Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 3
Abstract
Among the viruses infecting chili, potato virus Y (PVY), chili veinal mottle virus (CVMV), tobacco etch virus (TEV), pepper vein banding virus (PVBV), pepper veinal mottle virus (PVMV) belonging to potyvirus group and cucumber mosaic virus (CMV) belonging to cucumovirus are economically the most important virus transmitted mechanically, and by aphids in a non persistent manner. In the present investigation, totally 16 parents and their 55 F1 hybrids were screened for four major viruses infecting chili viz., PVY, CVMV, PVBV and CMV. Seedlings were inoculated by mechanical sap inoculation method. Young leaves were observed for symptoms after 2 weeks of inoculation. In parental lines- PMR-57, RHRC-50-1, PMR-76, PMR-37, MI-2, AR-27, AR-28, AR-52, Perennial, Punjab Lal, Punjab Guchedhar, Pant C-1 and Tiwari. Crosses PMR-57 x Perennial, PMR-57 x Tiwari, RHRC-50-1 x Perennial, RHRC-50-1 x Punjab Guchedhar, PMR-69 x Perennial, PMR-69 x Perennial, PMR-69 x Punjab Guchedhar, PMR-69 x Tiwari and AR-28 x Perennial were expressed resistance to at least three viruses tested, and sixteen crosses expressed resistance to at least two viruses. Cross PMR-57 x Punjab Guchedhar expressed resistance to all the four viruses studied.
