Reaction of Lycopersicon species and varieties to Potato virus Y (PVY(NTN)) and Tomato mosaic virus (ToMV).
Virus susceptibility of 33 Lycopersicon species and varieties to NTN strain of Potato virus Y (PVY(NTN)) and Tomato mosaic virus (ToMV) were studied. Inoculated plants were tested for infection symptomatologically, serologically and by back inoculation as well. New incompatible and compatible host-virus relations have been determined. All tested plants were susceptible to ToMV. However, Lycopersicon esculentum Mill. convar. parviboccatum Lehm. var. cerasiforme (Dun.) Alef. s.l., L. peruvianum (L.) Mill. and L. hirsutum Humb. et Bonpl. were extreme resistant (immune) to PVY(NTN). Other species were susceptible. Resistant lycopersicon genotypes could be used as sources for virus resistance.
