Solanum brevidens showed calico mosaic symptoms in all the leaves, butS. etuberosum yellowing and yellow mosaic only in the top leaves, following graft-inoculation with alfalfa mosaic virus (AMV). The South American potato virus SB-22 infected latentlyS. brevidens following graft-inoculation, whereasS. etuberosum was not infected. AMV was not transmitted to the ovules of AMV-infectedS. brevidens andS. etuberosum. However, AMV was transmitted to the seeds ofS. etuberosum through pollen, resulting in 0.9% infected seeds.S. brevidens infected by SB-22 produced up to 20.2% of virus-infected germinable seed, and in some of the seed lots of infectedS. brevidens the germination rate was as low as 1.0%.
