bases of symptoms, pathogenicity in bean differential cultivars, serology, immunosorbent electron microscopy, seed-and aphid-transmissi...
