Susceptibility of Capsicum breeding lines to NTN strain of Potato virus Y (PVY(NTN)) and Obuda pepper virus (ObPV).
The objective of this study was to examine the reaction of 12 Capsicum breeding lines to NTN strain of Potato virus Y (PVY(NTN)) and 16 lines to Obuda pepper virus (ObPV). Inoculated plants were symptomatologically and serologically checked for virus infection. Back inoculation was also carried out to Nicotiana tabacum 'Xanthi-nc' and N. tabacum 'Samsun' as indicator plants. Out of the 12 lines tested four (32.Bogyiszlói, 4/99 F2, 17/99 F2 and VI-61 in.) proved to be resistant (immune) to PVY(NTN). Seven Capsicum lines (9/99 F2, 17/99 F2, V-21 = 28/98 F3, V-28 = 36/98 F3, V-3 = 7/98 F2, V-6 = 13/98 F2, and V-10 = 17/98 F2) showed hypersensitive reaction to ObPV. Other breeding lines were susceptible to ObPV infection. One line (17/99 F2) showed immunity to PVY(NTN) and hypersensitivity to ObPV at the same time, therefore this one is considerably valuable for breeding pepper varieties for multivirus resistance.
